i've had a DB940 for about 6 years now, bought it as my first experiment in 5.1, and it's been nothing but rock solid and reliable. movie performance has been great, music a little dry... but then again, my speakers aren't the most musical (not to mention i went from an ES cd player to a cd/dvd jukebox).
now i'm planning on going back to 2-channel, and i may just keep it as a pre-amp running to a 2-channel SS amp. i was originally going to ditch it for an integrated, but now i'm thinking i'll get more bang-for-buck keeping it.
