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.
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
