Sold speakers you really enjoyed?... But why?

After several years of owning the Dynaudio C1 and C1 signature (honestly thought I would never sell or trade them) I did for the Raidho D1. I often thought what would it take for me to move on to something else. When I first heard the D1's I wasn't all that impressed. But they were brand new and being under driven for break in purposes. Then I found out the cost and said no way. Later that day I went and listened to the D3's. Wow!! Blacker background - better imaging and soundstage. Sound quality that rivaled electrostatics with better dynamics and without the size. That got me thinking more about the D1's but price was still a barrier. About 5 months later my dealer made me a killer offer including a 3 day in home demo. The in home demo was the deal breaker. They sounded so much better in my room with my electronics. Only took about an hour to decide the D1's were not leaving. Better clarity and more detail without being analytical or sterile sounding. The only part of the sound that wasn't as good was the bass. The D1's don't go as low as the C1's but for as low as they go it is a much tighter/clearer sounding bass. I would have to move up to the D2's to equal the bass of the C1's and D3's to better it. That said the D3's are way to big for my room. D2's maybe - someday
