Speaker Cable for Avalon Eidolons

I would try several cables at once if you are going through a dealer. I found that the eidolon's change dramatically with different cables. I think that Avalon uses Cardas neutral and golden reference cables in their listening rooms. The eidolon uses cardas neutral reference internally. I tried their golden reference ic and didn't care for it. Took too much resolution away.

I'm using supra sword speaker cables with WHG, nordost quattro-fil and valhalla ic's. Note/disclaimer: I sell WHG & supra cables.
I've also tried:
straightwire black silc (fast, detailed & transparent)
transparent ultra's(quiet background, 'processed sound') acoustic Zen Satori's (great harmonics, little syrupy)
Nordost red dawn's (fast, detailed, airy, a little grain).
All of these sounded pretty good.

I plan to try out the neutral reference speaker cables at some point. I've generally found that using all wire from the same manufacturer has synergistic qualities. The valhalla speaker cable's are too delicate and expensive for my tastes.

..i would not buy a speaker cable without trying the HMS 'gran finale' cables.i compared a complete valhalla system with a complete HMS system and liked the HMS cables better.they are that good.christian brouwer is the us distributer and a great gut and gives a 30-day money back guarantee with the cables. i have encouraged 4 audiophile friends to try them and everyone of them bought them saying they were the best they had ever heard. try them..

I use NBS Omega speaker cables with great results (my amp is Pass X350 and pre is Ayre K1; I am mentioning this only because I have not heard your Accuphase which may have a different sound).

IMO, the Omegas are a great match for the Eidolons. They bring out the best in these speakers. The Omegas are very revealing though. A poorly recorded or mastered disc will find little mercy.

If you like a leaner sound or want to keep the spending in check, look for used NBS Monitor 1 (used because the Monitor series has been discontinued).
