If you are finding your Arcam amps a bit short of grunt and punch try setting your input trim to max. Tried this a few years ago with my old dynaudio speakers and it did help a bit, but not huge differences but the dynaudio's are quite insensitive.
Tried this again recently and this significantly improved the dynamics and punch from my monitor audio rx6's. :dance:
