I've been to High End in Munich this week, and I think I tried out that Hifiman with those cups that remind me of the old Sony R10 for a short time. It does have a lot of bass, but those cups are much too large and its not as balanced as e.g. the D9200. I'd never buy any Hifiman model though, that constant churning out of new models gives me the feeling of wasting money for something that won't live long and doesn't have any support rather soon.
I did not try out much there, most models were simply not that interesting. I do like my bass, and I don't want to have to engage massive electronics since I want my setup to be as mobile as possible. Unfortunately Beyerdynamic did not exhibit this year, so I could not try out the T1/T5... but I tried the Liric, and although the Meze guys are really nice and we shared some drinks I won't get one: comfort is really good, sound is nice, but its a bit too power hungry and does not go deep enough for my taste (with the Apple Lightning dongle, mind you).
What surprised me was the DCA Stealth, which I'd exepcted to be rather bland after what most review said. It is not, and I'll actually give it another try. But it is much too power hungry for a mobile setup, so I probably won't get one either. This one I did try with some desktop amp though. Excellent comfort, and very lightweight. I love its folding concept.
I also checked out the DCA Aeon 2 Noire, which also has excellent comfort like the Stealth, but does not go deep enough for my taste (again with amplification provided by the exhibitor). I did not try that one with the Apple Dongle since I won't consider getting one.
Another one: that T+A offering, I even forgot its product name. Questionable comfort due to a much too small headband (it rests on the sides of my head, with an arch above where it does not touch my head at all...). Quite missing in the upper midrange and not worth the money.
The Raal Requisite: while an interesting driver, the overall construction is still very home-made. Plus its tonality was very off to me. There was another prototype with the same driver, and that one did sound quite good. Not mobile though, since the driver has a crazy low impedance and needs a transformer to work with normal amps. So no, I won't get one either.
Other things I ignored:
ifi GO Bar -- why should I pay that much for a simple dongle DAC?
HEDD -- just too heavy, plus its open...
any crazy electronics
Cables... there were even cable bridges or high rises... what should I say? Plus those totally crazy power cables with plugs that look like they are just made to destroy wall sockets.
Mojo 2 -- still charging via Micro USB, adding an EQ (which I'd never use). Too bad, I'd have considered a smaller Mojo with a less complicated interface concept, but adding another button with its own color scheme, plus keeping the dimensions identical otherwise, doesn't work for me.
and obviously tons of other things... I don't need to try another Focal e.g., and the Stellia does look as ugly in person as it does in pictures. That brown...
