Wow - an audiophile AND a videophile? And female to boot? Somebody call National Geographic - I think we've discovered an endangered species!
<LOL> I've heard that a lot! Especially back in the '70s and '80s. When in a high-end store (we hardly have any more of those in the city), I could NOT be relied upon to measure the "WAF" of various components! (WAF="wife acceptance factor"). I have been a record collector all my life too, which is obviously why I "got into" audio. LPs and CDs have practically moved me out of this small apartment, I've so many.
However, I wouldn't say I'm a videophile on the same level. Video's more complicated in several ways than audio. Or maybe I'm just old and can't learn as quickly as I used to! That's likely. 🙂
Your friend sounds like a lot of the audiophiles (guys) I'd encounter back in the day. They'd talk ONLY about specs and the audio equivalent of the...what did he call it?...video "sound field?" That's all interesting to me, could even wind up being important, BUT...I'd always finally have to ask those guys: Do you actually listen to MUSIC? Or only to equipment?...
A very good friend of mine who was an equipment rep--and before that the best salesman I've ever seen in action--always would FIRST ask a customer: a) What do you want to spend, and b) What are your listening preferences? IOW, he'd find out what his customer wanted (or thought he wanted) and go from there. He would NOT tell a customer looking at, say, $600 or $700/pair speakers that he needs to buy the Martin Logans I mentioned ($21,000 to $25,000/pair) and throw out his Denon amp because it's not good enough and probably couldn't drive them anyway!
I admit I do have Cardas cables pretty much everywhere...speaker wire and interconnects, but entry-level. I have to implement them one by one because even his entry-level line is actually more than I can really afford.
Originally (this was years ago), I didn't believe the hype about cables. It was the first and only time that friend I mentioned and I nearly came to blows! But after living with my Cardas speaker cables for a week or so, I really did hear a difference, particularly after a/b-ing them with the Monster cable I had.
BUUUT!!!...What's important is THE END-USER. There are many factors that go into a purchase. And today one of the BIGGEST issues is: C-O-S-T, and cost measured against the end-user's preferences.
