If you're prepared to pay those prices, those look like pretty good ratios.
The 770s have more bass than the DT880s but I would have to say, to me, the 880s are a cut above the 770s, some people like them though.
If you're going all out on a head-fi system then I would look in to the HD600s. They're great, and work with just about anything. I wouldn't trade them for anything in the same price bracket. My DT880s went bye-bye when I got them. But again, some people prefer the DT880s to the HD600.
There's also the option of buying a set up with the DT880s just now then buying a bassier pair later on, or vice-versa.
The Ultrasone Pro series are about the best for bass around this price-point.
You may also want to have a look on eBay/Head-fi for used pairs of headphones already burned in at a much cheaper price.

Depends on his budget. Sounds like he may be able to go the DAC and independent Amp route. Depends on headphone choice too.
