Otomon Labs. Soundgate Japan

I ordered from Ken-san 2 amps, 717A drive 45 tube amp and 2A3 Para SE tube amp, both of them are perfect and better than any amp that I had before. His work on wiring is awesome.  Here is my ordered amp -->> http://soundgate.net/product/NDkx.highend and http://soundgate.net/product/Njc5.highend

I dont know why you had problem with Ken-san but he is really kind and  professional. All my emails was responsed within 3 hours. I ordered and got the amp 3 months before but any when I send mail to him, he response immediately same the first day I contacted to him.

most of the recent issues seem to be related to the 1940’s Western wiring, which is very difficult to solder. but one can always opt for regular wiring.

allow me to add that the sound that KEN achieves is incredible. we recently did an A/B of this custom 71A amp...

...against an American custom amp twice its price, and KEN’s was drastically better in every way. it was also equal on low levels to a TAKATSUKI based 300b with all-TANGO iron, which is a prototype that will cost 7-8K when complete.

I just bought a 45/2A3 amp from Otomon Lab. This is the best amp I ever have. I don’t think I need another amp for my Lowther based horns. Ken Uesugi is a master builder of tube amps. This amp he built for me sounds much better than my previous Yamamoto A-08S (a 45 amp). It’s about the truth and spirit of music.

This is the amp I bought:

Ken is very cool. He just made a 45/2A3 convertible amp for me.
i have at least 50 years of experience with Hi-Fi and this is the sound 
I’ve been searching for. Only caveat: you must have speakers that are 96 to
97 dB efficiency. Otherwise, the amp just can’t give it’s all (and that can get plenty loud with lots of body). I will never part with this amp.
