Muddy Waters from Classic Records

This is a kind of view which is right. I personally agree with that. I have better things to do than buying the same titles 5 times, too.
The Muddy Waters was always a record which I really liked, but the MFSL was always like a fist in your face.
Both say, they used the master tape but the results have nothing in common. I always thought, manipulation with CD is quite normal and master tape is like it is.
Seems that I was wrong or ?

Sorry I forgot the question:

How is this possible, that from the same Master tape can be such results ???
I always thought, these MFSL records are super, but the Classic Rec. really impressed me.

Got today the Muddy Waters Lp from classic Records.
Normally I do not write about software, but this one is unbelievable good. I have the MFSL and this one is spectacular, but more or less only good enough to impress a listener for your system.
But the mastering from Bernie Grundman is definitive. A real killer, a tour de force through dynamics.
