I found the coloration to be enjoyable on that rig. I wouldn't trade my gear for it, but it was still enjoyable, especially with the pop music they had available to listen to.

Would I use it to listen to my favorite classical pieces? No way.

I wouldn't listen to Godsmack, Michael Jackson or Daft Punk on it.  Too compromised for me.  I seriously don't get it. 

I don't see how the coloration on the HD800 would be acceptable from the Bakoon amp, but not from the Eximus DAC which I know Marv hates.  I think if you buy into one as okay, you have to accept the other.

We can agree it's not a Leben.

OJ, go pick it up from burn and see for yourself.  If you can come back and tell me with a straight face, the HD800 is technically superior sounding in current mode than it is in voltage, I'll let you win the internet.

I wouldn't listen to godsmack on any system.

I did enjoy some Beyonce on there, though.

I think the Questyle cma800r uses current mode output. While Marv here didn't like the sound of this amp very much (too boring?), I think enhances all the strengths of the HD800. In particular accuracy in details extraction, imaging and staging, which happenens to be my favourite thing about the HD800. It doesn't add anything to the tonality, and some may want some extra bass in the HD800. I haven't heard many high end amps so that may be an factor here, but I think the current mode in the questyle is done very well.

The Questyle CMA800R has voltage input and output but internally they use current gain circuits.

Ah, I didn't know that! Thanks for the info!

I can understand why some may call it boring, but for now I like it. Not gonna lie, a future fully balanced ygg/rag combo sound really tempting 

Sorry for the off-topic!
