I'm in complete aggreement with wdrazek. Innovation has been, and will continue to be, from the high tech community. The high end sector seems to see itself apart from the digitization driving music, choosing to sell to the installed base. As a result, their profit margins must continue to rise at every tier, as they sell to less and less customers. Hence we see the $50,000 amplifiers that cost a tenth or less than that to produce. Meanwhile, Apple produce a computer and sells it at a 40% profit margin. The computer industry has given us wifi at low cost, iTunes is free and is incredible, Soundengine make some great speakers at insanely reasonable price; the high end sector cannot, or maybe choose not to compete.
Meanwhile, the high tech industry focusses its attention on this mass of music lovers and products like the squeezebox, Ipod, music servers and the like raise their heads over the decomposing carcass of an industry that chooses not to evolve.
