to add to Brians post (if you don't mind)

everything depends on the other equipment found in the system, obviously not just the prepro. My ATI 1502 and Monitor Audio Silver 5's are highly accurate while providing lots of detail and air. Therefore for me, i believe the Rotel would be the best match for my set-up. With the 950, i find the sound to still be accurate but on the edgy side of things. I'm not implying that the addition of the 950 makes my system harsh by any means, just a little on the edgy side. This only applies to music, dd/dts sound is right on in my book.

If only the 1066 had 24/192 DAC's the decision would be much more simple for me...
