Have you ever designed/built and sold successful products to the public?
@soix - I know sometimes it's difficult to look past the person based on their comments and interactions with others, but George designed and built the Lightspeed Attenuator which I've owned for over 10 years and consider one of the best values in audio. Quite a lengthy thread about it on this site and an entire DIY thread on it elsewhere. So in addition to designing and building it George has shared it with the DIY community.
As far as who knows what around here, Ralph's knowledge and expertise in this field is a given. I've owned his products for over 10 years as well. After reading several posts by Ric of late the kindest word that comes to my mind is: meh.
