I am sure it sounds fabulous if the A8 and A16 are anything to go by... I have yet to hear one in person however, so perhaps someone else who owns one can comment?
Ive been usiung it for a while and it is good. sounds better than the ones in my old tascam tmd1000 and seems to be comperable with the adat xt. certainly they are good clean and the multi colored leds work pretty well. . .
