Excellent question. I was wondering the same thing. I went to Lyric Hifi and did A/B comparisons. As much as I wanted a SS, the 2275 sounded way better. There are two main drawbacks though. The 2275 didn't handle as well lots of complicated passages with many instruments - it has higher distorsion than the 6900 - in addition, the 2275 has a 75 Watt max. It all boils down to what do you want it for. With not very sensitive speakers, try the 6900 - but be aware the warmth is gone. Opera? I would go with separates. Jazz, soft rock...? You can't beat the 2275. It's the best integrated amp I have ever listened to.
