Oh, sure, but if you're carrying your DAP in a bag, then you could carry a DAP-Amp stack, DX100, HM-901, housebrick, doorstop, or whatever
Some of us desire a high-performance DAP that doesn't require a bag or forklift truck to carry it around with!
I agree that size is something DAP makers need to be careful about, for customers who truly wish to walk around with their DAP in their pocket (and iBasso appear to have got it relatively 'right' with the DX50/90. The DX100 was just way too bulky for me to use in my trouser/jeans pocket). Perhaps you could contribute your opinion to James, re' the X7, here and here. .
Can we please drop the 'is burn-in real or B$' debate? (and the same goes for 16/44.1 vs 24/192 etc. etc. etc.)
I'm all for free speech and spirited debate, but here is not the appropriate place, as it derails the discussion focused upon the DAP itself.
It is nigh-on impossible to conclusively prove either possibility as an absolute irrefutable fact, so just draw your own conclusions, let others draw theirs, and respect each other's differing perspectives. That's...
