I use a PSAudio GCC series integrated. It uses the same ASP ICE modules but apparently different input circuitry. Both amps have a single balanced input....#1, single ended inputs, an additional output (to another amp or sub) and the same frontpanel AND backpanel arrangement. Built on the same line, I suspect.
That being said, the 500x2 of my GCC250 is more than adequate for my 1.6s. If, as you say, you are listening at lower levels, you will simply NOT need the 3db offered by the kilowatt model. Also, the smaller module in my amp has a 60 second max power time limit while the larger module limits itself to 30 seconds.
The difference between the W4S and the PSAudio would appear to be the gain cell offered only in the PS amps.
I suspect that interchanged into the same system, you'd be hard pressed to tell the difference.
