Hmmm: I listened a SF CD player a while back. I did not give it too much attention as it was way out of my price range (even used). I did not find it to be thin or cold at all. The speakers in the demo were Linn's and I did not pay any attention to the amp/preamp, they may have been Plinius, but I am not certain as the shop has quite a few combinations on a switch box. People have certain expecatations when listening to a tube unit for the first time (they expect it to sound tubey). Audible Illusions L1 and various AR models do not sound tubey, but they do sound musical.
Sonic Frontiers Preamps - Cold & thin?
In reading reviews on SF preamps, there seem to be two camps: those who think they are among the best tube units out there, & those who think they sound analytical, & thin in the midrange & treble. Would like to hear other's experiences & how they would rate them against AR & CJ. Also, how does the SFL-2 compare to the newer Line models?
