Yes,there were very few MC Reference preamps built. The 9 pin successor to the octal based Luminescence. Will try to upload pictures. I have recently moved and the system is in hibernation during remodeling. Those are cut down Sound Lab A-3. I was having problems with too much reflected treble of my 8' ceiling,so iI chopped the SL's bottom casing off and built a seperate box for the crossover.electronics. Glad you like.
Wow! I heard the legend of MFA - MC Reference but never actually witness one in real life. How about posting some pictures? BTW, are those Soundlab speakers?
