No first hand information, but check out the posts in this thread:
Alex replaced the laser assembly in my 3910 on December 19. He received the player in the late morning, and he shipped the repaired player back to me the same day.
That's pretty good service.
For four weeks prior to that, he returned several emails promptly.
While he was in Dixon, CA, he completed orders and serviced players that had been waiting for him. His website has posts from several satisfied customers who received their machines after lengthy delays.
He returned to Bulgaria for Christmas, and he is still there as far as I know. He mentioned returning to the USA in early summer.
The contact info on the APL website is current.
That's as much as I know.
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.
