The Dylan Original Mono Recordings box is a must have IMO. It’s consistent and well recorded. There’s a consistent theme running through every lp and that is how natural the music is forthcoming. Great mid-bass/ bass. It is the essence of analog.
The MFSL/45rpm/mono version builds on that great foundation. It doesn’t over-hype anything. There is just an increase in dynamic range and resolution. I could easily live with either version. I’ll gladly live with both. BTW, first time ever hearing a mono lp @ 45rpm. Wonderful!
