Best vintage Sansui integrated


Would like some feedback from those who have owned them. I am thinking of buying an Sansui AU-717 or 919 but wondered if people thought any of the later models like the AU-D11 (see below from the 'best of sansui' site)

"In 1980, the third generation of the 07 Series AU-D607F, AU-D707F, and AU-D907F were introduced in Japan. The international version equivalent to AU-D907F was AU-D11. Specification-wise, AU-D9 was more likely AU-D707F. The sound of those amplifiers was notably different from the previous Sansui amplifiers. Instead of very strong high frequency in the professional to AU-919 series, this generation of the 07 Series had very soft and natural high with the powerful low."

I had the 919; I think the consensus was that it was better than later ones. The high frequencies were fine on the 919. The AU-X1 was even better but hard to find; I had one of those also. I had these at the same time I was a Krell dealer so had good amps to compare them with.
My roommate had the AU-717 when it was a current model and I still think it was an incredible sounding amp. It was 85WPC. Not quite enough for the low impedance load of Double Advents in parallel though as sometimes it would shut down during extended high volume sessions with Michael Jackson or Greg Kihn playing. It always turned back on after a little rest and cool down and still sounded great.
For all ordinary uses the AU-717 is a great amp. Is it the absolutre best ever..., no I have better amps from other manufacturers.
