I was thinking of adding a B&K 7270 (7 channel @ 200WPCx7) channel amp to my Pioneer VSX-49TX. I really havn't heard much discussion about B&K amps here, I know Rotel, Acrus, Parasound are well liked. Are the B&K's any good? Any comments or recommendations. Thanks. I have a change to get a new B&K 7270 from an authorized dealer for $2300...good price or not?
