Jim--if he's willing to go slightly above $200 (shipped) the Denon AH-D2000 is probably the can for him--provided he does not want a mobile can. They are made for in home use.
Here's a couple reviews:

The ways to get the best prices are to follow the above (post #16) link--EE is out of stock for now, but stay tuned, or to call J & R music and ask one of their sales reps for the Head-Fi special on these cans or best price.
If mobility is important to him, the good but not as good Audio-Technica ATH-M50 or M50S (with a straight cord) or Shure SRH 840 are good choices. The AT is more of a basshead can and the Shure is more neutral with a slight mid base hump.
See for the AT:

Whatever you/he do/does stay away from "lifestyle" cans like the Beats & Skullcandy. Almost all of them or crap or mediocre at best and virtually all are grossly overpriced.
