Sounds like maybe he is just trying to help the everyday man get better sound.... not undermining "audiophiles"?
I would assert you do NOT have to be an audiophile these days to get top notch sound. Future Fi gear like all-in-ones solve most all of the system building problems for people. Then its just the usual things, tweaking the sound in the room, choosing speakers, etc. to one's personal taste. Most people are not in the hifi olympics looking to win gold medals at any cost.
I’ll take a look if I get a chance and see.
@mr_m having seen the material, what is your assessment?
