I'm getting rid of my audioquest diamondbacks. XLR on the amp end RCA on preamp 1.5m I connected a pair of Audiometallurgy GA-0 .5M to my Linn Kudos Tuner and they sounded great right out of the box. I got another set of .5M for the EQ to Preamp, and I'm waiting on a 1.5M set w/RCA's for the Amp to EQ. They are great sounding and very reasonable especially if you win bidding. Happy listening.
