Long time since I have posted here! I concur with the above comments. I upgraded from the Opus 21 / s30 system to the Cantata system and could not be happier. The amp has a bit more breathing room and openness than the s30, but still retains the musicality of the DNM-based design. I use them with DNM cables and Harbeth P3ESR speakers. A great little (and beautiful) system.
