With heavy Mylar use, precision tone controls with fixed indents, separation features (with a active crossover in mind as well) Full PNP Pre-Amp with a DC priority Power Amp and to top it off, it's one of the most aesthetically pleasing units we've ever come across.

So it's no secret that we at HHA love us some vintage Sansui electronics; they just check all the boxes in terms of price, performance and overall classic vibe. The AU-999 & AU-9500 (of which we've had many) are the two most coveted Sansui integrateds and for all the right reasons. They're performance champs on every level. This AU-999 is currently setup with a pair of Yamaha, NS-1000 and the combo is killer. Can't imagine how many Sansui components were paired with Yamaha & JBL monitors back in their time. Special synergy... So this AU-999 is in terrific condition considering it's age. Been through front to back by our expert in house tech and is now performing to spec. Don't miss this one - just a real slice of classic Sansui muscle.
