Totally NOT in agreement with Pubul57.
No contest with the Yamaha 2000 series.
Circuit topology, parts quality, assembly quality and surface conductvity of signal route is nearly on-par with Accuphase.
The AS2000 cannot be compared with an AX-596. The 596 is a good amp for the money. The AS2000 is in another league altogether.
Unfortunately, the AS2000 has been removed from Yamaha's 2012 catalogue. The snobby nature of our hobby makes it hard to support this product when one can purchase a Simaudio Moon amp for less money. And that's a shame. This Yammy betters most of the competition at this price level on sound, (including the Sim) smokes them on features, and is STILL built to last 30 years - something that cannot be said of many flimsy boutique amps out there.
No that there aren't any left at dealers - I think it will become a classic in due time.
