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

Pillium and Dieses. 

I had to chuckle when I read this. We operate a small service shop that also resells some vintage gear. We do however carry a little new audio, and exactly two brands! They are Rega and Fyne Audio. They have both been a great fill for those who either don’t want either a vintage, amp, or speakers, or just want all new. Very pleased to offer both.

Wilson Audio & PASS Labs. 

Well not so much of a thought experiment.  Once Linn/Naim dealers dotted most western cities around the globe.  Quite a few still exist.  Between the two they sell every component known to the contemporary Audiophile.
