On the highest end equipment available maybe my 2 p20’s make 3-5% difference. What about something that makes a 50% difference? I mean night and day. Like you just went from Fisher Price to Mark Levinson. I just found it. Unfortunately it is $100,000. Don’t fret though they also make Million Dollar speakers. At what point do we stop? If there is no “stop” to be had, here it is. Interestingly this is 100% passive and regenerates absolutely nothing. It simply makes the AC squeaky clean. I have never experienced anything like this. Perhaps everyone knows about this and I am just an idiot. Explore their other “Uber” products. No offense to PS Audio, it is in a completely different category than the P20 which is already not “cheap” by any means. The P20 is very nice but this takes things to a whole different level. Most very high end gear does not benefit much from power conditioning with their very robust power supplies but here it was night and day. Just witnessed this today.
Okay, wait is over here it is: http://www.highfidelitycables.com/products/conditioner/proelite/
It is some behemoth at 178# as well!
