I had both. They were not even close. The Hydra "changed" the sound of my system but did not improve it. In my system, the sound application RLS-1 was nothing short of amazing. I have had a few other conditioners that all alter the sound in one way or another. Some of these changes are pleasant. However, I always found that something else would change for the worse (i.e. lack of soundstage depth, unfocused images, oversized images, etc). The sound application changes things the least. For me it improved soundstage depth and preserved focus of images all with glorious timbre. One caveat. I recently changed my entire front end and found the the Adept Response AR6-T was better with my new front end than the sound app. Thus, all of these things are system dependent. If there was one message I would leave you with it is that the sound app puts the least of it's own signature on your system versus the others.
