So I finally got to give the Red Fighter a run out last night.
It has two 500w analogue amps in it, only one of which I was using last night, and it just sounds huge. I haven't had much chance to play with the gain structure or OK yet, but it felt more solid state than the R-400 - I imagine this will change if I cranked the input or hit the crunch switch. It slammed through my 2x12 - if I had two 4ohm cabs I'd be able to run both sides of the amp, which would be ridiculous.
It's a big beast, but it's not actually that heavy. I imagine it would be a pretty easy lift once it's racked up.
And the construction quality is, as I've mentioned before, MESA standard. No cheap plastic or parts. Just solid quality.
Oh, and did I mention the pretty lights?
