analog newbie question/vinyl weight

Rushton, wonderful post. I actually have some 104g (Telefunken) records that sound surprisingly good. Yesterday I played a new Cyprien Katsaris/Liszt LP and was worried the record would be too thin. Yet the piano tone was decent and the dynamics were certainly uncompressed. Elizabeth was right, choice of mastering techniques and other variables matter more than the weight of the vinyl. OTOH I'm reasonably sure I heard some intervinyl resonances that might have been better damped by a thicker record.

has anyone taken measurements of 120,150,180 and 200 weighted lps in inches curious as to what those measurements really are.

Mine are all 12" across, plus or minus a twidge. ;-)

Yes Doug i guess i m being just a little to anal on the scientific end instead of the end that counts
let the force be with you Luke.

Kind of tough to measure with most LPs having that ridge at the beginning of the LP.

I'm too cheap to buy one.
