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

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?
Replaced a PS300 and HC Ultimate Outlet (now in my second system) with a Hydra 8/Python Alpha rig. I had the opportunity to try a RGPC 1200 and a Tice unit in my system and neither performed as well as the Hydra. I've heard the BPT 3.5 in another, more expensive system but the results weren't ear-inspiring. The Shunyata gear stays, I'll focus on other upgrades.
