Guru I haven't heard the 3910 yet so I really can't make an informed comment.
On the 2900 the areas I heard "better" than the "50 were in the soundstage and throughout the midrange, where the 2900 was more lifelike, especially in it's presentation of vocals and flute. (I hear a lot of both live at home from a professional musician)If there is a weakness it's in the detail area. I'm still not convinced that detail isn't overdone as an area where real music lies though. I'll take correct pace and tonality any day.
My listening room at home is where I A/B'd them and it was a borrowed "50 I used. The room is quite neutral and well set up as a dedicated listening room. I have a small computer desk in one back corner but it's shut down during listening sessions and each wall plug is a dedicated 20 amp line. (4 of them).
