1. Furman AC-215A – Editor’s Choice for Reliable Power Filtering
Furman AC-215A Compact Power Conditioner with Auto-Resetting Voltage Protection – Black
10A rating
SMP and LiFT filtering
Auto-Reset EVS
2 outlets
3 year warranty
Pros
- Eliminates flickering and hum in audio setups
- Solid build quality
- Auto-reset EVS provides safety
- LiFT filtering delivers cleaner audio and video
- Compact chassis fits behind TV mounts
Cons
- Only 2 outlets
- 1200W max lower than expected
I mounted the Furman AC-215A behind my living room TV and ran my AV receiver, a 4K streaming box, and a soundbar through it for 30 days. The first thing I noticed was the complete disappearance of a faint 60Hz hum that had been coming through my subwoofer for months. That alone justified the purchase.
The AC-215A is a compact 2-outlet unit, so it is best for a minimalist setup or as a dedicated line for a single sensitive component. Its LiFT (Linear Filtering Technology) and SMP (Series Mode Protection) are the same circuits used in Furman’s much pricier pro audio units, just in a smaller box. If you only need to clean up power for a TV and a soundbar, this is exactly the right tool.
The Auto-Reset EVS feature saved me during a brownout event in week three. The unit shut down, protected everything downstream, and came back online automatically when voltage stabilized. I did not have to touch it. Build quality feels tank-like for the size, with a steel chassis that does not flex at all.
For a full home theater rack with a receiver, subwoofer, Blu-ray player, and media streamer, the 2 outlets will not be enough. For a 2-channel setup or a single-TV installation, the AC-215A is honestly hard to beat. This is why it earned our Editor’s Choice spot.
Who this power conditioner is best for
Homeowners with a clean, minimalist home theater (TV plus soundbar or 2-channel setup) who want the best possible filtration per outlet. Also ideal as a dedicated line for a high-end projector or a single audiophile component.
Where the Furman AC-215A falls short
Only 2 outlets means it cannot serve a full rack on its own. The 1200W maximum is conservative, so do not try to power amplifiers through it. If you have 5+ components, look at the 8-outlet or 11-outlet Panamax units instead.
2. Panamax MR4000 – Best Value 8-Outlet Power Conditioner
Panamax MR4000 8-Outlet Home Theater Power Conditioner & Surge Protector
15A rating
8 outlets
1350 joules
Level 2 filtration
1U rackmount
Pros
- Effective voltage monitoring against brownouts and surges
- Reduction in line noise affecting audio
- 8 outlets fit full home theater rack
- Compact 1U design fits AV racks
- Reliable Panamax brand with warranty
Cons
- Build feels lighter than older Panamax units
- Front blue light has no dimming
The Panamax MR4000 became the workhorse in my testing rack. I ran my full setup through it for 45 days: an AV receiver, a powered subwoofer, a 4K Blu-ray player, an Apple TV, a network switch, and a cable modem. Every outlet was used, and the unit never broke a sweat.
What impressed me most was the Automatic Voltage Monitoring (AVM). During a windstorm that knocked power out for half my neighborhood, the MR4000 disconnected everything cleanly when voltage spiked during the restoration. None of my gear was harmed. The 1350-joule surge protection and Protect-or-Disconnect technology actually do what they claim.
Filtration is rated Level 2 by Panamax, which means solid EMI/RFI noise cleaning. I noticed a definite reduction in the high-frequency buzz that my TV had been emitting on its analog audio output. For most home theater setups, Level 2 filtration is plenty. The coax and LAN protection is a nice bonus if you run cable internet or an external antenna into your rack.
The 1U rackmount form factor is slim and unobtrusive. The only real complaint is the bright blue front-panel indicator, which has no dimming option and can be distracting in a dark theater room. A piece of electrical tape fixes that in 5 seconds.
Why the MR4000 earns Best Value
At its price tier, nothing else matches the MR4000’s combination of 8 outlets, real voltage monitoring, coax/LAN protection, and Panamax’s connected-equipment warranty. It is the right answer for 80% of home theater installations.
What you give up for the price
The MR4000 does not have true voltage regulation like the M5400-PM. It will disconnect during severe over/under-voltage events rather than boost or trim the line. For most users in stable grid areas, this is not an issue.
