Eldartford,
Can you tell a difference in sound between the MULTI inputs and the regular analog inputs? When I was doing my testing (several months ago) I thought that the MULTI inputs sounded better, so I run my turntable through the R/L of the MULTI inputs. According to Rotel, the signal path should be similar, but I thought that I could hear a difference.
Overall, I have been happy with my RSP-1066. For HT, I can't imagine spending any more (unless you really wanted lots of configuration options - crossovers per channel, more granular time delays, etc). As a combined 2 channel / HT pre-amp, it seems to fit my needs.
