Headphone amp?

I use a Woo WA22 tube amp with my HD800s, and I think it sounds great.

The signal is run balanced with XLR connections from a Sony XA5400 SACD player. 

With the ability to roll different type of tubes you can tailor the sound.

Pass makes a good headphone amp, as does Luxman. 

Hi there OP, 

I have experience with vintage gear and the 6.3mm out for headphone listening on those units. The sound is fuller than something like an M-Audio interface, for example.

I heard that the A 30 Pro from Topping is really good. Lots of reviews on the internet. But I have yet to to try it out.

I also have the Quicksilver Headphone amp.   It is awesome, built like every other piece of Quicksilver gear....like a tank.  It is high quality and sounds great with any impedance phone.   Its killer for the $$$    I had mine built with a chrome transformer cover like my Mid Monos.   

Do you people listen to your equipment or to music??
