Thank you all for the warm welcome. I have figured out there's no such thing as a bad choice when it comes to these amps

just good or best for a particular purpose.
As my speakers slowly burn in, I'm hearing new things in the sound, and it's just making me keener to buy.
The room isn't cavernous by any means. It's not acoustically very good either, being an odd shape. I've uploaded a wireframe for fun - as you can see it's a bit messy acoustically, and rearranging it would be good, but I really want to stay married

Ceilings are 8'. My gut tells me from a power perspective, any of the amps would work.
Any comments appreciated. Oh, and aside from cold calling and trying to pull Steve away from his work, what's the best way to get hold of him?
