Arcam A19 is a very neutral amp and is rated 5* on What-hifi. MA Rx6 series have definitely mellowed down compared to RS6. Am using this combo and find it very detailed and good.
going by reputation alone arcam is def a step ahead of the marantz. the ma's are neutral speakers and pair well with warm to neutral sounding amps. they dont pair too well with brighter sounding amps
