Mine's here! Battery was stone dead - power switch was in one of the on positions, so no listening impressions for a while (and I am at work....). Arrived double boxed in a plain white box, which I immediately put a gouge in the top of, using a metal ruler to cut the outer box tape.
So far:
1) Not quite as much a beast in size as I thought (feared), but none the less, (much) bigger than the average portable, though from what I can see, smaller than CLAS + ALO MKIII. About 1/8" longer than my iPhone 4S in the biggest Mophie Juice pack and maybe 1/2" to 5/8" wider. Definitely
2) Charger is a beast, Dell laptop charger would likely work if the charger pin was smaller. The Dell Charger is 19V, 4.6 A or so. Mr. Goodman, care to confirm if this would work, of a tip adapter or new tip were installed?
3) Dude.... NICE Rubber Bands!
OK, 3 minutes listening to DSOTM. sounds great, filters are pretty subtle but noticeable. On the HD650's, the impedance switch sounds the same in the first two positions, adds some noticeable bass weight on the 3rd postion. I haven't decided yet if it also adds flab or not. Low gain is plenty loud enough with the HD650's, medium is fine also. High gain will not be useful to me with the HD650 or Mad Dogs. Might be if I ever try to drive the HE6 or something, just to see what happens.
