That said, since he mentioned a neutral to warm sound, I’m not sure Morrow is the right option. I’ve got some of their MA 5 interconnects and warm would not be a descriptor at all.
this is the previous silver coated copper design though, their current line is all copper. I haven’t seen many owner reviews on the new stuff and none calling it warm.
Cardas cables can be warmer, and I think some Audioquest. I’m not sure it’s worth it to spend that kind of budget though unless the amp/speakers are several thousand each. YMMV.
