I have both the Streamliner 900 and Shuttle 9.0. They sound very similar to me with the STM-900 being smoother and the STL-9.0 a bit more modern and hi-fi. I favor the STL-9.0 when I want a more guitar-like sound. After getting the STM-900 I used it almost exclusively, now I find myself using the STL-9.0 more.
Just my opinion of course, and both are really great amps. You can't go wrong with either.
