      The only added feature to the M5400-PM that M5300-PM doesn’t have is voltage regulation. I would hardly call the regulator in this unit a voltage regulator. It is merely a transformer with four taps on it. When the sensor detects the voltage below 114 volts, it will switch over to one of the two higher voltages. Since it is a scalar voltage ratio, the output voltage will be between 115V – 124V. The same is true if your wall voltage goes 125V – 136V, it will switch to the tap which will lower by a ratio. This is the CHEAPEST voltage regulator in terms of design and cost. Given that, it is the most energy efficient which doesn’t mean a lot since it consumes 0.3 Amps with no load (that’s 36 Watts). I looked at the FFT of the power going into the M5400-PM and coming out the unit and there is no visible difference. The measured THD (Total Harmonic Distortion) using a RSA3408B (Spectrum Analyzer) did go from 2.1% to 1.4%, but that is the same filter in the M5300-PM. I also looked at the voltage on an oscilloscope and compared the signal before it enters the unit and on the output. Comparing the two reveals all the fluctuations on the line before and after remain the same. Meaning the unit will not condition your power to give your expensive equipment pretty clean sinusoidal voltages. The so called voltage regulator in the M5400-PM in my opinion isn’t worth the inflated price tag. Get your monies worth and go with the M5300-PM if you need that many outlets. And yes I have all the overpriced name brand home theater equipment that I desire to protect with what should be overly designed power management system.

      The best $700 I've ever spent!


      I recently purchased this Panamax power center to protect my home theater system. I have a Pioneer Elite plasma tv and a Pioneer Elite receiver with some B&W speakers, a PS3, XBOX360 and a DVR. As you can imagine, I've spent a lot of money on a home theater system and I wanted to make sure that it is fully protected. This power center was the one i had my eye on. I run every component through the power center. It has 5 isolated banks to eliminate noise and contamination to other outlets. One of the most important reasons I chose this power center is the AVM (automatic voltage monitoring). This feature is essential to me personally because where I live I do experience a lot of power outages and surges, so making sure that I have a surge protector that can detect unsafe voltages is critical. The final reason I chose this power center is for the filtration. The M5400 features one of Panamax's highest level of power cleaning and filtering, level 4+, which improves picture quality and sound, and I was pleasantly surprised when i saw the difference myself! I buy high end audio/video equipment and usually buy the protection plans. For instance, i purchased the protection plan for my TV, receiver, and speakers to make sure everything lasts, orh at least guarantee a brand new item in the event something can't be fixed. So I bought a high end power center for my equipment. But i do believe that buying a high end power center is one of the best things you can do to ensure long lasting equipment even if you didn't spend a massive amount of money on your components.

      Essential for a real cinema presentation!

      • My Best Buy® Elite MemberElite Member

      The m5400pm is essential for anybody trying to get the absolute best out of their home theater system. Power conditioning with HIGH current outlets transformed my theater from a better than good system into a true audiophile contender. My previous power conditioner was a stage 2 design by monster. It did a decent job but nothing like the panamax. The sound and the picture are greatly improved as advertised. I give a lot of credit to the High Current outlets. I have read that this feature when implemented correctly vastly improves the performance of power hungry amps. My system has two power hungry amps. My Marantz receiver (130W; two Channels driven) and 12" Polk Sub (150W continuous / 300W peak) definitely responded with more detail and presentation. Basically instead of hearing the speakers and the Sub I heard one well balanced blend of sound. More slam; less rumble. The whole sound stage revealed as if my seat got moved up from the far side to the "Sweet spot." More resolution in audio; better color and motion in the video. Plus I know my voltage is clean and stable. After the opening scene of Mad Max Fury Road I realized I had made probably the best investment I could have made for my home entertainment. I have heard some people say the operation is noisy but I can't hear a thing from my unit.

