I just picked up a pair this morning. My jaw is on the floor. 846's are gonna stay in my ears all day!
I'm listening straight from my macbook but already these are leagues ahead my IE8's/ibassD10/iMod rig
I picked em up brand new from a local dealer for less than 999.99, tax included and everything. If you find a store that sells them locally you might be able to haggle. Or find some 2nd-hand on head-fi
The JH3A's were supposed to have active crossovers and not passive. But Jerry ran into some patent problems. No one has heard the new UM rig so no one knows yet. Everyone will have to sit tight for first impressions.
The smoked shell is always a good choice, especially with a brushed metal/aluminum face plate. But it's up to your personal tastes really. I think the inlay's are really ugly. If the two different materials were blended together in a design that was more aesthetically pleasing than just stripes.
