Pavlovian. We enjoy listening to music and shopping for gear, so the smells associated with those experiences elicit the same pleasure sensation
Scent of an Audio Store
Literally. I have always found that to be a remarkable, intoxicating thing. Scent of fine woods mixed with heated electronics and new carpet. The more speakers they have on display, the finer the scent. It smells unlike a furniture store.
I wouldn't be surprised if some stores used scent marketing to lure audiophiles, many brands certainly add a scent to their products and packaging materials.
