Some notes in the process of finding properly sealed cans for the office:
I just spent some time listening to the Senn Momentum, very balanced overall, but too bass-rich for my taste (on all amps) Fortunately thanks to the great EQ in the AK100, I was able to tame it just enough (I REALLY wish they'd let you save presets)
Sidenote: Since I had them handy, I threw on my W-3000ANV (EQ off, no bass reduction) and listened to the same set. Despite opening up the soundstage, the whole thing sounded a bit thin at any level (not maxed out), compared to what I'm used to. Put them on one of my favourite amps, the Peachtree, and the magic was back (still same set) So definitely, with some headphones, the AK100 sounds comparatively thin. And this was a clear difference, I'm not the most picky of Head-Fiers. Not night and day, not unlistenable, but nonetheless noticeable.
This turns out to be in line with my earlier impressions with the TH900, which I like a lot with the AK100: the same effect that is detrimental to the SQ of the W-3000 is just enough to tame the SQ excesses of the TH900 to make it more enjoyable...
Back to closed cans: So far I have tried the Momentum and the PSB M4U2 (usually assigned to other duties), and it's not as clear as I'd like it to be. The Senn is great but with too much bass, the PSB doesn't have that issue but sounds a bit meh, and in passive mode maxes out the AK100 (active mode is way too colored for "audiophile" listening, and of course adding noise-cancelling introduces the typical NC hiss on top of that)
Anybody here who can comment on the B&W P5 or Edition8, preferably on the AK100? Other suggestions? IEMs not so much, I need to take the phones on & off quite often at work...
