I feel your deflecting a little with the auto example. Were talking stereo equipment.
My perception is most company have entry models. Look at MSB. Look at Magico. Don't Magico still Sell the A1 to A5? I honestly don't know. Mike would know a lot better.
I have at times wondered, what fills the bottom line with these companies. Is it the few sales of really expensive pieces. Or is it the many less expensive items.
As a business, oddly, they are all trapped in a cycle I can not say they started. Us people desire new. We want to own what we feel is relevant. Or the best we can afford at our budget price. Owning a piece from a company that has not put out anything new for 10 years would probably be owning something from a company that is out of business. Being forced to produce new and better requires man power ($$$$$) and capital investment in equipment ($$$$$$). Its possible. I don't know, but its possible, even with the inflated prices of equipment, many of these companies may be struggling. I don't know. Most are not public. But we have seen some collapse. Dartzeel, MBL. Aren't there more.
Being Wilson and all the hype over the Autobiography might make buyers think, WOW. This company makes the best. Then they go to Suncoast Audio and get a set of Sabrina. And maybe a use pair of Ref 250 to drive them.
