Any Opinion on DCC/MoFi CD Quality?

Ben said it all. Look at the time when these were released. The MoFi "The Wall" was released in the early '90's (like '91 or '92 I think) and at the time was way beyond the regular version that was out. The remastered version of The Wall, released in 1997/98, is better but that is to be expected. I can tell you that all of the Moody Blues MoFi's are better than the current remasters. If you are in the market for MoFi CD's, you will probably be OK if you purchase anything that is "Ultradisc II" as opposed to "Ultradisc" (which "The Wall" was). Ultradisc II was their "new" remastering system they used in the mid-'90's and was superior to the older system and in the discs I have compared, still outperforms or holds its own against anything out there. But as someone else mentioned, it all begins with the master tape!

I tried to fool myself into believing that these "premium" pressings were superior. When you pay 2x to 8x the price over the standard issue, that's easy to do. The fact is, even on the new Patricia Barber titles, you have to use delusion to believe the MoFi are clearly superior.
My dealer and I have done several of these A/B comparisons.
The remastered "Goodbye Yellow Brick Road" absolutely decimates the MoFi. Ditto for "Double Fantasy".
Those who claim the Gain II process was a significant improvement are correct. They are still a far cry from today's 24 bit remastering efforts.
I am a recovering MoFi/DCC addict. The first step is admitting there is a problem...

I have an extensive collection of both DCCs anf MOFIs. With the exception of John Mellancamp's 'Scarecrow ' they are all vastly superior to the standard issues ... even the remasters. The bass makes all of the difference in the world. The remasters have impressive clarity in the mid and top ranges but are lacking in the bottom end.

I think the MFSL issues also tend to have a somewhat "silkier" sound than most other issues.

The Floyd and ELP releases kick butt on the bass end to be sure.
