That's a double-edged sword really. One the one hand Mikhail has almost certainly put in some time designing the amp and maybe building a prototype (who knows, I'm trying to see the glass half full on that one) but on the other hand you've been way more than patient and he's missed deadlines for what, over 6 months or so know? I could easily justify going either way with it if I were you, crappy position to be put in for sure. Good thing is that next weekend you'll get to hear the K1ks out of the beta since I'll have the adapter for you then and I'll also bring my iron so we can just wire up the 4-pin jack.
