I have seen the Denon in action, but not the Pioneer.
But from what i can tell from forums.......the Denon is an excellent player for blu ray and DVD. I heard it play cd's through a Denon 2310 receiver and Q Acoustics 1030i, and was quite impressed. (Again the quality of cd reproduction will depend on the receiver, as mentioned above).
The drawbacks for the Denon are firstly the size of machine (if that bothers you), and secondly, it is meant to be very slow at loading up.
The Pioneer, I reckon, will be similar in quality, but with slightly quicker loading times. It also has Profile 2.0......again if that is something your interested in......
So, to me, it comes down to the price and whether your happy to wait a little longer for loading times......personally, I would buy the Denon for that price over spending £500+ for the Pioneer, but I always like a bargain!!!!
Thanks Pete Ive done it now because I like a bargain too,Hope it works out that way
will keep you posted when I get it
PS am I right in saying Profile 2 is thebritish profile?
If so Why would the Denon be only profile 1?
