Why hasnt yamamoto A-o11 gotten more love?

I've had an 08-s for a year and it's a fantastic amp. Just bought the 06-3 model which uses ad-1 output tubes.
Yes, one has to wait 3 months but with the right set of speakers
it's a marvel of an amp.
They make there own tube sockets, connectors and include tubes at the asking price!!!

The 6moons reviews have all been consistently positive.

Hi LA45
After about 8 weeks my Yamamoto YDA-01 DAC arrived today, well packed and in flawless condition. Right out of the FEDX box it really sounds very good! I may be in for quite a treat once it`s fully burned in. Flash impressions after only a few hours of listening, it`s very transparent, dynamic,fast and has a pure liquid-organic tonality. It only about 12 pounds but it has a big sound with authority and presence. It seems that MR.Ebaen of 6moons nailed it with his detailed review and subsequent comparisons to other high end CD players. I`m using a PS Audio PW transport, this is a good combination.

There is no doubt the s-phile sample was a fluke or damaged because quality control does not get to a level higher than Yamamoto's.
