I have an Integra DTC 9.4 and the Sony compares very well in sound quality ... maybe even better than the Integra. I've spent some time with the Sunfire and it's OK, but I don't think it's as good as the Sony. Heard good things about the B&K, don't have personal experience with the rest.

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