Saturday Afternoon at the Opera, often live, from The Metropolitan Opera

I don't know about WQXR. I listen via CBC FM 105.7 way out in the Vancouver area in BC.
I agree about coughing. It seems many modern audience members don't really have a deep appreciation of the experience available from live music with the incredible effort and tension of players trying to make every presentation an "ultimate" performance. I feel if anyone comes who's likely to cough or sneeze they should take medicine,use lozenges and bring heavy muffling in respect to all.

I haven't been to the Lincoln. I consider myself fortunate to have this quality of live Opera,and the interesting commentary,played over my system, and have never found cause to consider any technical/acoustical quality. Perhaps due to the placements of mikes for the presentation the effect of hall acoustics is significantly diminished?
