I've had the 970 for about 4 months now and find it a vast improvement over the Denon I had. More I have had no problems with compatibility issues (as with the Denon). The picture quality blows away the Denon by far - no digital blocking problems, no combing. It up converts beautifully on my 60in Sony SXRD with spectacular results. I also find the sound an improvement over the Denon - lighter, more open.
I had the Denon as part of my reference system for evaluating DVDs on my site (that’s a lot of viewing) and dropped them due to several issues. The OPPO simply is incredible and if I had paid full price for the Denon (retailing for $1200.) I would be swinging from rope after writing this.
I don't think you will disapointed.
