IMO, the 1068 is the better performer all round. I have a RMB 1075 right now but am using a Harman Kardon AVR 430 as my pre-pro, which images horribly and unstably, and simply is NOT anywhere in the same ballpark. It was cheap, and I'm a student, so whatever works!
I am after the 1068 asap, as it is more full-featured (which is great for me, as my setup is all-inclusive) but, I really don't think the differences in 2-ch performance really justify the higher cost. If you need video upconversion to component, and the latest firmware, that does justify the extra bit 'o brass, but I think you;d be fine with the 1066, as it is still a quality piece. I have auditioned both at my dealer, but only in HT setups and not 2ch. If your local dealer still has the 1066 laying around, see if you can convince him to give you a head-to-head comparo.
My two cents! Good luck.
