I switched my HD 7 interconnect on my sub for an XLR2 because my new Pre has XLR. All I can say is that it is a huge improvement in tightness of bass, volume & defenition. Not saying the HD7 wasn't good - just the XLR obviously suits this component set-up. I actually needed to turn my dial on my sub down from 11 o'clock to 10 o'clock. Absolutely amazing!!!!,
