The stratus series IME is hard to drive in general and has to be pushed a bit to open up. I was able to drive a pair of stratus silvers with a 60W rotel amp. This was a seperate amp that weighed 20+lbs though. The silvers didn't really shine until I got a Bryston 3b-st.
Amps are a good buy used. If you can use the Cambrdige as a pre I would pick up a 100W rotel amp from as few years ago and try it out. You can add a real pre later if you want. If that doesn't help then the Mini's aren't for you and just move on.
