I was lucky enough to play a small part in testing these models as they were made against the source mics and I can happily say that great care and precision goes into each model analysis.
Although the original vintage mics have inconsistencies that aging components accumulate these models sound like a brand new production of each… and if you want to get them so you really couldn’t pick in an AB test there is a simple little trick- but you should have the fun of working it out for yourself, and there is no need- these models are worth every penny.
