Given the low crossover of 200hz, I'd say the upper freqs are under powered, especially for someone who like to crank 'em until just short of farting....however loud THAT is!
The 50:50 power point is around 350hz for 'average' music. Right now, I'd suggest your REF500s are running into the wall sooner than the 1000s.
It's not that the ribbons are more sensitive and not needing 'much' power, but that the music above the crossover contains less and less energy, meaning you don't need mondo amps to run it, just electrical compatibility.
Another ICE amp would work for tri-amping....just keep the power to frequency spread within reason for the crossover. IOW, if you cross to the ribbon at 10khz, you may only need the 125 watt module. At that point, the 500 for the mids would drop back into line.
If I had your level of bad habit, I'd think seriously about with Pass amps. If you insist on sticking with the bi-amp setup, a selection of 'a' amps would work fine.
Happy Electric Bill.
