I've tried both players.
The 840C had better synergy with my system at the time. The mids and highs are a little more forward and the digital inputs are a big plus.
Now that I've changed speakers, I've moved back to Marantz, the SA-15S2. Which is warmer, has a bigger soundstage, and also has a fuller bottom end.
As far as I know, only Marantz's upper players are available in a silver/golden tinted face.
