I am always amazed that some of the people that design some of the best audio components use some of the crappiest components to drive them with or listen to them from.
This has not been my experience at all. From the shows I've attended, and the hand full of manufacturers I know, I've found that by far the vast majority are very selective about which components they build their show systems from, and about which companion gear/manufacturers they choose to show with. It would not be in their best interests to do anything less, and their livelihood depends upon it. Can you give us a few examples of manufacturers who you've observed using "crappy" components to showcase their own products?
More to the point a cable designer should have both tube and solid state amps/preamps and a verity of speakers to design with.
No surprise that Rodger does not.
What makes you think Roger Sanders has not tried a variety of components in order to form the opinion he has? This implies you know a whole lot about Roger Sanders, except how to spell his name.
My opinion you don't need to respect it, my wife doesn't either.
I'm with your wife.
