Ok very quick impressions, it's fantastic! And I'm kind of past the point of new toy syndrome because I've tried so many new daps lately.
Smooth as silk, scanned very, very fast and on first raw out of the box, I like the sound More, yes better than dx220. To me it's got the same nice stage and detail/resolution (whatever you want to call it) as the dx220- that is everything is presented with plenty of space around each instrument and it has it's own place in the imaginary soundstage.
I was worried the soundstage wouldn't be as nice, but it is. Now out of the box the m11 sounds more exciting/dynamic and even a touch more open? than the 220 with stock amp. And I've tried to match the volume as close as possible too.
There is a softer cymbal type instrument in the background on Laika by Bluetech that starts around the 2:50 mark on that track. It seemed it was a bit clearer on the m11, as if the treble is just a bit stronger.
I was going to say I think the bass was more pronounced on 220, but the second track Fold and arrive, well the m11 bass is hitting hard and still sounds a bit more clearer livelier than dx220. To my ears they are very similar, and I prefer at this point the m11's more slightly energetic presentation.
I great stuff fiio, anybody wants a good price on a mint dx220 PM me.
Oh I used my akt8ieii out of balanced 2.5 for both. Wow, I keep switching to make sure my ears and mind aren't playing tricks on me and I just can't find hardly any difference. I'm listening to Joe Satriani and I hear the same floating around my head in 3d space as the dx220 on flying in a blue dream
Wow again! Excellent job fiio, will post more pictures.
