NBS cables were very highly thought of and pretty expensive though I can't admit I've heard them. Like as not they give up little or nothing to "today's technology" but only auditioning can really tell you. Maybe contact The Cable Co and spend some time auditioning various cables?
Cable thoughts
Looking for Opinions. I'm using a pair of NBS Monitor IV XLR that date back to early 2k's. Bought them used way back when. I'm considering purchasing a set of Transparent Audio Ultra XLR with original mm1 technology, not mm2 or recent gereration 5. The price is pretty good BUT I don't want to go equal, slightly better or backwards. Just looking for some thoughts. I know at one time these were nice sounding cables but not sure how compared to today's technology. I also am using a pair of TA Super xlrs mm2 from my Ayre Codex DAC to Proceed AVP 2+6. Most of my gear is old but I love it and it still sounds great. Looking to economically upgrade thus I'm financially incapable of buying the latest greatest.
