Clipping with Separates with change of Power Conditioner[?]

Even better consider a dedicated line from the breaker box to your listening room. Got rid of all hum from dimmers, large appliances, etc. Dropped the noise floor too. Improved clarity, inner details and soundstage.

Tomcarr - Yes you are correct. I have (3) 20amp lines wired directly from the breaker box. Oversized copper conduit with Furutech AC Rhodium plated outlets. Then of course good AC cabling to the isolation transformers. I’ve also replaced the outlet in the transformers with Furutech AC sockets and rewired them internally.

Naturally there's always better and more you can do.  This is the best I can afford for now.  But always adding little tweaks as I come across deals on things I can add. 

just to be clear, I recommended plugging into the wall to troubleshoot.  I do believe in a quality power regenerator.  but my regenerator costs 6X what your amp costs so in your price range, plugging into the wall is probably your best option.  don't use a surge protector if you can avoid it.  Better option is to unplug when lightning is in the area.  Surge protectors don't always protect you or maybe usually don't protect you.  but they give a lot of people peace of mind (perhaps undeservedly).  

Also, as for a dedicated line, you may already have one.  You have 3 outlets in the room you think are on the same circuit.  open the breaker and see what else de-energizes.  if there is nothing else on the circuit, then your noise level should be minimal.  If there are outlets in another room, try not to use them.  If there are lights, make sure they don't have a dimmer switch and keep them off when listening. If there are important items you can't do without that are making noise or pulling a lot of power, then you may need a dedicated line.

Harpo75, you did what I am planning to do as my house is rebuilt - put 3 20 amp circuits dedicated to listening room with  sub panel in the listening room so I can kill all power in that room during electrical storms - power conditioning for low current draw or small signal devices only. Power amps directly to the wall. Best most cost effective solution possible

What is your remaining Furman?  If it has SMP and LiFT I'd run the entire system through it.
