Today i was able to try out a Roll Music System rms755.
I compared the compressor with my other vca's - foote 3ps, tk-audio bc2-me, dramastic obsidian, bettermaker c502v, wes-audio dione, elysia x-pressor.
The RMS755 makes a fantastic figure. Very lively, large, enormously good stereo image, nice glue, very musical control behavior and good adjustability, excellent technical values - it simply sounds much more expensive than it is.
I am amazed that this device is not better known!
