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

Sony electronics

Probably Magnepan or Tannoy speakers


I'd really like to carry some other stuff, though...

Considering the rebirth of vinyl and nice offerings of speakers and electronics all modestly priced, Rega.
And a very popular and venerable with a wide line of speakers, Klipsch.

Sonus Faber and  whatever other brand doesn’t go through online retail channels.

Coke n Hookers ;0)

Really tough question as there are many great electronics brands that I would choose but very few that also have a turntable line.

Would probably have to second a previous choice with Linn due to their product categories of electronics, turntables, speakers and price ranges.

Speaker manufacturer is an easy one. Vandersteen hands down.
