Ok, the T4 is both gorgeous and interesting. I think @dsavitsk needs to sod off with all this temptation. Given his track record, I'd love to hear this  (though I'm unlikely to see one kicking about in the UK).

The  prototype T4 sounded amazing during the ATL minimeet.  Has it got even better?

Yes, it's better.  Better output transistors and more powerful transformer mounted off of the PCB (less noise).  Also, the tubes we had at ATL were a miss--match with the amp configuration at the time.  I think it sounds very, very close to the T5 from the year before: maybe a tad less soundstage, but better tonality, deeper bass with the same microdetail up top.  At the same time, Doug's design with the PCB and packaging - especially the thermal bar - means the entire amplifier is much more robust than the T3.

This is the guts of the production version:
