Armistice,
Your CW80 appears to have been spec'd along the lines of the "Stage" series or from memory the "Messiah". I strongly doubt that the gloss finish will have any bearing on recorded sound. I have played Matons, both gloss and satin and any difference in sound is so subtle that it isn't an issue.
I have found that in general terms, as you progress through the Maton range, the guitars have a fuller, more resonant projection of their sound, which I think is to be expected as you will find slight increases in body size and higher quaity timbers being used. Obviously, the prime object in their design is to perform as an acoustic and I suspect each models recording characterisics were not a major concern.
For the record, we have 5 Matons here.............an old "Alver" arch top which I've had since about '64, a CW80/12 ......April/69 #275 which I purchased new for $151.25, an ECW80C/6 ......April/95 #8052 and my Son's EM525C and JB6 electric. Additionally we have both 225's and 325's that are here frequently.
Finding a sweet spot for micing the CW80 is going to be more difficult than any of the lower models simple because of the nature of the guitar, BUT given the choice of owning a 325 or an 80 and I'll pick the 80 any day of the week. They are just "that much more" of a guitar

.
If possible, have someone play the guitar and while they are, move around out in front, preferably with just one ear facing the guitar listening for those sweet spots...............move in close and further out, ALL around, top and bottom too. Try and remember how it sounds at different positions as what you want to hear recorded one day, may be different for the next song.
Good luck.
