Balanced Interconnect Recommendations

@almarg   The reason that balanced lines are going to be more resistant to noise is due to common-mode rejection so I assumed (incorrectly) that's what was underlying your points.  And yes, you referred to common mode rejection exactly in the way I meant as well.

Perhaps someone(s) on this forum who is using unbalanced circuits could do a comparison with RCA vs XLR IC to see if it makes a sound quality improvement in their system. My main system is fully balanced from input to output and I use XLR's only due to that topology.  My second system uses an integrated amp...otherwise I'd volunteer!

Real life experiences ...
I have the REGA OSIRIS integrated amp and the REGA ISIS VALVE cdp/ dac.

(1) REGA itself recommends balanced XLR interconnects between them . I stress-tested
their manual Recommendations with shoot-outs between high-end RCAs versus XLRs ....in my shootouts, REGA was right .

(2) In direct cable bake-offs in MY system (emphasis added ...) against numerous high-end brands, NORDOST FREY XLRs were best of breed at their price points.

(3) Completing the NORDOST cables array with NORDOST FREY shotgunned speaker cables and matched jumpers was a further audio performance improvement.

I would like an eventual further move up to NORDOST VALHALLAs , but budgets are always a limiting factor.

highly recommended .

@akg_ca I too have the Isis and was wondering if you could describe the sonic differences you heard between using rca’s and xlr’s from the Isis into the Osiris. Thanks so much 

The Isis is fully balanced though correct?

Yes, the Isis is fully balanced
