FWIW, if you're also considering home use set-ups, the tube headphone amp I chose for my AKG K702s is the crazy good Raptor by Ray Samuels Audio. Most important to me was to satisfy these two questions, which would apply to any purchase, portable or home, tube or SS:
1. How real and alive does the music sound with this combo?
2. How long can I listen without fatigue?
IMO, the answers are: Unbelievably, and Longer than I can stay awake! I've had these ear-speakers on for 4-5 hours without any fatigue, loving every minute.
Both units are worth the break-in time.
