The "market distortion" aspect as suggested by @hilde45 has merit in my opinion. Here’s this audio market where everyone plays nicely and introduces "new products or new versions" with incremental price increases of, say 10%-20%. Then, out of nowhere some manufacturer has the audacity to take that metric and increase it by a factor of 2 over previous "norms". This presents a number of possibilities for other manufacturers. The "sticker shock" of their top end products is has been obliterated by another company (thank you!) so their products appear to be a more reasonable cost/performance value. So, they would feel justified in raising the price, not just 20%, but 40% and still be very much in line with the perception of high performance AND high value. So, yes, a market distortion could follow the introduction of steep pricing into the marketplace.
A little about the luxury market: Centi-millionaires, traditionally, don’t loose sleep agonizing over whether or not they received strong price/performance when making a purchase.. They are primarily concerned with owning something that really IS something worth owning. Sure, they’ll brag about the "guts" or "workmanship", but their true motivators may be the intangibles that can’t be measured. What is the prestige in owning the best of the best actually worth? And, if it IS expensive, wouldn’t it be viewed as a badge of honor rather than a shockingly high-priced trophy?
Customers are also different. Many who engage in the ultra highend of a product category are true enthusiasts who love what they are doing and appreciate every nuiance their extraordinarily expense product does for THEM. They ARE getting great value from something they have heavily invested in.
Back to the marketing considerations, I think we could look at various price ranges to see if a significant and meaningful gap exists whereby a segment of the buying public is being ignored, or has been abandoned altogether. As a result of that 2x product introduction, is there still a healthy market for legitimate high-value products at 1/2 that price, and somewhere in between? IF that 2x product negatively impacted the viability and availability of those other (lower) price ranges, then some measurable damage has been done.
