You have a wealth of concert hall experience. I love the mono recordings on Mercury of Rafael Kubelik + Chicago SO in Orchestra Hall (I guess renamed Symphony Center). Have you tried a few locations there to compare the recordings with what you hear live? Boston Symphony Hall was great in the 4th row center when I was there 2016. I heard the Boston Philharmonic Youth Orch conducted by Benjamin Zander. Zander is a world class conductor, so the best deal is hearing an excellent student orch at their best with a great conductor. White fluorescent lighting was used. The tonality was clear, cool and neutral, unlike the warm, HF rolled off quality in Carnegie. Sensory perception overlaps with sound and vision. I wonder if Carnegie used cool white light, whether the tone would then be cooler and less warm than it is.
In the Concertgebouw, I sat in about the 10th row center. Muddy, syrupy warm sound. This correlates with what I hear on recordings from European halls--distant and muddy.
Prices are insane in major famous halls with famous orchestras and soloists. People who are willing to pay $700 for the balcony in Chicago have no idea what details they are missing vs much closer to the stage. My strategy is to get a modestly priced seat on the main floor as close as I can get. 5 min before the start, I survey empty seats, and then 1 min before the lights dim, I dash for the empty center seats much closer. Acoustics don't matter much to me, since I want the maximum detail of the 1st row.
