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?

Did somebody say Carver and Energy?
Damn ! Are you a brother from another mother ?

Spot on , man ! LOL !

The real answer is which two brands give me the highest volume of sales as well as profit margins and which companies back up their products. 
The OP did not say the goal of the subject matter was to select the two products that would be the most profitable. Suppose you are independently wealthy and opened the store for personal enjoyment.
In that case I would select two products that I would enjoy selling and have confidence in their quality and musical enjoyment.
