Thanks for all your help on this thread here.
Can you comment on the noise floor of X3?
How "black" is the background when using low impedance BA IEMs? AK100's are known for how silent they are, and was wondering if X3 achieves a similar level of low noise floor.
I know for a fact that AK100 is extremely clean in noise floor, but the trick they did is not to implement any actual gain stage (or amp stage in the matter) as you would do in a typical DAP. It is a claver way around the problem but also has problem of its own (lack of power, for an example).
Anyway, I should begin to gather all my thought / previous impression and hopefully the review will be posted by weekend.
