After many years of various speaker cables, I’ve settled on Analysis-Plus Solo 8 copper crystal. Straightwire Crescendo is very good, slightly warm. And XLO Reference 5 a great used bargain but quite stiff. I own and use all in my systems. The Harmonic Research Pro 9 , 9+ is neutral and deserves mention as well. All can be found used but for less than $1k. which is where I "play".
There are definite synergies in systems.
