You own a store, you sell 2 brands, which?

Bose & Sony was a good pick Duder.   everyone knows the line.  It's people picking the likes of Audio Note.   2000 people looking to buy a 7 k. audio system  would walk right past the Store .  It's like Tidal HiFi  I've asked a lot of
people all ages about it .  No one knows what it is  except people reading audiogon 
 How many read it 

Too bad the OP didn’t specify a timeframe.

Storefront 25 years ago would probably be McIntosh and B&W.

Good luck to anyone trying to run a store today.
