I have an 8080db that I liked very much before it broke. I hope to have it fixed soon. I have a 9090db that I did fix awhile back and like it very much too. Those are the only two Sansui units that I have listened to but I'm guessing that I'd like the sound of most of them. I'd like to go to an integrated or separates so what would be the next step up for a very noticeable sound improvement without breaking the bank. I have a TU-9900 that I picked up so I thought about an AU-9900 but those seem to bring a nice price most of the time so I don't wantt to buy one without making sure that it is quite a bit better. Would it be a noticeable improvement over the 9090db? I've read some good things about the AU-919. Do the BA, CA units sound better than the integrateds? I don't mind spending some money as long as the improvement is worth it. Any thoughts.
