Check out the Power-One CP131A.  It's got 5VDC @ 8A and +/-15VDC @  
3A.  Should be beefy enough for an expanding system.  You might use  
the CGS PSU Delay Boards if you go with one this size, to prevent  
latch-up.  Another option is getting something like the Power-One  
HCC15-3-A for your +/-15VDC and a separate 5VDC supply.

You could use the Neutrik 4-pin Speakons, wiring +15V, -15V, ground,  
and +5V on the 4 pins, but it's probably good to keep your analog and  
digital grounds separate for noise's sake, so the 8-pin Speakon might  
be better.  Those guys can handle 30A continuous per contact, so they  
are definitely strong enough, whereas the DIN connectors are better  
for smaller distribution schemes.  With speakons, you can just use a  
Speakon cable between different cabinets.

You might get some distribution ideas here:

On an unrelated note, I really dug your performance with Melvins @  
Symphony Space last year.  Lysol w/Haino was intense, though Haino  
was almost too much - wish he knew those changes!
