Before you rush in with a new speaker choice, I'd suggest that you really try and understand what's going on in your listening room. Small speakers are not normally known for "too rounded in the bass". So this implies to me that the position of the speakers (against the wall) has greatly boosted the bass you hear. If that is so, then any of the bigger Harbeths - which have more bass than the mini-monitors - will give you a bass that's even more boosted.

What speakers did you use before the Stirlings and how did they sound in the bass?
