Theta Prometheus Monoblock

Just finished reading Stereophile's review of the Theta Prometheus class-D monoblock amps. I definitely want to hear these amps to see how they would compare to the Bryston 7B-SST2/28B-SST2 which are right at the top of my list for next amp purchase.

If anyone has any experience with these amps please give some feedback and opinions. I have not heard class-D amps too often (Audio Research was the last one I heard) so there is a bit of mystery for me with this class of amps.

I am going to be using a BAT VK-42SE solid state preamp and KEF Blade/Blade2 speakers with my next amps.

I imagine I will be able to hear these amps at The Newport show in a few months.
