I prefer Sansui, I have a au-999, a G-9000, a G-9700, an au-517, a 9000z and a QRX 9001
had but sold a g-8000, 8-4700, Z9000 and a 9090
The only one I didnt care much for was the 9090, maybe it was the one I had but it sounded a bit darker and less detailed to me.
I picked up a Pioneer sx1250 and very excitedely had it completly restored, the deluxe restore, everything including the big caps!
Hated it, thought it was gonna be my main system but got rid of it quickly, it didnt have the high end detail the Sansuis have, the guy who restored it liked it, said it had a lot of Bass so I traded it to him. I suppose if you like the 9090 you would like the pioneer, kinda similar,
just my 2 Cents...someone else will suredely think exactly the opposite!

I have a guy at work whos dad has a 780, very unreliable apparently...I have had it fixed for him twice, and from what I hear its nothing special.
