patmos,
I wish I could give you an opinion on the 2 channel stuff, but honestly, I don't listen to that much music on my stereo. I only play CDs with the DVD player... The rest is just the radio.
I have been HUGELY pleased with the 950s performance tho'. My most major complaint is that I wish I could rename the inputs and I wish I could program the input buttons into my Marantz remote (i.e. the video 1, 2, DVD, etc direct buttons on the remote).
I've listened to the DD, DTS, from my DVD, the DD from my Xbox, the DPL-IIC from my Gamecube... All have been outstanding. Even the wife thinks it sounds cleaner and smoother than what I replaced...
Sorry I'm not of much help in your case.
...Jim
