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.
