Thanks for quick replies!

Right, so searching on 'Harmony' and my device [Cambridge Audio Azur 540r] I see someone on this site recommended a Logitech Harmony 525 in the past - which I've found on ebay too. Can I plug in 'hex codes'? I'm using the box, but cannot adjust speaker delays etc.

I know this is old gear, but this is my first start in surround sound - only used stereo hi-fi's to date.

Getting this going will set up my DIY cabinets/drivers.

Then I can save up for a nice *new* AV - in about a year I hope.

Anyway, will it work do you think?

Thanks everyone - it'll make my system 'harmonise'! (I guess).
