XLR to RCA Adapters

If you are confident you want the combination, keep your single ended cable and just have the ends going into the amp reterminated with XLRs. it obviously will NOT make this a balanced setup...but you wont have to fuss with adaptors. i have a CJ pre and a Gryphon Antileon amp (balanced only)...and i just had my Transparent Ref's reterminated at one end. i had been using Neutrik adaptors provided by Gryphon...and they seriously encouraged me not to use them long-term. After finally getting the CJ pre i wanted (and being confident i am keeping it)...i got the cable reterminated. good luck

If you are going RCA to XLR because you like the 2 components, then many people would say reterminate your RCA cable on one end...in order to get rid of the adaptor.

As for SE vs Balanced, yes many people feel there is inherent superiority of Balanced over SE technology...however, as with many things in life...it comes down to execution. A well executed SE will still sound better than a poorly executed balanced.
