Let's see where everyone's true passion is. Where would you rather work on a daily basis, a record store or a HiFi shop?
As fun as it would be to work at a HiFi Shop I think the bore factor would come in quick(er). I'd prefer the record store because of the endless new discoveries/experiences. I'd team up with a local HiFi shop if I was the record store owner, have them donate a nice entry level 2-ch system that shoppers could listen to potential purchases on perhaps. In return I'd donate "demo" discs to the HiFi shop for them to showcase their gear.
So what gets ya more? The music or the gear?
