Thank you, that was what I was planning to do as a first step. And, yes, the DSP6000s are what I'm looking for, if only because they look amazing!

One question though ...

I've got two sources, before I add a Bluray player and projector. Roon/MS200 and a Chromecast dongle for podcasts and iPlayer Radio.

I understand that I need an AC12 to connect the MS200 to the speakers but where does the 568 come in the chain? Does the Chromecast and MS200/AC12 go into the 568 or does the MS200/AC12 still go straight to the speakers?

568.2mm, HD621, DSP6000s, DSP5000C, MS600, Roon
