I've had the MF DAC II for a while how, now I hope it's not my hearing,but over the last few days sound I enjoyed has gone. I like precise, detailed and fluent sounds. Every time I play a tune it sounds distant, almost like it has a very slight reverb, muddled in some places certainly not that accurate.
