I agree with Abstract7 that with a "polite" speaker the Roland is likely to sound a bit warm and rounded. I tried the Roland 10 & 112, the Levinson 336, and a few other amps with my Dunlavy 4's. I found the Rolands to be "soft" sounding with a pleasant high end, but lacking in bass handling. The Lev had more slam and authority, but struck me as still a bit soft on the bass control. The mid and hi character was smooth and controlled.
Having said that, the build quality of both are excellent, and prices for stereo units are often roughly in the same ballpark for similar power (but this can be model-dependant, and monoblocks are a different matter altogether).
