You are wise not to jump to any conclusions. Alex answered my e-mail last week from Bulgaria (I am assuming). My Denon was also one of the machines he worked on when he was in the States last month. I got a very quick turn-around time, as well as a totally updated machine with new 32-bit DACs, wiring, digital input and Class A tubed(NOS) output stage.
I believe he is currently working on logistics for servicing his products while he is not in the States, as well as taking new production models from development into production.
I would send him another e-mail and/or leave a message on his phone. Hope this helps.
