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

One brand - Yamaha. I'll be able to sell a whole line of stereo equipment as well as musical instruments, motorcycles and jet skis :-)

Jbl and Msb simply because they are end game units.

In a perfect world, Rogue Audio and Sonus faber. In our world dominated by marketing dollars, MP3 and Boom Boom Bass, it would be Sony and JBL. 

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.
