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. My belief is a good amplifier designer should have experience with a good range of speakers. A speaker designer should have a number of amplifiers/preamplifiers to listen to. 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.
My opinion you don't need to respect it, my wife doesn't either.
