The Ensemble cables blow away everything I have tried including Hydra. Best part is that they are very cost effective. Give Joe a call at JC Audio (Mr Tweaker) he gave me a money back guarantee, but I kept them all!
I agree with Stealth93es. Although I haven't tried the Hydra's, I recently bought a full complement of Ensemble mega pc's, a mega powerpoint, and isolink and I'm blown away. Great stuff, and it is relatively reasonable.
