There are lots of reasons why gear is priced the way it is. Sound quality isn't directly what determines price. Indirectly, better parts, layout, and manufacturing techniques should have an influence on sound quality.
Someone mentioned Bryston and paying for a 20 year warranty. That certainly adds to the cost. Also consider that their gear is hand made in Canada by Canadians making an honest living wage. Paying a person say, $30 per hour plus benefits to hand assemble something makes that unit cost far more than a person doing the same thing in a country where they pay workers less than $30 a day with zero benefits. Having to fix something for free 20 years after its been made adds more to the price than a company who has no responsibility after 3 or even 5 years after manufacture. Two amps that have the exact same parts content and made the exact same way would have very different prices if the only difference was employee wages and warranty coverage.
I'm not bashing Emotiva nor anything else made in places where labor is dirt cheap. I'm just trying to get the point across that sound quality isn't really what determines the cost of any gear, nor the actual value of it. Cost and value aren't one in the same.
I haven't heard any Emotiva gear. By most all accounts it's quite hold for the money. I don't doubt it is. If I were in the market for anything they sell at anywhere near their prices, I'd most likely give them a shot. But then again, I'd rather buy from a local dealer who lives and works in my community. One hand washes the other IMO. No offense intended to buyers or makers of Internet direct stuff.
