You mean Caliburn, Boulder, etc, attempt to hold DOWN costs? I don't believe it. Or rather, I believe they attempt to hold their costs down, but not the price tag to he consumer. At a certain level (and maybe at lots of levels -- $2k/meter cables? -- the far and away most obvious selling point is just how damned expensive the product is compared to the alternatives!), higher price tag is what the consumer WANTS, and helps the sale. So the very highest cost/end manufacturers wouldn't, I think, hesitate to supply whatever they felt would induce the illusion of the truly best performance, including supplying dedicated power cords and electrical outlets and hosts of other "tweaks".
Some audiophiles always modify even their expensive gear because they are tweakers and want something unique, plain and simple.
