I had some of the sorbothane pucks around from a previous use. I
set one of those heavy marble pastry sheets on top of them and put
my Rega on top of the marble. It cured the bass resonance interaction
and I think it looks really nice, all for around $60. Sorbothane
pucks were from Audioquest, I believe. Pastry sheet was green marble,
from Mervyns.

It may also have improved soundstage reproduction. But then it may
just be my imagination.
