Hi, I know there are other posts relating to the oppo 105, but I was hoping that someone may be able to give comparison with the Denon 3800BD.i am thinking of purchasing a new Blu-ray to obtain a more upto date machine, however, the main use is blu-ray & DVD playback via the in built DAC of the player as my arcam av9 (which I have never considered changing due to its superb sound) is unable to decode HD audio. The main reason to update is to see if the picture & sound (latter being the main reason) can be improved. Considering that my Denon was a high end player, I am dubious whether the purchase would simply be a side ways step for audio / video playback,but obviously upgrade for other features that I may not use often, if at all.any advice greatly received.
