Couple things i need to correct myself on. 1 - I said it heats up in USB DAC mode with laptop... it actually doesn't, like at all after several hours connected to my laptop watching tv. It must have been beforehand when i was messing about transferring songs and settings (tho it still was hot to touch). 2 - After concentrating solely on the M6 for 2 days it does actually have some decent weight in the sub bass, so i take that back. It's not super deep but still more than adequate... mid bass does still have bit more presence tho.
Good! Yeah in time things do change. There is also this thing they call.. burn in? when you have to get used to the sound (cans/amp/dac) so your ears fully "understand" it.
