Replace Primare SP31.7 w/ Cary Cinema 11?

I have been considering a replacement for my Primare SP31.7 which is in a HT/2 ch. listening system. I have my eyes on a used Cary Cinema 11 (not the 11a), which can be had for a fair used price. But then, I start to consider if it is really worth it. I just got a Blu-Ray player and intend to simply use it's internal processing and analog outputs for the DTS-HD sound. Regular 5.1 sound will be handled by the processor, but the Primare does this quite nicely already, and I can use it's inputs for the hi-rez audio from the Blu-Ray player as well. The Primare also serves quite nicely as a 2-ch preamp, as it has an analog pass through.

The Primare is not the MK2 unit and is getting a little old, but this isn't necessarily the best reason to upgrade/change things, esp. if it does everything the Cary would be doing. At any rate, just wondering if anyone has thoughts on this or even experience with both units.
