I don't know of any video of "the factory" but I went there a few years before Brian passed away. Went there to audition RM -30s. It was just a warehouse of old stock for the most part. Nothing cool about it at all. Filthy actually. Then I went to the showroom to listen to the speakers. It was his garage at his house. Full of audio stuff and junk. Visually disappointing at best. Oh well.
