RamakaSure, plenty of power here to drive the 650s.
But IMHO you'd have to roll some tubes and do some mods in order to get decent sound quality.
If you can afford to, get a Schiit Lyr instead.
PilotChuptoo much noise without some modding, did you try them? my HD650 say otherwise..
But after a few power-related mods and tube rolling, the Bravo is actually a pretty good match with almost any high-impedance headphone.
