This is strictly my opinion. I have owned several Blu Ray Players in the last few years including the your Denon 3800 BDCI. The Pioneer BDP-09FD is one of the most well constructed Blu Ray players that I have ever owned. Its performance is arguably the best 2D picture and best sounding player period. However to get the best sound you MUST take advantage of the 7.1 analog output.
I have compared the Pioneer to Denon, Sony ES, Oppo-95, PS3 which are all excellent players. However, the Pioneer has always edged them out. The release of the latest Oppo-105 has finally changed my opinion. The picture of the Oppo -105 is marginally better then the Pioneer 09. Both 7.1 analog outputs on these players are outstanding.
I chose the Oppo 105 only because I felt it has finally surpassed the performance of the Pioneer.
The Pioneer's shortcomings is the lack of features, for example 3D that is now avaliable on most blu ray players and the loading time is slower then most newer players.
If you are looking for a player that delivers one of the best pictures and sound quality and is also built like a tank then the Pioneer is hard to beat.
I still have the Pioneer in my main system and honestly I do not have a problem keeping it there. However it does not make sense to keep both.
If you are interested I can sell it to you for $600 which includes shipping and Paypal fees.
I have all the accessories and the original box and it is absolutely in perfect condition.
