I ve been using thx789 for a year now with my Susvara and it actually is doing a pretty good job powering the susvara. But i think maybe the susvara could use more power than the 789 could provide as there are a lot of owners saying the dynamic and soundstage transforms to a different level when...

I am planning on getting a HD800, as they are notorious for difficult to drive/pair well I am wondering if the thx789 good enough to drive/pair with them? or I ll have to purchase another amp for it, any suggestions?