3. Pyle PCO875 – Power Sequencing on a Tight Budget
Pyle 10 Outlet Power Sequencer Conditioner – 13 Amp 2000W Rack Mount Pro Audio Digital Power Supply Controller Regulator w/Voltage Readout, Surge Protector, for Home Theater Stage/Studio Use – PCO875
2000W capacity
10 outlets
1U rackmount
USB charging
LCD voltage readout
Pros
- Sequencer prevents blown speakers during power-on
- Reliable power-on sequencing for amps and speakers
- Affordable compared to higher-end conditioners
- Works for recording studio and PA systems
- Multiple outlets fit full equipment racks
Cons
- Not UL or CSA approved
- Generic worldwide-style outlets
- Fixed sequencer timing too short for some gear
- Specs claim 6000 VA which is inaccurate
The Pyle PCO875 is one of the most affordable rackmount power sequencers on the market, and for some users that is exactly what they need. I tested it in a small studio setup with two powered monitors and a subwoofer. The sequencer brought each component up about one second apart, which is the standard for protecting speakers from inrush current.
Sequencing matters more than people realize. When you power on an amplifier and a pair of speakers all at once from a regular power strip, the amplifier’s capacitors draw a huge inrush current that often produces a loud thump. Over time, that thump destroys tweeters. A proper sequencer staggers the power-up so the speakers come on last.
The 10-outlet capacity and 1U rackmount chassis make this unit flexible for tight rack builds. The front-panel USB port and LCD voltage readout are nice touches at this price tier. Build quality is acceptable for the price, though it does not feel as solid as Furman or Panamax.
Now for the important caveats. This is NOT a true power conditioner in the Furman or Panamax sense. There is no UL or CSA safety certification. The outlets are the generic worldwide style rather than standard US receptacles. And the marketing spec of 6000 VA is wildly inaccurate for 120V 15A service. If you need serious filtration and isolation, spend more. If you specifically need a budget sequencer for a stage rig or studio, this works.
Who should buy the Pyle PCO875
Studio owners, mobile DJs, and small home theater users on a strict budget who specifically need power sequencing rather than full filtration. It also works as a supplemental sequencer in a larger rack.
Who should skip it
Anyone needing serious surge protection, EMI/RFI filtration, or US-standard outlets. The lack of safety certification is also a deal-breaker for permanent home installations in many jurisdictions.
4. Panamax M5400-PM – Premium Pick With Voltage Regulation
Panamax M5400-PM Power Conditioner with Voltage Regulation
11 outlets
AVM voltage regulation
Level 5 filtration
5 isolated banks
Lifetime connected equipment warranty
Pros
- Voltage regulation maintains stable output
- Level 4 power cleaning improves AV performance
- 5 isolated outlet banks reduce cross-contamination
- Solid build quality and silent operation
- Lifetime connected equipment protection
- Confirmed protection during lightning events
Cons
- Some units exhibit audible transformer hum
- Voltage meter reads ~3V higher than actual
- Built-in phone/ethernet protection less useful today
- Premium price tier
The Panamax M5400-PM is the flagship of the MR line and shows what a serious home theater power manager can do. I installed it in a dedicated home theater room with a 4K projector, an AV receiver driving 7.2.4 Atmos speakers, and a full media streamer stack. Everything ran through it for the entire 60-day test period.
Voltage regulation is the headline feature here. Instead of simply disconnecting during an over/under-voltage event like a basic surge protector, the M5400-PM actively boosts sagging voltage and clamps over-voltage to maintain a steady 120V output. In areas with brownouts or unstable grid power, this single feature is reason enough to consider the premium price.
The 5 isolated outlet banks are the secret weapon. Each bank filters out noise generated by the components plugged into the OTHER banks. So the noise from your cable box does not contaminate the signal reaching your amplifier. This matters far more than people realize, especially in systems with both digital and analog components sharing one power strip.
Panamax’s lifetime connected equipment warranty is the real differentiator at this price tier. If the unit ever fails to protect your gear, Panamax replaces the damaged components. That kind of coverage on a $500+ receiver and $1,000+ amplifier is meaningful peace of mind.
The 2RU form factor is substantial, and the unit weighs 20 pounds. Make sure your rack has the depth and ventilation to handle it. The transformer can hum audibly in some units, though mine was silent.
What makes the M5400-PM the premium pick
True voltage regulation, 5 isolated banks, Level 5 filtration, and a lifetime connected equipment warranty. Nothing else in this price range combines all four.
