Anyone hear Linear Tube Audio Prototype mono-blocks?

Hi Fellow Audio Fanatics -

I understand Linear Tube Audio has a new mono-block amp they demoed at the Pacific audio show in late June. Did anyone get the chance to hear it?

I have their preamp which is wonderful. Was wondering how this new 120 watt product sounded like. I’d love to hear impressions from anyone who had the chance to hear it a few days ago.
