This last weekend I picked up a pair of Boston Acoustics CR7's for a song and a dance (5 bucks). Later that same day at another sale (sunday afternoon price drop!) I picked up a NAD 3240PE AND a NAD 2100 for 10 bucks. The 3240 drives the CR7's nicely, really really good in fact. The question is, is there any reason to use the 2100 with these speakers?
