I wanted to post some lines about the mg6pro's sound in relation to the Atrio, but I think you're too close to the forum servers and caused it to go haywire, wiping out the text a few times when I get whacked by a "Not Acceptable" error.

Being on the NOT so cutting edge I just got these on extended load for an audition.  There may be little more to say, from my first listen it appears @MuppetFace has pretty much nailed what I am hearing. 

The funny thing is that when I read the impressions in the past I didn't have them so I wasn't reading very closely.  My mind summarized things and I was expecting the bass to be huge.  Now that I've listened I realize that when folks said things like low-bass and deep-bass being emphasized they meant it, the low stuff, the real low bass... not mid-bass.

It's an odd presentation because everything else seems pretty well balanced, but when something digs deep it's all of sudden super emphasized!  Its like they wanted to create a fairly balanced sound but add a little sub feel/impact by kicking the hell out of the very deep stuff. 

So far, I'm enjoying them.  They are passing the weekend test to be worthy of spending the week commuting with me.  I'll put up my full impressions after spending some more time with them, but I don't expect to add much at this point.

On another, completely unrelated note I also got one of these Just Audio (built in the UK) portable DAC amps to try out.  Nice little unit.  I'll give it a spin too and report back in the portable section. 

Shpt and grhd:

Yes, tell us more when you've got some time.

fit was a problem for me. never could get a consistent seal. didn't have that issue with the ie80 - better ergonomic design IMO.
