The article I quoted was in the post above from @horn13

Interestingly one of the worst positions with a big orchestra (around 100 players - six times more than the baroque ensembles needed for the Brandenburg Concertos) is where the conductor normally stands. It is far too close to the front desks, which overpower more distant players. Our Australian Mahler specialist Simone Young would move around the empty auditorium while the orchestra was on 'auto-play' to try to work out the balance she wanted for the audience. But as soon as the venue fills with people, its acoustics change.
I have never been to the acoustically designed Symphony Hall in Birmingham, but my understanding is that its inner structure floats on rubber isolation blocks. Huge adjustable 'hangar doors' open to the outer space, allowing the hall reverberation to be fine tuned to suit the musical program.
If I ever visit Europe again, Copenhagen 's newish DR Koncerthuset will be a must visit along with the Berliner Philharmonie;
Not to mention the biggest wooden building in the world - Wagner's temporary hall in Bayreuth, the Festspielhaus, which is now almost 150 years old. The hall demonstrates Wagner's intention that the sound should be blended, and some say foreshadows Phil Spector's Wall of Sound. The entire orchestra in the Festspielhaus is under the opera stage and out of sight of the audience. Good luck pin-pointing instruments there!
