Arcam fan here too
I have the DiVA stuff, a CD192 with an A85 amp, hooked up to Monitor Audio RS6 speakers. I planned to add a power amp and tuner but have decided to save the pennies and put the upgrade off for a year or two, to see what new AV receivers they bring out. I'd love the AVR600 but it's a few bob over my budget!
Hope you enjoy it when it arrives, keep us posted with your findings