      Overall It Does What It Advertises


      i bought this to go along with my PN58C8000 Samsung 3D plasma TV and purchased it because I heard that this TV although looks great buzzes sometimes. But the BB sales guy said the buzzing is generally from the dirty power being passed through to my speakers and a proper surge protector would filter that noise out. Well after purchasing this surge, I have noticed that the buzzing has decreased significantly (I can still hear it sometimes but it is very less audible) But the reason why I love this Panamax is because it has also improved the picture quality significantly. I can't tell you how watching 2D on this TV can really make it still pop out to create a pseudo 3D effect. I love the design of it, it looks heavy duty and compliments the entire home theater. On another note, this thing is really expensive! I can see a novice home theater purchaser would be overwhelmed when being told that they should purchase a $700 surge protector after they are already dropping $2K+ on a TV on top of that. Especially when you see other surge protectors that claim to do the same thing for about half the price. But honestly, if you have the $$$ to drop on a $2K+ TV, this is a worthy investment. But it doesn't take away the pain of having to fork $700 over lol!

      Top of the line power conditioner

      • My Best Buy Premier Silver MemberElite Plus Member

      I have never owned a power conditioner before, but after doing a lot of research and asking some friends who are electronics engineers, I decided that a power conditioner was some of the cheapest insurance I could get. I borrowed a special meter to measure the power on my old system, and the transients were crazy. In plain words, the power was dirty and the voltage varied much more than I ever thought it did. Perhaps that is why my old TV was having problems after 19 years. The same meter was used to measure the output of my new power conditioner, and it is quite a difference. The power sine wave is much smoother, and is remarkably constant. I know many people won't have access to this type of measurement equipment, nor do they have the technical knowledge to know about this. Bottom line is that I now understand how important this is to extend the life of sensitive electronics. I bought another one for my computer system. This is the reason I bought the 5400.

      Audible buzz kills this product

      • My Best Buy® Elite Plus MemberElite Plus Member

      I've owned the Panamax 5100 for three years and have never had a problem with it. It runs quietly and has protected my equipment through numerous storms. I recently significantly upgraded my stereo equipment (MacIntosh 7900 amp, B&W 803 Diamond speakers, MartinLogan Balance Force 212). Since I had nicer equipment I thought I would upgrade the surge protector, so I chose the Panamax 5400. Big mistake. My 5100 was dead silent and reliable. The 5400 buzzed loud enough for me to hear it from twelve feet away. That's with the second bank of devices switched off. When I switched them on, the buzzing doubled. Absolutely ridiculous. I'm going for sonic purity and absolute silence between tracks. I don't need a constant buzz muddling the crisp vocals. This device is going back as soon as I can swing by BestBuy. Sad, because I liked the idea that the surge protector was managing the power flow.

      Protect your electric

      I replace 5300 with the 5400. 5300 worked great for 8 years. I had at less 3 brown outs. In that time frame. The last one did it I replaced it with a better one. Both of them give me a better pic. And knowing my equipment is protected. My opinion it'seems worth the money when you can pick it up for $500. I also wanted to see if there is any difference from 5300 to 5400. Still thinking of sending the 5300 back to Panamax to be fixed. Reading low voltage alarm stays on. For now I love 5400 not seeing much of a difference from the 5300. Both work great. Hope to get 8 or more years out of 5400. Cheaper then buying new equipment. All of my electronics are 8 years old. I do believe it's helping to keep my devices healthy.

      I purchased this to protect my HT equipment. Also, to improve overall picture quality and sound. This product certainly did the trick. Great investment and protection. Im also thinking of exchanging this for the model below 5300 cause the only difference is the voltage regulator feature which in my area i wouldn't need it. The only time you would think of getting the 5400 is if your area has really inconsistent or huge fluctuations in power running through your home. Your voltage in your home should be consistent at around 120 Volts. Also, save some money. So, I would consult with a electrician or PG&E to see if you have that issue. Other than that AWESOME unit. I'm thinking of buying another one. LoL!
