Power Conditioner for your amplifier?

The PS Audio Ultimate Outlet will do nothing for you, but I get an idea of your price range. I would look for older models of the Sound Application. It is the best ac filter of the 45 that I have tried for big power amps. I don't have such amps any longer but suspect that your ARC would have such needs.

I had two 100' run dedicated lines put in for $100 about 15 years ago.

Oneobgyn, I think there would be a substantial difference among amps and the use of power conditioners. The ARC Ref 600s would likely be too much current draw for any conditioner, but my little 8 watt Reimyo would be no problem, In fact Reimyo makes a conditioner and uses it at shows on the amp.

The SoundApplication you mention is in my experience quite good even with big amps. Perhaps not as big as the ARC 600, but I used a SA with my HK Citation 7.1 amps that drove my subwoofers. It was clearly better into the SA than into the wall.

I now have 2KVA IsoClean transformer which should be able to carry the Citation, but I have sold it and no longer used subs.

Let me reiterate. I am not recommending all power conditioners on all power amps. I find most conditioners harm everything more than they help and most conditioners probably cannot handle big power amps. I have owned 45 different transformers, regenerators, line filters, and other devices for improving the quality of the ac coming to my equipment. All but three, I found to harm more than they helped. I mentioned the Sound Application because Oneobgyn mentioned he had one. I suspect that my experiences may not transfer to others, so I will not mention others. I have not tried the Running Springs unit.

I have two B.M.C. M2s plugged into the High Fidelity Cables Waveguide power center using the HFC URR pcs to them and to the Waveguide. I have never heard anything that can compare with this.
