I had the loan of a Streamliner 600 for a while and compared it with my Orange Terror (using a US P bass and Tech Soundsystems 4x12). The Streamliner was pretty nice, and a little more flexible tonally, but lacked the punch of the Terror and was nowhere near as loud. For me and the type of music I was playing at the time (heavy "dark" rock - Paradise Lost, Katatonia type stuff) it wasn't the right match, IMO. I could see it working really well in a less aggressive band though, and would probably be a better match for what I'm doing now (straight ahead pop/rock covers) and, although I'm VERY happy with my current Ashdown LB rig, I'm curious about a Streamliner 900 with a pair of nice 1x12 or 2x10 cabs...
