For what is worth I own a pair of Emotiva differential monoblock amps [XPA-1L] powering a pair of B&W CM1 [84db] and they sound great in my room to my ears. I use an ARC LS28 preamp and the trio is superb. Emotiva is good bang for the buck. Here is a review [https://goo.gl/Gi8hF9]
in the review their most egregious complaint was the finish, but my amps were perfect.
