Hey guys, I realize that I've done made a similar thread to this but this time, I've narrowed my amp/DAC choices to only two. Should I get the Audioengine D1 or the O2 amp with the Schiit Modi? I would prefer an amp that can scale to something higher, such as the Sennheiser HD 600's and can still sound good with it. My preference of the sound signature is mainly to just increase the detail, musicality and such of my HD 598's, though I'd love it if there was farther bass extension and slight emphasis on the bass to give it a little punch.
However, it really doesn't matter as long as it sounds good with the headphones and can scale over time so if I upgrade my headphones, I won't be in a hurry. Anyone who has tried either of these amp/DACs (including the Schiit combo or the JDS O2 combo) or who has compared them that could give me some comparisons between the two would be most appreciative.
I am not in particular looking for other options, but if there is another great option, I'd be glad to hear it! (no tube amps or FiiOs though, please! I'd rather not keep buying new tubes and I have tried the FiiO E17, I thought it was pretty good for the price but it's not what I'm looking for.)
Thank you in the future, for all your help!
