Denon 2012 & Marantz UD7006 are exactly the same players with a different casing.
I have a Sony 760 and Panasonic DMR BWT720 Blueray Hard drive recorder and they are both quiet and very reliable. The Sony was a bargain for £100. I also have 2 Pansonic DVD / Hard drive recorders which are also quiet and reliable. I also have a Denon DVD 1920 which plays all my DVDs perfectly and is bigger than both my Blueray players.
