Great info Jolly.  Ive dealt with Audio Arts in NYC (Thoress dealer) before and Gideon is a pleasure to do business with. I might just have to inquire about the F2A11 or 845 Thoress Integrateds.....not a 300B kind of guy.
@jollytinker,
Congratulations on your excellent outcome.  I recall reading the 6 Moons review of the Thoress amplifier.  No doubt about Srajan Ebaen's admiration for the unit.

@jollytinker I'd be interested in hearing about your room treatments.  I have a smallish room and have been researching same.  Thanks.
@cal3713 thanks for pointing out the typo! I should've checked it. 

@stephendunn  I'll keep you posted as I make progress on the room treatment. I'm trying to be minimalist about it because the room has to double as a living room so I don't want to overwhelm the space with audio gear (though I probably lost that battle already...). The main issue is that the room has 10' ceilings and big windows so there's quite a bit of high frequency ringing in addition to the usual low/mid boominess. I put a 6' piece of homasote board on one large, empty wall which helped calm things down. Also I bought a few pieces of 4" thick rock wool insulation to experiment. Last night I put pieces of the insulation at the first reflection points and that made a noticeable and positive difference, more so than in the back corners, but it also felt a bit overdamped to me. So I can see the point of products like the Stillpoints Apertures that do a mix of absorption and diffusion.  

btw I didn't mean to sound too fanboyish in my previous post - just thought the EHTs deserve a mention and i'd love to hear from anyone else who has experience with them. They're the only Thoress amps I've heard and they're the kind of component that just has an certain "rightness" about the sound.
