Just picked up a 2200 for my system and although it is not "burned in" the difference (read improvement) in the sonics so far is really nice.
It makes me wish I had more listening time to go through some of my old CDs they sound so good.
The improved resolving power over my other CD players (Rotel, Luxman, Harman Kardon) is quite distinct and noticable.
While it is still a bit agressive, I have to admit to having the volume turned up much more now than in the past without the former "edginess".
It is certainly a miner, when it comes to detail. It reaches down and pulls up resolution and instrumental attack and timber I had not heard before.
If the 2900 does a better job than this I tip my hat to those who own them.
As far as the Pioneer, I have not heard it, but depending on your system and its ability to sonically decipher detail, this player "out of the box" is a winner.
I too was not interested particularly in video perfromance, but for the record, I watched a film last night, and I won't say it made my older Rear Projection SD TV turn into HDTV, but I will say that the video "was" much improved.
And aside from just viewing the film and seeing deeper blacks, crisper detail, and beautiful color without any bleeding, I had one other clear cut sign.....
The credits. Yep when the credits roll, They were pristine, compared to the older player (a top of the line Cinema Series Toshiba 9200).
Oh Yeah it was impressive.
And one other thing. The HT sound through a Harman Kardon AVR7200 was excellent. I didn't listen critically, but just to enjoy the movie, but it sounded as good or better than ever. And I did notice very clear dialogue (but that could have been a sound engineers good work)
Sorry I can't be of more help regarding the Pioneer.