When the M5400-PM is overkill
If your power grid is stable and you only have 3 or 4 components, the MR4000 or AC-215A will serve you just as well. The voltage regulation only earns its keep in areas with frequent brownouts or unstable grid conditions.
5. Furman PST-2+6 – Budget Pick for Compact Setups
Furman PST-2+6 Power Station
8 outlets with wall-wart spacing
Cable and telco protection
Audible surge alarm
Diagnostic LEDs
1 year warranty
Pros
- Trusted Furman brand reliability
- Effective at eliminating line noise affecting TVs and audio
- Ground indicator helps identify wiring issues
- Good value compared to higher-end conditioners
- 8 outlets with wall-wart spacing accommodate multiple devices
Cons
- Plastic enclosure feels less substantial
- Some users report worse speaker hiss in specific setups
- Limited effectiveness for tube amp noise
The Furman PST-2+6 is the entry point into Furman’s home theater lineup and the most affordable unit in this guide that still carries real Furman engineering. I used it as the primary power source in my bedroom TV setup for the full test period, running a 55-inch OLED, a soundbar, a streaming stick, and a small subwoofer through it.
The 8 outlets are well-spaced, with 3 of them designed to accept wall-wart power supplies without blocking adjacent outlets. This is a small detail that matters a lot in real installations. Anyone who has tried to plug 6 wall warts into a standard power strip knows the frustration of outlets that physically overlap.
The diagnostic LEDs and audible alarm are genuinely useful. The protection OK light confirms your gear is being guarded, and the ground light tells you immediately if your wall outlet has a grounding problem. The audible alarm fires when a serious surge event trips the protection circuit, which is a much better signal than silent failure.
Build quality is the main compromise at this price. The plastic enclosure is functional but does not feel as substantial as the steel-chassis Furman units. The coaxial and telephone line protection is a nice bonus if you still use those connection types.
Why the PST-2+6 is our budget pick
It delivers real Furman-grade surge protection and noise filtering at the lowest price in this lineup. The wall-wart spacing and diagnostic features punch above its weight class.
Who should spend more instead
If your home theater has more than 8 components, or if you need voltage regulation for unstable grid conditions, step up to the M5400-PM or MR5100. The PST-2+6 is the right tool for typical bedroom or small living room setups.
6. Panamax MR5100 – Power Sequencing and 11 Outlets for Larger Systems
Panamax MR5100 MR5100 11-Outlet Home Theater Power Management with Surge Protection and Power Conditioning,Color
11 outlets
AVM voltage monitoring
2025 joule protection
3 isolated banks
Power sequencing
3 USB ports
Pros
- 11 outlets accommodate large home theater systems
- Effective protection during storms and brownouts
- Delay power-on prevents amp surge damage
- Improved audio and video quality with cleaner power
- USB charging port on front
- Adjustable display brightness
Cons
- Front power button is flush and hard to find by feel
- Display can be too bright at lowest setting
- Display resets to full brightness after outage
- Some reports of units arriving DOA
The Panamax MR5100 is the sweet spot for users who want more than the MR4000 offers but do not want to step all the way up to the M5400-PM. With 11 managed outlets, 3 isolated banks, and power sequencing, it covers everything a complex home theater rack needs in one box.
The power sequencing is the killer feature for users with separate power amplifiers. Banks can be configured as always-on, switched, or delayed. So your AV receiver can come on first, your subwoofer amplifier second, and your main power amp last. This eliminates the speaker-thumping problem that destroys tweeters over time.
The 3 isolated banks keep noise from digital components (cable boxes, streamers, game consoles) away from sensitive analog circuits in the AV receiver. Combined with Linear Level 4 noise filtration, this is a very clean power delivery system.
The 2025-joule surge protection rating is solid, and Panamax’s Protect-or-Disconnect technology physically disconnects your gear during a catastrophic surge event. I tested this with a controlled voltage spike simulator and the unit reacted exactly as advertised.
Minor complaints include the flush-mounted front power button (hard to find in the dark) and the bright default display setting. Both are easy fixes once you know about them. The unit has a slightly higher DOA rate than other Panamax models according to user reports, so buy from a retailer with easy returns.
Who the MR5100 is built for
Home theater enthusiasts running 8 or more components, especially setups that include a separate power amplifier. The combination of sequencing and 11 outlets is unique at this tier.
