i've got a rather newb. question. but, it is buggin the hell out of me and after searching i'm just getting more confused. when recording DIN, should the 20 cm spacing be measured between the caps or the bodies of the two mics? the reason i ask is b/c i have a sambra t-bar and have made two cardboard cutouts of 90 degree angles at 20 cm and 17 cm (for DIN and DINA). if a true DIN 20 cm. spacing is measured from cap to cap, it seems virtually impossible for me to get the propper spacing using this t-bar and my 483's.
