Transparent Cables interconnects question

I can't tell you which sounds better because I haven't listened to them back to back. 

I prefer balanced connections because of the increased signal level and the lower signal distortion.  

I'd try to audition them back to back if possible.

Both components have balanced connections. One is a Krell integrated, the other is a Rotel cdp, but not sure of the model; I believe it’s a 1570. I’m posting this query for a friend who advised these two interconnects are for sale somewhat close to him (two different sellers).

Rotel is generally not a balanced design, only offering XLR as a convenience, therefore no electrical advantage, though some believe XLR's offer a tighter connection...

Unfortunately it is not a question of if they have balanced connectors, it is a question of internal design. So if one of your components Is not balanced it is difficult to tell… I would go with RCA. Some day when your components are much better, it may matter and in the mean time you have more money for components. 

So we spoke with transparent and confirmed the info indicated above. They said to find out which connection type is native and then choose a cable from there. If one is native to xlr, and the other rca, then best to test both option to see what sounds best. Also, my buddy’s cap is a Rotel 991, not 1570. I gotta say though, the more we were discussing transparent cables, the more I was gaining interest in them myself. My current cables are harmonic tech pro-9 biwire and pro-silway II xlr. I’m using them with a levinson 383 integrated, ayre cx7emp CD player and revel f30 speakers. I don’t see much written comparing these two cable brands. Anyone have any experience there? As for my buddy’s system, we need to contact krell and Rotel and see about the native connections
