I think it's probably not been reviewed in any English language magazine so hasn't had the wide exposure that the A-08/A-08S received. I have had mine for coming on two years now and it never fails to please. I have a number of other amplifiers that I switch in and out of my system but I always end up hankering to put the A-011 back in the rack.
With regard to the Stereophile measurements, JA does mention that the bottom cover on the review sample was somehow missing and therefore it was possible something had become mis-adjusted.
