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


Thought experiment:

You run a store which sells used and new gear from any point in history.  The catch is you can have exactly 2 brands.  One of electronics one of speakers. 

Defunct brands are OK as are those current with long histories. 

What brands are they?

Rega and Technics if I could carry ALL of their audio models

Both brands have complete lines, including CD/Digital, turntables, amplifiers and speakers. They have options at all price levels, from moderate to premium to expensive.
