The Boston Acoustics A40 loudspeaker ($150/pair) has become "legendary" (ie, it's stayed around for a while), probably because a pair of them images as well as Rogers LS3/5As. Unfortunately, it is no match for the LS3/5A in terms of smooth midrange response. Of course, at $150/pair, it shouldn't be.
I was originally going to do a review comparing the Spectrum 108A ($200/pair) and the Boston Acoustics A40. On first listen, I was mightily impressed by the A40. But after Stereophile's Larry Archibald schlepped me out a pair of the 108As, I didn't much want to listen to the A40s.
