45RPM reissues: are better 180g or 200g?


Hello friends,
I'm buying the 45rpm's set (4 lp's) of LSC 2449 (Gibson/Bizet Carmen-Gounod/Faust); it's available on 180g and 200g reissues (both 4LP's, one side pressing).
What should be the better choice, in terms of sound quality? Why?

Much debate about this, Eziodoc. When Classic Records started pressing 200g LPs, they had quality control problems because the presses used to manufacture the LPs were designed for up to 180g, not 200g. There apparently were issues with fill rates into the stamper and many people reported that the 200g pressings had surface noise. As a result, the 180g pressings have sold from time-to-time for a bit of a premium over the 200g pressings.

FWIW, my copy of the LSC 2449-45 Classic Records 45rpm reissue is the 200g pressing and it sounds superb. I do not have a copy of the 180g pressing of the 45rpm, so I can't compare.

Overall, I've had excellent results with the 200g pressings, and I have not experienced any of the problems reported by others. But I just consider myself fortunate and don't doubt that others have had trouble.

Classic Records certainly believes the 200g records to be superior to the 180g records and theorize that the greater weight improves damping of resonances in the vinyl thereby allowing for a higher resolution playback. There have been reports of demonstrations during which Mike Hobson (Classic Records) played various pressings of the same LP to demonstrate the sonic improvement provided by the 200g iteration. I have no first hand experience with any comparisons, but this is the only way for anyone to develop an opinion of the sonic results. Comparing 180g vs 200g pressing different recordings do not tell us much, and I have some of both.

I have several of the 45RPM jazz pressings from AcousTech, part of Acoustic Sounds "Fantasy 45" series and they are all great. The Count Basie are hard to over sell in terms of pure sound. In summary, I would say these are the best sounding LPs I have ever heard.
