Of all the cables that don't make an objective difference, interconnects are those but what absolutely does make a difference is expectation bias.
RCA Interconnect recommendations
I'm looking for a new set of interconnects and need recommendations. I'm running a Rega P3 (with Exact and Neo PSU) and a Sonic Frontiers SFL-1. In between, I will be adding a Darlington MM7B, which is on order. I was using an old pair of Cardas Ultralink 5C interconnects but find them a bit muddled. I also have a pair of Audioquest Red River interconnects and they're very bright. Any suggestions for something that's musical, clear and detailed, with good bass response?
