Installers of home theater system's or horribly insensitive to sonic quality. The components to use tend to be second rate. But they may offer a pretty appearance at the end of it all. Always wondered why people invest so much money in a home theater room when it's typically not used very often. Regardless of how wealthy they are
In fact service from a high end manufacture is often better because the dealers tend not to know much about the products they're selling. If their product doesn't exist in a Store then what value does a retailer have for higher end components. Although they may still offer a better deal then a manufacture which is bizarre. Manufacturers will need to be shaken up and reduce their prices and maybe increase the volume and maybe stay in business.
Never mind the increment of value sonically for a component costing $15-$20,000 more then a mid teens product which is still pretty damn good.
