Definitely add Acoustic Zen to your list. If you bi-wire here’s a nice pair of their Satori cables at a great price and think they’ll do just what you’re looking for, and if they don’t work out you can easily resell them for maybe even a small profit. I’d also highly recommend their Silver Reference interconnects that are very neutral/natural sounding and their Matrix Reference II that skew just a bit warmer. The whole AZ line has a very natural/organic house sound that is cumulative the more cables you add. Just another option, and best of luck.
