I grew up in Albany, NY. A ton of hifi shops have come and gone over the last 2 or 3 decades. Only one has stayed.
Hippo's does things unlike most hifi shops I've seen. They actually advertise in print, radio, and TV. They carry one or two big box brands to get the average Joe's attention, like Sony and JVC. They advertise that stuff at a few bucks less than the big box stores (a Best Buy is about 5 minutes down the road).
When the average Joe walks in, they have to walk past a few McIntosh, Rotel, and Cambridge systems to get to the Sony stuff in the back. No one walks by a Mac anything without noticing it.
They don't bait and switch. They audition stuff like KEF and B&W against near equally priced Sony stuff. They show what a few more bucks will get, and what a few bucks less will get.
They do a lot of HT and stereo sales. They also do a ton of custom home and business installs. And they've embraced the iPod and DACs, rather than fight them.
They have a very knowledgable, non-snob, non-teenaged staff.
These things sound like common sense, yet how many dealers have actually done anything resembling this?
