My favorite brand is always Cardas. Depending on your system and budget, Golden Cross, Golden Reference, Neutral Referance or Cross could all work.
Interconnects between DAC and Pre
I have a Theta GenVa and am presently using VanDenHul the First interconnects. The Firsts tend to add some color to the sound but I don't want to lose the resolution, speed et al. The digital connection between Theta transport and DAC is Illuminations D60. Any suggestions?
