I thought of this while watching Daredevil when we are in Fisk's Penthouse. There was classical music playing, but we never saw where it came from and I was thinking how a pair of KEF Muon's ($185,000) would look about right in his mostly metal decor:
It would certainly create some buzz among fans wondering what they were and what type of gear a wealthy, refined (but ethically-challenged), power-monger would possess. It would put KEF on the map (I would venture most Americans have never heard of KEF).
We have seen that Hollywood has started making a few extra bucks by inserting "advertiser's" products in a film. The cool car, the brand of beer drunk, store front in the background, etc.
Seinfield had a Klien bike hanging in his apartment (don't know if he got paid for it, but it didn't hurt Klien's bottom line).
So, I am wondering if you have ever seen specific HiFi gear in a TV show or movie.
