Obviously, critical listening between the three is the way to go. But, for my money, I would get the RSP-1068. I own an RSP-1066, and when I do upgrade, it will either be to a 1068 (as an intermediate step), or more likely to a "final stop" pre/pro, like the Krell HTS 7.1 or EAD Theatermaster 8800 Pro. Of course, if Theta Digital ever comes out with a redesigned Casanova, that would probably make my short list, too.
I'm sure that you've read all the positive reviews of the RSP-1068. It tends to get compared to units costing two or more times its price, and so far, it has fared very well against even these more expensive units.
Please note, though, that I have not heard the Cary or Meridian products. They are not readily available for audition in my neck of the woods. I am sure that they are worthy contenders, though.
Good luck, Tom.
