Power Cord for McIntosh Power Amp

i have a mac amp, the 275. i recently bought a voodoo mana line cord. i like it--easy on the treble frequencies.

I use SR Master Couplers on my 501's, they are a big improvement over stock.

I used a Virtual Dynamics power 2 cryo cord - sound became relaxed with better definition.
Recently replaced the VD cord with an Eichmann series 2 cord - improved dynamics, instrument seperation and much more low level detail with out introducing unwanted nasties.
Took my 402 to another level of performance for $150.

VD or Purist Dominus for amps (in particular.) I've used Dominus for both SS and tube amps and it beats anything else.
