The Colorfly C4, although it can play Mp3's is a true audiophile quality player. No true music lover would dream of using Mp3's for high quality listening, it simply is not good enough. The Colorfly can play files up to 24Bit/192Khz which is far in excess of even CD quality (16/44). It can also be used as a high quality DAC and even a headphone amp. It can replace your CD player or record deck as a music source of the highest quality yet available in a portable machine.
I have ditched my own CD players in favour of this wonderful bit of kit. And such class too!! Hi Fi Choice have just called it 'Portable Perfection' and given it 5***** - Recommended.
