Everything Bhouser said above is correct. I own the original version with the (off-white) outlets and a friend of mine has the Hydra 8. We are going to put the two side by side in the near future to see what sonic differences exist. I've heard from some sources there are a few, but not enough to make me want to throw mine on the Gon. It works beautifully in my system, that's for sure.

I'm looking to purchase a used Hydra power conditioner. As I understand there have been 3 versions produced so far, the latest being the new Hydra 8. Would appreciate if someone could enlighten me on the difference between first and second series of Hydra's and how I would be able to physically differentiate them (where possible). Thanks
