I have a pair of DSP33s in my study (my second listening room) and had considered swapping these out for a pair of DSP3100s. The speakers are located in a crowded bookshelf and have little room to 'breathe'. That is unlikely to change.

Does anyone have any thoughts on whether this change would make a worthwhile upgrade, or any information in general on the difference between these two models?

One alternative would be to look at a pair of DSP3200s, though the non-cubic design wouldn't work as well in my bookcase.

Would this (3200) option represent a significant improvement in SQ over the 3100s (and 33s)?

I know this is all a matter of opinion, but any thoughts and experiences people may have would be very helpful.

Many thanks.

Neil
