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).

On the true balanced, I don't know. That would be a question for Shunyata. Email them on thier site and they will let you know. I don't use balanced. Some interesting threads on AK about how balanced is not good or something, I don't understand it but the equipment and the i-connect aren't matching correctly. Seems many are having problems with balanced and get better sound out of single ended. Don't know all about it and don't understand it though.

I am very surprised to hear you think that there are cable manufacturers who sell cables that are not balanced internally but are sold as balanced with XLR plugs. Can you name one instance where you have experienced this, or know it to be happening?

In balanced designs it is appropriate to sum the two signals into one and then split them again, at various points in the chain. This is how noise is cancelled by using balanced circuits, and it is a misconception that a fully balanced system keeps the in-phase signal separate from the out-of-phase signal throughout the audio chain. Splitting and recombining is part of the process and can be seen in top of the line Pro gear, as in domestic audio gear. It is true that some equipment is entirely single-ended and merely uses an inverter to split at the output to provide a balanced interface for cables. This is not inappropriate. Yes, it means there are no benefits of balanced operation within the component, and yes there is an added active stage on one leg at least, but having balanced drive on the cables can have its benefits. There is no simple and single right way to use balanced topologies.

Redkiwi, thank you very much for your comments.
You will most certainly never hear me say that some manufacturers apply XLR plugs to unbalanced cables and then claim they are balanced designs. However, I have read several times (including older A'gon threads) the simple statement that XLR-finish is not synonymous with balanced IC. Given I sometimes see one and the same cable offered with RCA-to-RCA, XLR-to-XLR or RCA-to-XLR at the purchaser's choice, it looked wise to explicitly inquire about the topology of any XLR-cable. Any additional thoughts from others posters on this?
I have no first hand experience, the Ayre-combo would be the first gear I'd like to use balanced IC's with. Which is precisely why I'd put a few big fat exclamation marks after the last sentence of your second posting as it summarizes the reason for my original question: Do owners of the same gear think it is wise/worthwhile/indispensable to go balanced. And then one more: Of the many brands and models available, which one seems the most rewarding, the most "right" if you want.

Well, I ordered an Origin Live Silver tonearm in a balanced configuration, and simply got a tonearm with single-ended cables and XLR connectors. Yes, the shield was used as the negative lead. Therefore, due to the noise picked up from the shield, I cannot run my Ayre P-5xe in balanced mode - the very reason I ordered the tonearm whe way I did.
