Mobile's orignal approach was to not apply an (re)equalization when transferring from the master tapes, whereas most (all?) "regular" versions were typically equalized for the perceived listening preference of the audience or radio play or to actually make up for some weakness in the two track master, as I'm sure you know. The MF idea was faithfulness to the original. This often made for an awesome result, but sometimes revealed undesirable characteristics of the master. I don't know whether this approach continued into the CDs, especially the more recent, or not because the technical direction of the company certainly changed hands.

I have heard several of these cd's and have been very unimpressed. They are slightly better then the originals but not by much and the general over all quality poor. The only good ones I have heard are Pink Floyed which are great to begin with. Am I missing something? Did I just happen to not hear some of the better ones?
