Hi Folks What are your opinions on this power amp and matching it with an Arcam Alpha 9 integrated amp? I've already got an Arcam 9 & 9P set up but looking at buying another Arcam 9 integrated and matching it with the 290. Will it sound much different to the Arcam 9P power amp? These will be going with another set of B&W 602 S2 speakers. Thanks
