Muddy Waters from Classic Records

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.

This is exactly why this hobby is dying. To re-fi MOFI is rediculous. Does anyone really need anymore versions of Folksonger? Did anyone buy the DVD version by Classic? An excellent album indeed but it's a big so what at this point. What are we to expect next, another Darkside of The Moon? Anyone really need a copy now? Why not do other Chess titles even another Muddy (several come to mind). Anyone know why Classic isn't doing more Mercury titles? Why bother going backwards to go one step forward? What can we expect next another Queen Night At The Opera escapade? On 45 RPM?

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 ?
