Best interconnect between Ayre AX-7 and CX-7

Time for another change in the second system. I found a few months’ old Ayre AX-7e at a bargain that I’ll pair with my Ayre CX-7. In every review of the AX-7 I found, and especially when looking at it together with CX-7, reviewers have praised the superior performance of balanced interconnects. Sadly, mostly without mentioning the IC’s used.

I read through a few older threads on interconnects for Ayre gear as well as the (disputed) general merit of balanced IC’s, particularly over short lengths. And was left a bit puzzled as to what the views expressed there would boil down to for this particular pair of machines.

Can anyone lift the veil (… or add to the confusion) what IC’s would bring the best result with this gear? In case Stealth Indra leaps to your mind, I am rather looking at something in the $ 500-600 range here (between 0,5m and 1m length, new or used). As far as XLR’s are concerned, I have seen a pair of Acoustic Zen Silver Reference II that would fit the bill, but would it fit sonically? (I have as yet not received an answer from the German distributor as to the availability of Ayre’s own IC’s btw, so I can’t judge their price level over here.)

As always, many thanks in advance for your thoughts or recommendations (XLR or RCA).
