I have personal experience with Crystal Clear Audio. Small one-person operation in California. Solid performance, but practically no resale value. Make sure if you buy, you pay half of the “advertised” MSRP. Other than that, they sound pretty good, and good build quality. I never understood where they get the “6N pure silver” conductors, if true, but yes, they sound good.
Shunyata Venom is their entry level cable. IMO you need Alpha or above to get the true Shunyata benefits. The power cords and power distributors are the Shunyata forte. Speaker cables…. Not so much
