Best kept secret in AC line filtering conditioning

Be aware that the Puritan 156 has filters on every outlet and may not work well with power amps (and integrateds) because of "current-starving" under dynamic conditions. Also, the 156 uses gas discharge tubes for surge suppression. The problem here is that GDTs take several microseconds for the gas to ionize and let-through voltages in this interval can be very high.

IME, any power conditioner using filters to shun the AC noise and fluctuations is a compromise. Not only filters restrict dynamics, they also ‘color’ the sound of your system. Some may prefer this coloration (some may call it fine tuning of AC) but you’re not hearing what you’re system is truly capable of when it’s masked with such colorations.

The simplest and arguably the most effective way of AC power conditioning is by way of using a balanced isolation transformer for your system, where everything is plugged into such device, including your amps.

No loss in dynamics with two monster SS amplifiers used on the 156. No speculation here, but actual experience. One is a pure Class A 60/watts per channel by Clayton and the other the #8 Coda powerhouse amp. Both sounded better plugged into the 156. No loss in dynamics whatsoever.

These units do not limit current as advertised. 

Oh this post's title got me.  I kept ignoring it but finally read it.  I've heard a lot of power conditioners, as in literally heard them.  If the power coming into your house was dead clean, then adding almost any power conditioner would be detrimental to your sound.  I've only heard one power conditioner that improves the job of source equipment, helping power amps is what most aim for, but unfortunately this unit comes with a hefty price tag because it also has circuits for power amps.  I bought an Audioquest Niagara 7000 just for what it does for my source equipment and wasn't going to use it's AC outlets dedicated to power amps because I didn't want to risk my power amps influencing the power to my source equipment.  Before buying the 7000 I held out for a year hoping Audioquest would offer a stand alone version of the 7000's source equipment section without the power amp section, but sadly, it wasn't on their radar and I had AC issues with my source equipment that I wanted to be rid of so I bought the 7000.  And no, the model name isn't the price of the unit...It's much worse than that.  It cost me a couple grand more than the model number.  Ouch!!!  But it was actually cheaper than the quotes I received to rewire my house AC power for the audio system.  I did finally connect the amps to the 7000 despite my certainty that it would mess up the "source AC nirvana" that I had invested in.  I was wrong, I can't hear any difference with the amps connected directly to the wall outlets or through the Niagara 7000.  For that I was pleasantly surprised, but I still plan to feed the amps AC from their own dedicated power conditioners so I can crank it up.  So I am either going to buy each amp their own 7000 or anything I can find that sounds better than plugged straight into the wall.  I would like ones that sound better than no conditioner at all, but so far, besides the 7000, I've only found ones that sound worse than nothing at all.  I am very interested in this "Best kept secret in AC line filtering conditioning" but open to other suggestions.  I love my amps because they are so dynamic but that is also why they are such a total pain in the Ar$3.  They trip 15 amp breakers if I have them cranked up and a particularly loud track comes on.  They are ridiculously power hungry so I am sure that I will need 2 more Niagara 7000, a left channel and a right channel plugged into their own dedicated wall outlet, or maybe 2 of the " Best kept secret in AC line filtering conditioning" to keep up with their voracious appetites.  Any thoughts?
