mfsl vs. classic records

It depends largely on the recording, what tape masters were used and the quality of the pressing run; I've had both good and bad luck with both labels with a slight nod toward MFSL for generally better results in terms of noise free pressings. It's still a bit of a hit or miss world when it comes to quality vinyl but satisfying when you find good pressings of desired performances.

I agree with Stevecham and would also add that there have been significant differences within each label's time frame: for example, early MFSLs were pressed by JVC in Japan, then their UHQR and GAIN. Classic Records also went through various vinyl formulations, etc.

I think, subject to someone else with better knowledge, that generally pressing runs were about 5,000 for each/both? companies.
