The analogy also extends to racing.
Many automotive companies use racing as a promotional tool along with being a proving ground for new technology. Technology that would be wholly impractical and too expensive to sell in the consumer market. (well, not to mention not street legal in most cases). Honda had very early on pushed the idea of using concepts used for racing to be applied to production vehicles. And it is that philosophy that has propelled them to be a market leader. Spending money upfront on R&D is good for the long term of the company. Far too many companies these days (not only car companies) focus on "me too" marketing. The companies are driven by marketing and not design and engineering. Say all you want about Sennheiser, I guarantee you that marketing did not push for the Orpheus or the new possible Orpheus II. They are more concerned about the possible immediate seasonal sales figures and what color it will be.
Marketing has no place in design and engineering, and I've seen it put many companies down the sh1tter.
But the pushing the envelope is what creates true innovation. And much of that technology trickles down to mass production level products with far more bang for the buck. But the fact of the matter is, that they would not exist without the "flagship" models. Compare this to companies that have a "flagship" model that is simply more of a collector's item rather than an innovative product.
It is a shame that many companies have simply discontinued or put a halt to advancing headphone technology (coughSonycough), and would rather keep selling their "glory days" headphones rather than push the envelope. While this makes for collectors drool uncontrollably, it jsut drives the prices up.
Of course, we never know if they are secretly working on something. (we need our Head-fi moles to be in more places.)
But bravo to Sennheiser if they are release a new flagship model.
