I’ve listened to Shunyata Alpha and Sigmas, Audioquest Thunderbirds, Oaks, and Dragons, Nordost Odin 1, Wireworld Silver Eclipse, Tara Labs, High Fidelity, Audience, and a couple more. I own Clarus Crimson speaker cables.
The best without considering cost were AQ Dragons. In my opinion the Clarus Crimson offer the best value, coming very close to the AQ Dragons in my system.
