Cool. That's good to know. I do have the RC1070 and really like it. I'll pass judgement when I actually spend some time on the DT770's. I'll also make sure to burn them in.

I tried on both the Ah! and 1070 output w/ my Super.fi's. I wasn't impressed. But I can't say if it's just the Superfi's or the amp output. I'll reserve judgement for now.
