After many tests this is my current system, in short, the powers change Krell KAS-2, by Krell CX-700, which by performing extensive tests are truly extraordinary in every way! never heard something else comes close! I get over my ears to other models of the brand as FPB-350/FPB-750, KAS and KAS 2 and other brands also evalue , Pass Labs XA-160.8.De of here a couple of months I hope to have them installed.
Heavenly Krell's angels indeed. Look forward to other chiming in on the discussion of power cords and such. At this point I wonder if more bang for the buck would come from other tweaks. Enjoyed seeing the pictures of your system. Happy listening. Glen
