I just ordered a pair of Beyerdynamics DT-770 Pro 250 Ohms headphones, and now I need an amp to run them. I prefer neutral sound, and prefer ultra clarity for stringed instruments (guitars, violins, cello, ect.) and mids and bass that aren't muddied either. My budget is $200. I would prefer a bass boost, because occasionally I do enjoy some rap/electronic music that would benefit from it, but don't want to have to deal with the extra bass the rest of the time.
So far, I am comparing these amps:
JDS Labs C5
Leckerton Audio UHA-4 AD8610
Electric Avenues PA2V2
I need enough power to drive 250 ohms, and would prefer more power to move up to a 600 ohms design later on. I would also like them to be able to drive sensitive IEM's, such as the Etymotic HF-5's.
