Favorite cable brand.

Where I started and where I am today.

Monster Cable
AudioQuest
Kimber
DIY. Wire and plugs from Michael Percy and Ron Welborne
Back to Kimber
Canare, various.
Clear Days IC both single/balanced and speaker cable with Shunyata PC and Hydra
Nordost
WyWires, with still a couple Nordost and Supra Cat8. Fairly happy where things are with cables and rather spend money elsewhere in the system. Also some power cables for digital equipment from VH Audio, Kimber 8TC and Canare balanced cables that I also use to mic my drums.

Favorite today?

First off, your system and your ears are what matters.  Try before you buy and stop trying to outsmart everyone...it is way to variable to use isolated objective parameters of a cable as a definitive solution.  As for all the arguments regarding cables are cables...for the most part, they are often more similar than different but not without discernable performance variations.  For this reason I tried both Transparent cables and MIT many years ago to hear what a “ more than just cable” design could offer.  MIT has been the clearly superior performer for my ears, especially with their more recent offerings.  Once you hear what they can do in a properly matched system, it is virtually impossible to do without them!

For my system the winner of the speaker cable sweepstakes of 9 contestants was Straightwire Maestro. Interconnects became Straightwire Maestro after 7 shoot outs until I tried Straightwire Virtuoso. SACD and DAC feed the pre-amp via Straightwire Virtuoso and the pre-amp to amplifiers are Maestro. Streamer to DAC is Canare Digital. Power side is Audioquest Niagara 3000 and all noise drain Audioquest power cords.
