An alternate to the ICE module is the TriPath module, for which, unlike ICE, there is a good bit of technical info available on the web. Naturally, the TriPath folk say their approach is best, as do the ICE folk. IMHO it probably depends on what you wrap around the digital control module.
I use CarverPro ZR1600 amps which cost less than 1/4 of what you would pay for H2O or Spectron. The ZR1600 is darned good, and supposedly if you mod it, mostly by bypassing a bunch of input circuitry for pro sound applications, it rivals the best.
