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

Same thing I sold back in the mid-1970's - 1990's:

Audio Research and Magnepan

That's about all you need for the major components if you are actually interested in accurate reproduction.

Of course the OP premise was silly, but he asked a question, so give an answer or move on.

You all remind me of people who can't simply take an idea and run with it rather than spending your time tearing it down and ridiculing the person and the concept. I worked with a lot of you all at the large computer company I spent my career at after selling my "high -end" audio shop.

Some things are just simple and straight-forward and don't require tons of dissection and discussion.  Either name the two brands, like most of us did, and move on, or take Bambi's mom's advice.  You remember Bambi, right?

Oh, my, he was not REAL, so let's not talk about pretend cartoon characters.  Harumph!  This is a SERIOUS Forum!  We only deal in measurements and numbers and quantifiable information that noone except a PhD in physics and acoustic theory can discuss.  (Joke's on you. In audio, purchase is usually based on what YOU like.)

Good grief!  Has light humor left the planet during the previous 4 years of total insanity?
