I have a Roksan K2 and think it is a superb amplifier. It has a firm and well controlled bass, a detailed mid band and treble, and seems to really draw you into whatever music is played through it. I also use the K2 power amp in a bi amped system which gives an even more expansive sound stage and effortless power. The inbuilt phono stage is pretty good too, very quiet and detailed.
I would thoroughly recommend it, although ultimately you should hear it for yourself. My wife and I auditioned it against the Marantz Pearl Lite, using our own Musical Fidelity A3.2 CD player and some large KEF floorstanders and it was obvious to both of us that the Roksan had a sound that gave more insight into the music, more 'emotion' if you like!
