I've lusted a bit after the Hyperion from SS, and have a Sussurro MkII which is the cartridge just below the Hyperion in that product line. I find it like the Grado Statement 3 - honest, thorough but unexciting. I won't bore everyone again by recounting my purchases of all the MI carts I could find when looking for a replacement for my Deccas. I'm coming to the conclusion that the involvement/excitement that comes from the Deccas is either a very discreet but addictive distortion they impose on the music, or maybe some subtle improvement in timing and responsiveness that makes them seem so real. I doubt if such can be measured, but my ear discerns it.
The cantileverless technology of the Deccas is about to become extinct as John Wright retires with no successor, and the company that made the armatures is no more. I'm hopeful the reduced moving mass designs relying on a strain gauge or an optical detector will simulate the agility, responsiveness and liveliness of the Deccas.
