John, so I finally got round to getting rid of the extention cord supplying a sectiopn of my stuff. Now I have 3 dedicated AC lines. Biggest noticable thing, when I turn on the amps, the lights don't blink. soundwise, .............nope. But now I don't trip over the orange ext cord. Less voltage drop by about 2 volts, by being on it's own, not on ckts loaded with other STUFF. Didn't effect teh sound at all. That could be cus' the AVA stuff is so well made, as AVA mentions, his stuff is designed to work in REAL WORLD conditions, voltage swings, I've seen on hot days AC line down to 115.....now cool out as high as 126V......Stuff sounds the same. Properly designed electrical equipment can do that. And yes 125V is nimonial, if you got 115V it's LOW!!! My PSEG transformer only serves about 3 houses, here, and it's 2 houses away, thus I get it pretty high, on 40 year old pole wire!!! Now with new service panel and service drop 200A service with lotsa space to add more stuff.Every 30 years nutin like pulling out teh rusted meter pan, yet teh meter contacts where pristine, meter socket pristine...now that stuff is in adverse enviorment and it holds up forever, PSEG won't even change the meter probably, maybe change the drop from pole to house if they think it looks weathered, PSEG dude when he unlocked the meter said, looks good probably won't need a new drop 30 years of weather!!! and a piece of wire is gonna change in your living room in 24 hours, come on Jeff....new duplex's are Leviton residental grade...box of 10 about $3...on sale. Same with the NM wire...just wire....the nonsense by the likes of PS aduio and other snaker charmers is absurdity squared. Audio grade fuses and outlets, audio grade power cords, audio grade in wall NM wire. I'm sure the PS dude lives well off the great marketing.
