Everything built has to cover the cost of R&D, and all the other costs of doing business. If a company that builds in the US and employees our freinds and neighbors doesn't offer insurance, benefits, and paid vacations we will have a bad opinion about that company. If they do offer all the things we want, we complain that their products cost too much. Americans want everyone to be successful and make a good living, but not on their purchases.
I don't know why a Wavac amp system costs $350,000. I can't justify costs like that, but Ferrari, and other companies who 'hand-build' cars have no trouble justifying, and GETTING those prices.
These are different issues though. Some items are priced based on what it costs to build them (including the insurance, benefits, vacation and all that) while other items seem to be priced according to how they compare quality wise to other items and then there are items which appear to be based on what the market will bear. As a consumer it's difficult to know which method of pricing applies to each item. Perception is rarely truth. Audiophiles need to be cautious when trying to determine what a manufacturer has done and why they have done it.
If it was so easy and cheap to build all the items that people think are overpriced, there would not be so many companies falling along the wayside.
You don't know anymore about how or why Wavac determined that price than the president at Wavac knows why you are wearing that shirt.
I toured Krell a number of years ago. The factory was big, there were maybe 100 people working on R&D, building products, answering phones, and shipping the products, etc. How much does it cost to pay about 100 people, so they aren't running off to the next company once they've been properly trained to do the job for which they've been hired? Good employees are hard to get, just like good audio products.
