None

I now have three Pis with HiFiBerry Amp+'s all running Moode for multi room audio. To tidy the installation up, i'm putting them into a wall mounted box. I'd like to keep it simple, so was thinking about replacing the 3 power bricks with one!

Am i right in thinking as i have 3x50W=150W, i'd need:
12v >=12.5A (150/12) powersupply
...
18v >=8.4A powersupply
?

and if so any suggestions? ...or is this a bad idea for any reason?

Most likely you won't need 3 times the power expect you will run exactly the same music on all 3 Amps. As the load can be very dynamic, some power supplies have trouble to manage this. Look for a good-quality (not the cheapest) 12V/10A power supply. This should do the job. However, we never tested specific power supplies for this, therefore it's on your own to check what will work fine.

Best regards
