So I don't know, I own an ODAC+O2 combo from Massdrop that's great with my K7xx's, and my Little Dot Mk II is brilliant with it, but I got these T70's a while ago for free off a friend. With the OCombo, it sounds tinny as anything, the mids are sooo far out there, but with the LD, everything just sounds hollow altogether. At least with the OCombo, cymbals from drums come out great but that's it. I listen to a mix of classical, some jazz, and rock. Any recommendation for an amp that can really really bring out the potential of the T70's? Edit: In case somebody thinks my friend gave it to me for free because it's defective, that's not the case. He bought a T1 and a Valhalla, so he saw no need his T70's anymore.
