I am thinking of buying a music hall dac 25.3. It looks ok, not that bad. but there is very limited info about this DAC/AMP. Can anyone who have some user experience tell me the improvement this little machine can give me? I planned to use grado 325is with optical wire on computer (desktop) flac, ape files. Any ideas?

Thanks for the ideas!
