anyone compared the hydra vs aR6 vs magic stealth

I use a PS Audio Power Plant Premier on my source componets and TV and the Hydra 4 on my power amps which draw a lot of continous wattage.

The Hydra seems to lower background noise some and lets a 20amp's 2400 watts through unrestricted which is waht I needed on the dedicated 10 awg line.

I haven't tried the others but am very satisfield with my current set-up.

I went from a Chang to a BPT-2... added an aR-1 just for giggles... and based on what the aR-1 did... I purchased an aR-6. IMHO the aR-6 is absolute magic. I now hear layers of voices where before I thought one person was singing.

I own the Stealth XXX, and there is NO current limiting or voltage lag with the unit, RE: My two main monoblocks (tubed/110wpc) and woofer amp(SS/255wpc). I've been very satisfied with it's performance/the lack of background grunge resulting from it's addition to the system.
