I find that a hard choice to make. The main reason being a good room will be more revealing of the inherent weaknesses (primarily polar response and resonances) in a low quality speaker. So you end up with a great room and it shows off how bad your speakers are

.
Yeah, but c'mon... to a point? Seriously. A 1k pair can sound quite fine, if not BW top-end level. IMO, I guess they would sound or measure much more similarly in a good room, VS BWs in a terrible room and (Sierrra-1s?) in a good room. Yeah, even missing low response, I'd still take the latter. In fact, Im positive the latter would blow the first combo away going by the two rooms Ive tried for my stereo this year. Yep, I also brought in 300 lbs of treatments into a BR. It was impossible. Just going by the acoustical nature of this awful room, and no I don't need a single damn measurement to tell me this is the case, because yes its that bad, I am 100% positive that 802Ds will sound like crap in there. I'll repeat, I heard 802Ds in a room that was so awful, I asked the dealer if the tweeters were blown. That bad. It was a dedicated room too. Krell monoblocks powering.
I would easily take a pair of Image bookshelves, or Ascends, or MA entry level stuff in my living room, which in of itself is not necessarily an acoustical dream either.
Then again, I am crazy...

Here, you have absolutely no argument.
OK, to make an analogy. I'd rather drive a Subaru on a nice winding road, than a Ferrari on glare ice, if I could only choose one, and that combination stuck everyday as long as I had the vehicle. A Ferrari is a Ferrari, but IMO its only effective when used in/on the proper medium. That's all I am saying.
If you have a nice room, well have at it! I still stand by my thought in choosing the nicer room over the nicer speaker. Even if the nicer room forces a downgrade in speaker choice, for whatever possible reason, I'd still choose the first in a
heartbeat.
