I'd have to agree.
I know for me, in the classical realm, I'll take a vintage flute over a new one any day. The sound is much warmer, and much better for ensemble blend. However, for jazz, I'd have to stick with my modern Pearl or any more modern flute, just for the extra 'bite' that the newer flutes have. I would say the same for saxes also. I love the way the old Selmers play and sound, and would use them for just about anything I'd play. Still don't have one, but I'll get there someday when 1989 is vintage
