My HD 650s have practically been sitting in a corner for years because I keep getting dissuaded from the amount of amp choices out there. It's actually gone so far that I ordered a pair of inferior HD 598, as I assumed the impedence would allow me to run it just fine with no amp.
A few posts I just read have implied that that isn't the case, and even low-impedence phones need amping. Thus, I have no choice but to finally get the whole amp thing done and over with (or start, as there will be the inevitable trying of different models).
The main problem I have now is, simply, figuring out what will drive my headphones to their full potential. I feel that I can read this forum all day, but there is too much of the subjective mixed in---I just want to know what is going to provide ample power to my gear, rather than what kind of sonic signature is going to be imparted.
What's really confusing me is how some say even portable amps like the uDAC can drive something like the HD 650 well...but really?...
