The best speaker cables you’ve had

I use OEHLBACH XXL Fusion Four.
They don't "sound" at all but are well made and quite stylish.

I had MIT, Transparent , Luna. The latest I got was Transparent Ultra. It made the sound much closer to live studio than anything I hear before. My dealer (not sellingTransparent ) was also shoked. I got them used , bi wire.

Transparent  reference xl.  Not dire there is anything better out there 

Sure  not dire

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.
