I have noticed something with pressed 16" records, as were pressed on vinyl
for radio play. They can be rather floppy (cf. Corey's discussion), and I
think I am hearing a good difference when I put a heavy center weight on
the 16" record. I always use that for regular LPs as well, as a matter of
course. Why have the record itself experiencing any kind of vertical
motion as it plays? Nothing good comes from that.
