You can use 32 amp breakers but there are two drawbacks I can see:
1.) They may not protect your equipment (trip quickly enough) in case of an internal component failure or partial short.
2.) You will have to use very heavy (and expensive) wire in the wall to comply with code requirements for 32A circuits, and then how do you connect 8AWG conductors to standard, even 20A, receptacle hardware?
If you are that worried about your amps tripping breakers, I think it would be more cost effective in the long run to give them each their own 20A circuit. By the way, even with 20A circuits, if you're 80 feet from the panel, there is going to be voltage drop. I suggest you go up one conductor size in the wall (like 8AWG instead of 10AWG) and then reduce it back down to 10 or 12 AWG in a make-up box near the outlets so it can be connected to the receptacles. (Remember, it's only a 20A circuit, so you ARE allowed to reduce the wire size down to code size before the receptacle.)
