I'm using 5' Cardas Clear Lights from the preamp to the high-pass and 7' Clear Lights from the high-pass to the amp. The sound is excellent. I'm going to try substituting 6' and 10' Mogami 2534s, because it would make a neater installation, but I don't want to reduce sound quality.
Cardas Clear Light or Mogami 2549 XLR
The setup I'm putting together is XLR from an Ayre KX-5/20 preamp through a Marchand balanced passive high-pass crossover to an Ayre VX-5/20 amp. The impedance of the crossover is 1K Ω. I have the Cardas and Mogami cables. Either preferred? I've previously used 3' Cardas between the preamp and amp, but these are 7' cables.
