Here comes another awesome review on Calyx Femto DAC from Magazine-HiFi.
Some quotes from the review :-
"I admit to hesitating for a short while before finally admitting that this is the best DAC we have had in our hands so far." "To get back to music and the Femto, and thinking only of the brass and the piano, I’ve never had the chance to hear anything like such rightness of timbre and associated dynamics on my sound system. " "The only thing you really have to know about this converter is that it respects musical sound, or at least that it delivers the goods without artifice, without artifacts… the music, just the music. Whether it’s from my laptop or from the CD player, the DAC’s musicality came through, and at the same time I rediscovered P.R.A.T (Pace, Rhythm and Timing): I was tapping my foot to my favorite tunes." "The Calyx Femto DAC has to be heard in your system at least once. You’ll never hear its sounds the same way and it will open the door to the possibilities of tomorrow. The digital medium has never been closer to convincing me it’s mature."