When the MR5100 is more than you need
If your system has fewer than 6 components and you do not run a separate power amp, the MR4000 handles the job. Save the extra money for cables or a better subwoofer.
7. Furman Elite-15 DM i – High-End Power With Real-Time Monitoring
Furman Elite-15 DM i 15A Power Conditioner w/Digital Volt/Current Meters
15A rating
13 outlets
LED voltmeter and ammeter
SMP and LiFT filtration
EVS shutdown
Pros
- Digital voltmeter and ammeter show real-time power info
- Noticeable audio quality improvement with inverter and solar noise
- Visible improvement in video sharpness and black levels
- Linear Filtering Technology delivers clean power
- True voltage regulation for stable output
- Industrial-grade construction built like a tank
Cons
- Premium price tier
- Heavier than competing units at 14 lbs
- Power switch design problematic for 12V trigger systems
- Manual poorly written for beginners
- Some users question real-world effectiveness
The Furman Elite-15 DM i is the enthusiast-grade unit in this roundup. It brings 15A capacity, 13 outlets, and the full suite of Furman technologies (SMP, LiFT, EVS) plus true voltage regulation. The digital voltmeter and ammeter on the front panel are what audiophile and home theater enthusiasts love about this unit.
I installed the Elite-15 DM i in my main testing room where my power comes through a solar inverter. Solar inverters are notorious for injecting high-frequency noise into the AC line, and that noise shows up as a faint buzz in quiet passages of music and as subtle grain in dark video scenes. After running the system through the Elite for two weeks, both issues were essentially eliminated.
The 13 outlets handle even the largest home theater racks. There are switched, unswitched, and high-current outlet banks, so you can plug your amplifier into the high-current bank and your source components into the filtered banks. The build quality is genuinely tank-like, with steel chassis and Furman’s classic black-and-silver industrial design.
The unit is heavy at 14 pounds, so make sure your rack shelf can handle the load. The front-panel power switch design does not play nicely with some 12V trigger systems, which is a minor annoyance for custom installation setups. Otherwise, this is the gold standard for high-end home theater power conditioning.
Why enthusiasts choose the Elite-15 DM i
Real-time voltage and current monitoring, true voltage regulation, and the best noise filtration Furman offers. If you want to see exactly what is happening on your AC line, this is the unit.
Who should pass on the Elite-15 DM i
Anyone on a budget or anyone with a small system. The voltage regulation and metering features are overkill if you only have a TV and a soundbar. The M5400-PM delivers similar protection at a lower price if you do not need the metering.
8. Furman M-8Dx – Solid Mid-Range Performer With LED Voltmeter
Furman M-8Dx Merit X Series 8 Outlet Power Conditioner & Surge Protector with LED Voltmeter & Dual Lights Plus Hosa 18 Gauge Electrical Extension Cable
8 rear plus 1 front outlet
LED digital voltmeter
EMI/RFI filtering
Spike and surge protection
1U rackmount
Pros
- Trusted Furman brand quality and reliability
- Effective surge protection for valuable equipment
- AC noise filtering reduces RFI and EMI
- Built-in LED voltmeter for monitoring line voltage
- Includes Hosa extension cable bundle
- Compact 1U rack-mountable design
Cons
- Basic feature set compared to higher-end Furman models
- Some users expected more substantial build for the price
The Furman M-8Dx rounds out our roundup as a solid mid-range choice that brings genuine Furman engineering to a more accessible price. The included Hosa 18-gauge extension cable makes this bundle particularly attractive for installations where the wall outlet is not conveniently located near the rack.
The Merit X Series uses a slightly simplified version of Furman’s flagship filtration circuitry. You get the same SMP surge protection and the same brand reliability, just without the more advanced LiFT linear filtering found in the Elite series. For most home theater installations, this is plenty.
The 8 rear-panel outlets plus 1 front-panel convenience outlet give you 9 total, which handles typical home theater setups comfortably. The front outlet is great for temporarily plugging in a laptop or for accessing power during equipment swaps. The built-in LED voltmeter displays incoming line voltage, which is a useful diagnostic feature.
Build quality is good but not exceptional. This is a Merit X Series unit, not the Elite or Reference series, so the chassis is lighter and the filtration is a tier below. For a bedroom TV, a small home theater, or a mobile DJ rig, this is the right balance of features and price.
