Ah man, it's hard to get the kind of answer(s) one is looking for here nowadays.
I do appreciate that members do take the time to offer up answers and observations, but I really do question the legitimacy of some of those responses.
I frequently see responses like the one from gdnrbob saying "IF your equipment uses the AES standard, then XLR cables should have minimal effect on sound quality." I currently have 4 pairs of balanced interconnects, Moon Audio Silver Dragon, 6Sons Audio Golden Eagle, Grover Huffman Pharaoh, and some older cheapo professional cables. They most certainly DO NOT sound similar, and they have a very significant effect on sound quality. Now, if you've experimented and tried several different cables and found your statement to be true, would you please reveal what those cables were. Also, do you find unbalanced/rca interconnects to sound generally different or do they sound relatively homogeneous as well?
I also find a concern with electrical conductivity with regards to sound quality to be
largely misplaced. The Oyaide 004 AC plug's outermost plating is platinum and that is rather less conductive that silver, gold, copper, rhodium and most anything else you'll see in audio but, the 004 kills every silver, gold, and copper plug I've tried by being more resolving and neutral and just about everything else I value in my audio system. YMMV of course. What matters is sound and I'm looking strictly to those who have direct experience with the xlr plugs mentioned. If any of you have experience with the Neutrik silver or the DH Labs vs those mentioned plugs, I'd really like to hear about that. Thanks again for taking the time to respond
