It wasn't an engineer. No engineer would say that. Most likely he was a marketing wonk or similar pretending, just to get rid of the "annoying caller".
I've read and seen some interviews with the boss of Rega, Roy Gandy. He is a really interesting guy. Background in mechanical engineering - he started building a turntable as a student because he couldn't afford to buy it. He describes himself as
"unwilling capitalist, unwilling boss, unwillingly running a company that I'm very very proud of"
He is very very much not interested in the money side. He seems to see the business side of Rega as a necessary evil to support the people who work for him, and to allow him to continue to develop kit that he loves. His main motivation seems to be listening to music in a format that pleases him (paraphrasing here, because I can't find the exact quote) "in my (our?) world, somthing about the recording and playback of music on vinyl brings something that people prefer the sound of"
One such interview is here:
