He might have been at one point in time. But he certainly no longer is.
I don't want to keep picking on the "cheap audio man" being an "expensive Porsche man" at the same time. But no, I don't think it helps his credibility. I shouldn't be too harsh with him, he's just trying to make some money from YouTube like so many others. If you believe in anybody on YouTube being a neutral expert, really knowing it all ... better think again.
There are those who seem to really believe in what they're doing. That's a good thing, but no guarantee that they know what they're talking about. I don't see Randy in this category, though. His videos are too cleverly produced to qualify.
Randy has just found his particular niche.
