speaker choice for new 20x30 audio room

I just went through a similar search.  My musical tastes are also similar, as is my room side (13x30 in my case).  I found Audiogon and other sites quite helpful in narrowing down my search and can see you’ve already gotten a some good recommendations.  But, and I strongly encourage this: select a few speakers or brands; then get out and audition them.  I really didn’t want to take that approach at first.  I ended up taking 4 different trips—or 15-20 hours of drive time before I found what I wanted.  In hindsight, it was incredibly satisfying.  I started with the goal of finding the perfect speaker for me, but ended up learning a ton about room treatments, proper set up, etc.  I also met some incredible people, learned about their interests, shared stories of amazing concerts they attended, and finally found a speaker I’ll be happy with for quite some time.  Life is a journey….there are rewards sprinkled along the path you travel.  Best of luck to you.

Give the Golden Ear Triton 1R a listen.

That is a huge room. But how close to the speakers will most of your listening be done?  Ie if you are going to be sitting 10-12 feet away, that is a huge difference from if you would typically listening from 20-25 feet away.

And it sounds like your top budget is $10K? Then I'm not sure why you're getting suggestions for the $20K range. 

Sounds like a perfect sized room for a nice used set of Klipschorns. 

whatever you do make sure you don't buy those bright sounding paradigm persona speakers from audio Troy they make your ears bleed that beryllium tweeter and mid-range are so bright it's not even funny.
