Saw the NY Phil at Lincoln Center two weeks ago. The band was quite good, but the sound at Geffen Hall is shameful, IMO. No resonance, no bottom. Very, very flat. Supposedly, they're redoing it - again. Carnegie is far better. Of course, where you sit makes a difference, but I allegedly had very good seats, so I wonder if it's better anywhere else in the audience.
But I did have a nice time otherwise.
