High end audio is a purely discretionary, luxury oriented market. If you have to lease or otherwise finance your purchases, then you might want to consider that you cannot actually afford what you lust after. Also, why should the manufacturer gamble on what the depreciated value of their product will be a year or two after purchase?
Should manufacturers lease speakers?
Given the turnover of equipment, maybe it would make sense for manufacturers or dealers to (profitably) lease speakers (or other components for that matter) with an option to buy? I certainly would be willing to pay to live with something (espescially something expensive) for a year or so knowing I could return it without the hassle of selling.
