I've been looking at the Stello HP100, the HeadAmp GL with power supply and the CI Audio VHP-2 with power supply. They are all about $600. What would you recommend? Right now, I'll be using it with my HD650, but they will soon be replaced by something livelier.

I would consider the M³ too.

Can't go wrong with any HeadAmp products.