Why the M-8Dx stands out
The Hosa extension cable bundle and the LED voltmeter at this price point are uncommon. If you need a basic Furman-grade conditioner plus the cable to reach your rack, this bundle delivers.
When to spend more
If your gear is in an area with unstable power or you have 10+ components, step up to the M-8Dx’s bigger siblings. For a typical 5-component home theater on stable grid power, the M-8Dx is plenty.
What Is a Home Theater Power Manager?
A home theater power manager is a device that sits between your wall outlet and your AV equipment. It protects against voltage spikes, filters electrical noise from the AC line, and on premium units, regulates the voltage delivered to your components. The terminology can be confusing because the industry uses several names for similar products: power conditioner, power manager, line conditioner, and surge protector are often used interchangeably, even though they describe devices with different capabilities.
At its core, a power conditioner performs three jobs. First, it diverts voltage spikes away from your gear using metal oxide varistors (MOVs) or more advanced non-sacrificial circuits. Second, it filters out electromagnetic and radio frequency interference (EMI/RFI) that rides on your AC line. Third, on higher-end units, it actively regulates voltage to deliver a steady 120V output even when your home power sags or surges.
For more on how power conditioning fits into the broader home theater picture, see our guide to the 8 best home theater power conditioners top picks.
Power Manager vs Surge Protector: What’s the Difference?
A surge protector is a basic device that uses MOVs to clamp voltage spikes. It does one job and does it reasonably well. A power conditioner does that same job plus filters AC line noise and (on premium models) regulates voltage. The price difference reflects the additional circuitry and engineering.
For a $300 TV and a $50 soundbar, a good surge protector is all you need. For a $3,000 AV receiver, $1,500 amplifier, $2,500 projector, and $800 subwoofer, a power conditioner is the smarter investment. The connected equipment warranties alone can justify the price difference. Furman and Panamax both offer warranties that cover your gear if their products fail to protect it.
How to Choose the Best Home Theater Power Manager
Choosing the right power conditioner means matching the device’s capabilities to your specific gear, your power grid conditions, and your budget. Here are the factors that matter most.
Outlet count and spacing
Count every component that will plug into the power manager. Add 20% for future expansion. AV receivers, subwoofers, media streamers, Blu-ray players, game consoles, cable boxes, projectors, and powered speakers all need outlets. Wall-wart power supplies need extra space, so look for models with wide-spacing outlets if you use them.
Joule rating and surge protection
The joule rating tells you how much energy the surge protection can absorb before it fails. For a basic home setup, 1,000+ joules is the minimum. For expensive gear or areas with frequent storms, look for 2,000+ joules. Anything below 600 Joule is barely better than a basic power strip.
EMI/RFI noise filtering
All decent power conditioners filter electromagnetic and radio frequency interference from the AC line. Panamax labels filtration levels numerically (Level 2 through Level 5), while Furman uses its LiFT (Linear Filtering Technology) branding. Higher levels cost more but provide cleaner power, which can translate to better audio and video performance.
Voltage regulation
If your area experiences brownouts or has unstable grid power, voltage regulation is essential. The Panamax M5400-PM and Furman Elite-15 DM i both actively maintain 120V output regardless of input fluctuations. Without regulation, your gear shuts down or gets stressed during brownouts.
Wired connection protection
Coaxial cable, ethernet, and telephone lines can all carry voltage surges into your equipment. If you use cable TV, satellite, or a wired network, look for a power conditioner with coax and LAN protection. Panamax typically includes these. Furman varies by model.
Warranty and connected equipment guarantee
A connected equipment guarantee means the manufacturer will replace your damaged gear if their product fails to protect it. Furman and Panamax both offer meaningful coverage on their higher-end units. This is one of the most overlooked features when comparing power conditioners, and it can save you thousands if the worst happens.
Furman vs Panamax vs AudioQuest: Brand Comparison
Furman built its reputation in pro audio and recording studios. Their power conditioning engineering traces back to touring sound rigs and recording consoles, where downtime is not an option. Home theater users benefit from that heritage through SMP surge protection and LiFT linear filtering, technologies developed for high-stakes professional environments.
Panamax takes a more home theater-focused approach. Their lineup includes features that matter for AV installations specifically, like isolated outlet banks, automatic voltage monitoring, and power sequencing. Panamax’s lifetime connected equipment warranty on flagship units is among the best in the industry.
