170 watts of something to behold. The AU-20000 was the biggest integrated amp that Sansui ever made, and is a true work of art from a sonic and industrial design perspective. From a collector's perspective, this is one of Sansui's three kings. From our perspective, the AU20K is the most stunning Sansui piece all around. The cabinet on this piece has a couple of scuff marks, but you won't notice them at a listening distance. It's been fully serviced, and sounds gorgeous. Peak Sansui.
