Yep, I understand that and honestly they are not really noticeable unless you pay attention. However, I think it may be possible to reduce or eliminate the 3-4 clicks when starting up/jumping in the track via software/firmware since it seems that the system is the one that seem to be resetting the internals. As for the clicks when you turn the dial, that is unfortunate but not a major issue.
As for the sensitivity, I hope that in the v2 of iDSD, there is a gain switch. Right now on the Shure, between nice to uncomfortable loud to painfully loud is about 15-20 degrees turn of the knob to reach the next level. On my Fiio X3, I would need to go, on low gain, from 15-17 to 23-25 to over 30. On such a small knob, it is quite tricky. Furthermore, the iDSD is using the 3.5mm plug which is meant for portable use thus IEMs with the sensitivity like Shure is expected to be used together with the iDSD.
Don't get me wrong, I'm quite happy with the iDSD, but these issues should be looked into and refined in the next version of the device.
