The 5A's have non-standard screw terminals. Make sure that Audioquest knows you are connecting 5A's. ..just as a friend, I have 5A's and am using all Ayre (K1xe, V1xe,C5xe). I agree that Audioquest is a good match... I think Anti-Cables is a better match. I compared the Sky and Everest to the Anti-Cables...they sounded pretty much alike but Anti-Cables edged them out..my wife thought so too. The price difference is astronomical. You might just check out the Anti-Cables before you plunge into Audioquest. They have a money back guarantee.
