Shunyata Hydra


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

Thanks everyone.

I wired three independent armor shielded 10g – 20amp circuits to my A/V closet where all my gear is. I don't have a lot of stuff (minimalist approach), but I figured one circuit for the front power amp(s), one for the sources & pre/pro, and the last for the rear and side amp(s) [this being a home theater and listening room].

I am still trying to figure out the differences between the various shunyata hydra models currently offered other than the number of outlets, and their respective prices. However, maybe all I need is one, and run everything through it.

I used to have the Hydra 8 and have had the PS Audio P1000 and now have the BPT 3.5 Signature. The BPT is so much more quiet and transperant than the other two, it really is in another league. It is by far the BEST PLC I have ever had in my system. I could not be happier.....I even have my VAC amp plugged into it. I draws 500W a channel and I finally have no limiting of dynamics that I noticed with the Hydra and it does not add anything, like I noticed with the PS Audio.
Balekan, thanks for the input. I recently saw that ZCables is packaging the BPT with their power conditioning sleeves. I may investigate that one based on your comments. I tried both the hydra and PS Audio and both made my system sound different but not better.
I have everything plugged into the Hydra 8. The difference from other is that it seems to relax any glare and produces better dynamics. I have had the Ps audio and Tice and sold them upon hearing the 8. It makes an unbelievable upgrade
I ordered a Hydra 8 and I am being told it comes with no power cord. I thought it was supposed to come with a Diamond Back power cord, what gives?
