Thanks spinaltap. It was your very thorough review of the DSP3100s last year that got me thinking that they might not be quite right for my listening space. I will make an effort to listen to them and the 5200s back to back at some point soon.
I suppose I had been hoping that the 3100/1600 combo would lighten the bass load on the 3100s to the point where midrange control wouldn't be an issue. Its a big cash jump from 3100/1600 to the 5200, but apparently worth it. Will try to give them both a listen.
thanks for your input
