I would go with Cardas at the price level of about 10% of your average component costs. Sounds like you want to be careful not to get cables that are too “hot” of it’s honing to get fatiguing. Cardas will add refinement. Alternatively, try DHLabs at your price level. I use Transparent, but have very refined equipment which I want no change to the component sound… so Transparent are it for me.
It is always advantageous to compare about three brands and see which is most complementary. The cable company has a lending library or you can borrow through dealers or purchase. I have a few sets acquired over the decades allowing me to compare for their house sound… then if one is good… I’ll buy new upgraded versions. I also lend them out.
