Garth Powell on Why Audioquest does not make AC Regenerators

When I purchased and installed my first AudioQuest Niagara 1200 conditioner (with an AudioQuest NRG4 power cord), the improvement was immediately apparent. It took no time to determine it was a worthwhile purchase.

Prior to the AudioQuest, I had owned or auditioned Shunyata, Synergistic Research, PS Audio, Bybee, CorePower and Alan Maher power conditioning products. They all produced some degree of positive change, but none were as dramatic as the Niagara 1200.

I hate to be a PITA but in a controlled AB test I seriously doubt anyone would hear a difference with any of these. If you can tell the difference then one or more of your pieces has a weak power supply. You should identify that piece and replace it. Can battery power supplies be useful? Sure, in very low level power devices like phono stages where noise levels are critical. Preamps maybe. Amplifiers get more complicated and I think the power supply of the amp should be purpose designed to run with a battery. As a example, large capacitors are not needed at all. The battery is in reality a huge capacitor! It's power just has to be regulated. An amplifier would require a lot of battery which is probably the reason it is not done. Channel D's phono stages are run with auto charging batteries.  
@tvad, $1K for a 7 outlet power strip is pretty steep. I got a real nice 10 outlet one for $54.00, with yellow outlets no less. Very cool.

Before encouraging, suggesting, or demanding a blind test why don't you just listen these devices produce definite, measureable, repeatable differences so I am not sure what you're problem is of course all of you're equipment is "perfect" I am sure! 

Y'all going to provide that measurable repeatable documents or you just bustin on Mijostyn because of what he wrote. I would certainly like to see what ya got to back up your statement. I think everyone else would too.

Very cool indeed. I have read your comments over the past couple of years. You appear to have a very nice, carefully assembled system. Congratulations.

I have been an Audiogon member since 2003. I generally try to be helpful. I try only to mention and discuss gear I own, or that I have auditioned. I have good ears. My early professional career was partly built upon my listening skills and hearing acuity.

This site was once robust with useful discussion about audio from dozens of active audiophiles. Members shared experiences, and yes, sometimes discussions became contentious, but there was seldom the level of nastiness that exists on this site today. Most of those members have long stopped participating.

I spent nearly two months in early 2020 deleting every comment I ever made over 17 years: 10,000+ comments and 84 threads. I decided I wanted to wipe my Audiogon history clean. Yet, here I am. Participating. Trying to find some value in the forum content. There is some.

It’s hard to generate enthusiasm to continue contributing when I read certain comments. Yours is a perfect example.
