Superb machine. New sound for Sansui, more delicate and cleaner than previous generation (AU 717/719) it has been a breathtaking surprise for the affordable price vs the excellent performance. Also the building quality is much more than decent. Buy it with great confidence.

Well I have two AU-D9s and when aligned properly they are some of the cleanest sound you'll ever hear. I biamp with them one amp per side to drive the bass w/ up to 95 watts and up to 95 more for the mids and highs. Oh, I drive Yamaha NS-1000Ms



Locations of fuses

Does anyone know the location of fuses in the AU D9?


re: Locations of fuses

I'm pretty sure they are just behind the front panel (right side as you look at Amp) Hard to get to! I hope I never have to replace mine! Have you checked the Zero bias adjustment and DC offset? With the feedback of these amps if the DC isn't within tolerance the relay will not turn on the unit. See manual.
