hi dda,
This player is the same as the DP-450.
A so called DP-450 cloned (Same hardware, just different name)
All you read on the DP-450, counts for this player too...
H&B develops their own firmware i think though but i'm not sure...
About how these players work, i dunno...
Never tested (we only accept networked players) but surely there are many sites with reviews and discussions about this player around.
