Advice from Audiogon family - best speaker $3k-$4k

These are exceptionally good. The BMR Tower. You won’t do better!  They are tremendous value.

If you liked the Sonus Faber, buy them that's my advice. Otherwise go listen to a bunch of others in that price range and if you like something you hear better buy that instead. 

If you have the room to set them up properly, Magnepan 1.7i.

A great alternative to Sonus Faber would be Vienna Acoustics. 

If you like B&W (as I do), try to listen to the ATC models in your price range. BTW, I think B&Ws so good, it's hard to imagine anything price-comparable which is "superior on every level". Bass could be better, but subs easily help this.
