Otomon Labs. Soundgate Japan

Has anybody purchased an amp made by Ken Uesugi from Otomon Labs/Soundgate in Japan?
I’m seriously thinking of getting a 2A3 amp, but keen for any feedback. Everything I’ve read looks good, but buyer experience is invaluable. 
Thanks in advance. 

I'm surprised that I won the auction because there were a lot of bidders and the action was hot until the end! 
Ken's site on the BAY has a lot of nice audio gear at reasonable prices! I also bought two Fidelity Research tone arms (FR29, FR54) from him. Prompt and safe shipping!
Thanks so much for this feedback.
I've committed to a 2A3 and now at the stage of deciding on one of his parallel SE builds v's the standard 3.5w SE designs - more or less same price. I'm also going with a copper chassis. It will be a 12 week build time!

Until now, Ken has been the best kept secret in audio. When I say audio, I mean vintage and bespoke Japanese audio MANIA. The man is a master of this mysterious art, a mad genius confined to his dark, smoke-filled workshop. Take a look at the selection of items he lists on his website. Some seem like junk, but are in fact carefully selected, exquisite national treasure goods. He can make a fully bespoke amplifier using any of the legendary parts to your exact specification and budget. I personally have experience with two type 71A amplifiers, the latter of which was custom designed. I asked for a somewhat dark sounding piece with lots of drama and emotion, which was delivered in spades. I asked for a specific design using natural wood and raised copper plates, and he allowed me to participate in the design process on the level of layout. You can see the finished piece in a recent post to the website. Finally, it was surprisingly affordable. I was so happy with the result that I ordered a matching phono preamp, which is currently in the works. Overall, an extremely unique and satisfying experience, a throwback to the golden age of mania.

Hello sir, how are you?
Please, can you tell me more about the Otomon from Japan?
I’m not finding too much info, just found your experience and another user that described a disaster situation..
Do you know more people that purchased amps from Otomon?
Any additional info is very much appreciated! I do not received his e-mail back yet...
by the way, I think I not fully undertstood about the amplfiiers, appears to be only vintage pieces, including lots of vintage components inside that shows a lot signs of use...
He build also new ampliifiers, with new components?
Honestly, I do not found the build quality impressive, I’m missing something?
Please, let me know, many thanks! best regards!
