My Krell dealer used to let me buy Krell items at a decent discount, and return them a month or two later if I did not get value from them, no penalty. When the amp blew some capacitors. the dealer's technicians fixed it in his workshop. But that dealer is pretty special, rated in the top five worldwide.
These days he still operates the same expensive listening rooms, but his bread and butter comes from home theatre.
The market is highly competitive. Those manufacturers best placed to survive, in my opinion, have volume mass-market offerings plus flagship high-end products. Sony and KEF spring to my mind.
Price is rarely the most important factor in any buying decision. Just look at the variety of cars people buy.
