I would also point out as a marketing strategy for high end goods, charging a premium on customization is common and makes sense. You want to price the basic model to be within reach to as many as possible and then to add a high profit margin customization for those that are less sensitive to price.
I'd also like to point out among the general public spending $10K on a set of speakers would receive all the criticism the Wilson does. Many peoples perspective here comes from their own net worth. I'm just guessing the average net worth of the folks here is not over $50M. If it were, I suspect the criticism would go away.
