I think the HCA2 is an older version of the Class D technology, no? It looks like the GCA amps are using the new ICEpower stuff though:

I'm guessing the GCA500 has the 1000ASP module.

On price, see the link I posted above -- 1000ASP modules (both channels) in a box, for $1,375:

That's just incredible. Look for the fancier high-end sellers of these things (Jeff Rowland, Bel Canto, etc) to start dropping their prices too.
