The best powercable for power amps?


I hope to find the right powercable for my Nu-Vista 300 poweramp.

My system: Nautilus 800, Meridian 800 DAX v4 ( model 2005 ), Musical Fidelity Nu-vista 300 Power, Valhalla loudspeakercable, 2 Valhalla powercables, Acapella rca, KE Powersource ( conditioner )

I was thinking about the Shunyata Anaconda Alpha, Elrod, Purist or......

Just give me the right advise for the cable what can give me the whole freq. spectrum van the lowest to the highest?

I used the following cables: MIT AC-1 Oracle, I liked this one exept it missed the lower freq. Valhalla, I missed the focus and didn't like the harsh sound in the low freq. Also the mids where not involving anymore. The Electraglides miss the power in the low freq also.

Hey: I'll chime in on the powercord issue. Marigo Ultra 4 cords in "K" or "T" tuning types. Tonally, fundamentally, musically, the best I've heard-and they really piss-me-off cause they should not whomp the Shunyata King Cobras V2's I use (but they do!). Anyone, and I mean anyone whom is auditioning super-HI-end power cords should audition these in their system.
TRANSPARENT mm models, they are the current version are my recommendation. Worth the price. You have a very good system. Try refernce or refXL power cable. They rarely show up on Audiogon, but I have seen them.
Good listening,PH
