Latest reviewed on Calyx Femto from Audiostream.
Quoted form the review..
"..The Femto did a wonderful job playing whatever genre of music presented to it. From Nine Inch Nails to Joni Mitchel to Wayne Shorter, the Femto handled everything with exceptional musicality. Detail, transient reproduction, macro and micro dynamics, focus and ultimate resolution were in a first class category. I just could not find fault with the Femto."
