Why hasnt yamamoto A-o11 gotten more love?

Does test equipment hear the same way we do? About the only benefit of test equipment is that it has no bias or opinion. Other than that its not human so it technically can't hear things from a human perspective.

Case in point: tube designs are generally accepted as noisier than transistors (and will measure as such), yet many prefer their coloration or distortion characteristics to be more pleasing than quieter transistor designed counter parts.

I agree, but a big channel imbalance is weird. It does make you question if something wasn't right with the unit, it seems to be pretty basic, and not too challenging to get right.

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.
