How much better are MFSL disks?

Like most things in life, MFSL LPs are better, merely different, and sometimes worse on a case-by-case basis. It also depends on whether you are comparing an MFSL to an original pressing or a reissue. Yes, they have excellent resale value, but sometimes they don't warrant it intrinsically. Good listening!

That is broad question so I will answer it this way. As a general matter I have found MFSL disks (assume you mean LPs not CDs) much better sounding than the average retail pressings. That said many titles that were issued by MFSL have since been reissued as 180, and 200 gm reissues or can be found either as Japanese or European imports. There are many previous threads that discuss the quality of various reissues including comparing them to the MFSL pressings.

I own a number of MFSLs, some gold. As my system improves they sound better and better

The sound quality varies from disc to disc.My Hotel california is amazing where as My Crime of the Century is not as good as a Canadian Audiophile pressing I have. You now can compare MFSL with various versions from Natalius and other specialty pressings like DCC and others.

its all about the masters
