I made some interesting experiments. I have both a Shunyata Hydra and a Panamax. I have two systems, one music only in one room and the other a Plasma TV & theater. I put the Shunyata on the music system, then took it out and repeated. My sound was better with the Shunyata, but only a small improvement.
Next I did the same with the Panamax on the Theater. With the Panamax I could "see" and hear better picture and sound.
I put the Panamax on the Stereo and the Shunyata on the theater. I took them in and out and carefully listened. The Panamax on the stereo made no difference and maybe made it sound a tad thick and flat. The shunyata did not do much for the TV and theater but it made slight improvements.
My conclusion was the Shunyata made an improvement in sound quality on stereo and it remains in the system. The Panamax is staying in the theater and you can really see the difference on the TV.
Good Luck, and this is a "LOT OF TROUBLE" by the way.
