I haven't purchased yet.
Initially I thought I'd get the Crack amp to bring 'the best' out of my HD650s. But then thought a) I don't need more warmth, just the magic/life/holography/plankton/etc that comes with tube amplification, and b) if I could kill 2 birds with 1 stone and use Sex for headphones and a guitar speaker, that would be pretty awesome, and c) I just got AKG K712 and it would be nice to have the option to power them with this amp as well.
I'm still on the fence about Crack vs Sex. I started with HD650 and Magni, then moved to Vali 2 and like it a lot. The HD650 can still sound a little congested in the lower mids and I read that better amp matching can help.
