Anyone heard the new PS Audio GCC amps???

Anyone heard, own, auditioned any of the gain-card PS amps out there yet?

I've read the blurb about these at PS Audio's web site.

Is this the same basic technology as the "ICE" module?

If PS can work the same magic that they accomplished with the Power Plants, THESE could be the next "rave" amps in the audio community.
I spoke to PS Audio this afternoon. They are basically just using the same B&O ICE modules that are available from many other manufacturers of digital amps. However, there is an innovation that the volume is controlled directly by controlling the gain of the amplifier itself, eliminating the need for a pre-amp.

But this is very similar to having a CD player with a digital volume control and connecting it directly to the amplifier.
