Respectfully disagree, JohnK. All receivers are not the same, and do not provide the same flat response across the frequency range. For example, I had a TOTL Sherwood receiver, terrible for music. It would be easy to offend a lot of folks who are fans of their brands, but, at least in my experience, the inexpensive receivers which do very very well with music as well as home theater include the Panasonic HE200, Yamaha, Onkyo, and some of the Sonys. (STRDB1070 and the ES line).

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
