Ozzie, I regret selling my 840c. The unit does lean a little to the bright side. On most music it was fine but on certain music, mainly rock and blue's it could be a little fatiguing with my equipment. I should have kept it and used it as a transport for my hybrid DAC when listening to bright recordings. I miss the really pristine cymbals and resolution of the unit.
I'll probably buy a used 740c or 840c again in the future to compliment my system.
Over all I'm happy with my hybrid DAC which sounds good with all music.