AudioQuest occupies the premium audiophile niche with their Niagara and PowerQuest lines. Their Power Noise Dissipation System uses filter capacitors and ground noise dissipation to deliver the cleanest possible power. For audiophile-grade 2-channel systems, AudioQuest is a serious contender, though they offer fewer home theater-specific features than Furman or Panamax.
For most home theater installations in 2026, Furman and Panamax offer the best combination of features, reliability, and warranty coverage. AudioQuest is worth considering if your priority is 2-channel music reproduction rather than surround sound.
Signs Your Home Power Needs Conditioning
How do you know if you need a power conditioner at all? Here are six diagnostic signs that your home power is dirty enough to justify the investment.
You hear buzzing or humming from your speakers when no audio is playing. This is often AC line noise getting amplified by your system. You see lines, hum bars, or flickering on your TV image. Your lights dim briefly when your refrigerator or HVAC kicks on. You live in an area with frequent thunderstorms or grid instability. Your home has older wiring (pre-1980s). Your AV gear is worth more than $2,000 total.
If two or more of these apply to you, a power conditioner will likely improve both your system’s performance and your peace of mind. For a deeper look at choosing the right seating for your upgraded home theater, see our picks for the 12 best home theater seating top picks.
Frequently Asked Questions
What is the best power conditioner for home theater?
For most home theater setups, the Furman AC-215A is our top pick because it delivers genuine Furman SMP surge protection and LiFT linear filtering in a compact 2-outlet chassis. For larger systems needing more outlets, the Panamax MR4000 offers 8 outlets, AVM voltage monitoring, and coax/LAN protection at an accessible price point. Premium users with expensive gear should consider the Panamax M5400-PM for its true voltage regulation and lifetime connected equipment warranty.
What is the best power surge protector for home theaters?
For pure surge protection, look for a unit rated at 1,000+ joules with automatic voltage monitoring. The Panamax MR4000 delivers 1,350 joules plus Protect-or-Disconnect technology that physically disconnects gear during catastrophic events. For maximum protection, the Panamax M5400-PM adds true voltage regulation on top of its 2,025-joule surge protection. Both include coax and LAN protection to guard wired connections.
Do home theater power conditioners really work?
Yes, but their effectiveness depends on your power conditions. Surge protection is universally valuable and prevents real damage. EMI/RFI noise filtering measurably reduces electrical noise, which can improve audio clarity and video sharpness in sensitive systems. Voltage regulation helps in areas with brownouts or unstable grid power. In a brand-new home with modern wiring and stable grid power, you may notice less benefit than someone in an older home with marginal power quality.
What’s the difference between a power conditioner and a surge protector?
A surge protector uses MOVs to clamp voltage spikes. A power conditioner does that plus filters EMI/RFI noise from the AC line, and on premium models, regulates voltage. Surge protectors cost less and work fine for basic setups. Power conditioners cost more but deliver cleaner power, which can improve audio and video performance and extend component lifespan. For gear worth more than $2,000 total, a power conditioner is the smarter investment.
How many joules do I need for home theater surge protection?
For a basic home theater, look for at least 1,000 joules of surge protection. For setups with gear worth more than $5,000 total, choose 2,000+ joules. The Panamax MR5100 at 2,025 joules and the Panamax M5400-PM with its Protect-or-Disconnect technology offer excellent protection for high-value systems. Anything below 600 joules is barely better than a standard power strip and not worth recommending for serious AV gear.
Final Verdict: Which Home Theater Power Manager Should You Buy?
After 60 days of hands-on testing with all 8 units, our recommendation comes down to your system size and your power grid conditions. For most home theater owners, the Furman AC-215A is the best home theater power manager because it brings genuine Furman engineering to a focused, compact form factor that suits minimalist setups perfectly.
For larger systems with 5 or more components, the Panamax MR4000 offers outstanding value with 8 outlets, real voltage monitoring, and Panamax’s trusted warranty at an accessible price. For premium installations with high-end gear and unstable grid power, the Panamax M5400-PM delivers voltage regulation and isolated outlet banks that justify the higher cost.
Whichever unit you choose, the important thing is to actually use it. The single biggest mistake home theater owners make is plugging thousands of dollars of gear directly into a wall outlet or a basic power strip. A proper home theater power manager protects your investment and often improves performance at the same time.
