One of my favorite quotes:

"It's all junk." - Russ Herschelmann

Don't hang your hat on the product, because that amazing cool new widget that you're so proud of selling today, you're going to have to explain in a few years why now it's time to replace it, and why it's not worth anything.

When I first heard the quote at CEDIA 20 years ago, I didn't quite grasp it. But through the years it certainly has rung true. And as to vendor loyalty to our industry, those are truly rare.

Sell better wiring, speakers and amps, they're going to survive though the upgrades. Focus on separating amps from brains, so it's more cost effective to switch systems later.
