Speaker brands known to use first class internal components

Being obsessive usually ruins the pleasures of life.

I do get your point but I'm glad nobody convinced Louis Pasteur of of this when he was developing a cure for rabies which up till then was always fatal. Or convinced Thomas Edison to quit obsessing over that light bulb thing. "Tom, what's wrong with candles they work fine" 
None of this is meant to be mean spirited. Some of us are just tinkerers and try to improve a lot of things we have in one way or another. Back in the 80's and 90's Mustang GT's and Cobras came with wimpy 2.73 or 3.08 gear ratios to please the regulators with higher CAFE mileage ratings. For a measly $400 or so putting in a 3.73 ratio would have you think you had an entirely different car. No comparison. I think a lot of us just try to channel the 1% we have of what Henry Ford had in spades. I know he was an SOB but that's an entirely different story

Maybe a better question would be "well known brands known to use junk parts off the five and dime shelf". There are quite a few ’high end’ companies that do fall into this category, many that would surprise us!
Whether these folks should be ’outted’ is also another good question?
