I agree with Sean. I had a Power Conditioner rated for 1875 watts at any of its 16 outlets, and it worked quite well when I had less resolving components. But it always caused a "thin character" in music along with a reduction in dynamics when I plugged my McCormack DNA-2DX (300 wpc, 8 Ohm)into it.
As the quality of my components improved, and I installed a dedicated AC system, the Power Conditioner became a distinct liability, and I finally sold it and plugged everything directly into dedicated outlets. I asked Steve McCormack about power conditioners, and he just flatly said "plug your amp directly into the wall". Good Luck, and Cheers. Craig
