Hopefully no one's trying to draw the conclusion that on different system's, that the 1066 is quieter than the 950. I still have yet to hear of a direct comparison in the same exact system.

The 950 only exhibits its hiss with specific combinations of either speakers or amps.

Also remember that the very 1st rev of the 1066 also had a hiss problem. (Internal ground problem or something.) And, the 1066 has the double bass problem on the 5.1 analog inputs that you cannot get around (unless you use an ICBM with it).

BTW, rumors of a new RSP-1098 available sometime early next year...
