I think one is always paying a hefty premium for "statement" design and esoteric materials with a "luxury" product, not necessarily better performance. As a subscriber to the FFF ("Form Follows Function") philosophy, I generally avoid such products.
When the function is audio reproduction, the visual aspect of the equipment, including design, fit and finish, and "unobtainium" materials may contribute nothing. Given the same level of performance, I will generally choose the less expensive product over the more expensive prettier one. However, if the more aesthetically appealing one is priced only marginally higher, I will sometimes pay a little more for that, but not so much an order of magnitude.
