I'm using Audioquest Diamonds from Dac to Preamp, and they've sounded better than anything else I've tried including most of the HT line. I have solid state amp
Bryston B60. But I did use copper from preamp to amp, a pair of XLO Type 1. I've read a some reviewers at Soundstage that concurr that this mix of silver and copper sometimes works (silver from the source component and copper from preamp to amp). I've never found silver to sound too bright or hard, but it does seem that there are differences in silver interconnects. AQ Diamond X3 can be had used for pretty cheap these days so it's certainly worth a try.
