Sunrise Project Amp, what is SQ like?

I'm currently testing one of these babies :) Sound Quality is great but it need a good source to be at his best... if you want more info on this you can look on the DIY rockgrotto forums :

pros:

-it's more versatile than the bottlehead crack since it's not OTL but hybrid design : it can drive my AKG K340 with authority, even AKG K1000 or Hifiman HE6, it's a perfect match with Beyerdynamic DT990 600 Ohms, it must perform well with grado if you use it with a tube not too sharp in the highs..

-I found the sound quality of the Sunrise better than my 400$ Audio-GD C-2 + OPA Moon : more Powerful, wider soundstage, more nervous, and a great "tubey" sound :)

-Easy to build even for a beginner (look at the manual:http://www.garage1217.com/CURRENTSUNRISEMANUAL/), you can order it with differents options, even built : http://store.garage1217.com/project-sunrise-hybrid-class-a--tube-headphone-amplifier.html

cons:

-need a good source, with a REAL lineout output (2V), no DAP or mp3 player...

-output can be slightly noisy, with low impedance phones at very loud volume the background is not "dead silent"
