Out of curiosity what IEMs did you use? The channel imbalance isn't a problem for me, but I do tend to listen to stuff at moderate to loud volumes. With the Leckerton to UERM the stop on the pot is at about 7, and I listen around 10. The imbalance goes away around 8 on mine. I know QH said it's already too loud past the imbalance for him as well, but a few people are having Leckerton lower the gain to make it more usable.

I realize the design of the pot isn't great for portable use, but you bumped it when it was on a desk or sitting next to you? Maybe time for some coordination exercises 

Obviously, I don't have any problems putting this in pocket. And yes, I can still turn the volume knob within a reasonable range, in pocket.
No imbalance problems with my mg6pro and B2 either, but my ears aren't that sensitive. Some guy on the head-fi thread had his gain lowered to -18db so that's always an option.

I've never had ANY issue with the volume pot on my UHA-6S MK1 being accidentally bumped. Ever. Mine seems really stiff, and when I bump my hand against it it doesn't budge. If the MK2 is stiffer it wouldn't be a problem for me at all. On the other hand, I find the Glacier's dial irritating to use. It's surrounded by paint too, so I'd worry that the nomenclature (Craig on the brain --- lol) would rub off eventually since my fingers are sliding around all over the fascia. On the Glacier I received, the dial would slip back deeper into the case when a moderate amount of force was exerted on it, so it was also really awkward to try to use. I pointed this out to TTVJ, so hopefully the replacement they send will not have this issue.

How much easier is the MK2 to scratch over the MK1? Again, I've never had an issue with my MK1 (in black). I usually keep it away from keys and stuff when I'm traveling however.

The Glacier I had was also picking up all sorts of noise from other electronics anytime it was close to it, whereas the Leckerton is as silent as a boneyard. It's supposed to be shielded, but maybe because it's so slim there's less protection? Iunno. I just hope this was just a fluke with the unit I had.

I get a channel imbalance with the Leckerton MK1 when the volume pot is turned down all the way to very low, but when it comes into listening range I get no imbalance at all.

Note to kunlun: tone it down a bit, dude. I get that your online persona is brusque and we're pirates and all that, but I see nothing wrong with shane's post. Also not everyone here has to agree with reviews from purrin or anyone else.

UERM best with ______________.
