I have being listening to 970 for around 3 weeks now and would agree with your review. This is my first pre/pro and in my opinion, the center channel and front stage is where I noticed the most difference.
The 970 opened the front stage to the point I can't believe some of friends thought I had a great HT sound system (prior to getting the 970).
