Denon 3910 Universal Player - Opinions?

I borrowed a Denon 3910 from a local retailer for a few days. Hooked it up to my Krell Class A system. It was a letdown in the audio department. Granted, the picture quality was first class. However, the sound quality was boomy in the bass, muddy in the midrange and rolled off in the treble. CD and SACD were similar results. Recommended highly for cinema. But if you're looking for high end audio, you won't find it here.
