Just a side note now that I'm more awake...
I talked to Outlaw Ben about this as I was uncertain when I was purchasing...
You can Daisy Chain up to three triggered units from a source trigger. Beyond that you risk damaging the gear. So if you want Instant-On for most usage, trigger your front three, say, and set any others to Sense. There will be a slight lag as the signal goes through the system before the Amps power on. This has never bothered me.
Also, if you opt for triggers: you must use the 1/8" MONO plugs. Stereo does not work. Outlaw Ben was very specific about that.
I'm only linking this as a reference:
6ft 3.5mm (1/8 inch) TS Mono Male to Male Cable

You will notice it is a tip-sleeve plug, not a TSR (which would be used for stereo connections and have three distinct parts to the shaft rather than just two).
Cheers!
