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?

trick question, there is no combination of two brands that cover all bases for amp, pre-amp, turntable, speakers, etc. 
I could start with Cambridge Audio but for speakers, no brand would satisfy more than 30% of audiophiles. Our ears are different.
For me, it would be Rega and Macintosh.  Rega offers affordable to very good quality.  Also, they have a complete offering.  For the high-end, Macintosh is a complete line as well, maybe minus speakers.  The only thing missing is a very speaker line...
