I think the amount of available low-cost technology has changed the audio world. A couple of decades ago you had to rely much more on the few main and many boutique suppliers to provide high-quality products, which had to be sold through local brick and mortar stereo/hi-fi specialty shops. The small audio companies had the design expertise, the focus and the passion to build quality equipment. The process was too clumsy and unit sales too low to make it worthwhile for most larger electronics companies, so they tended to put our cheaper and lesser performing stuff. The gulf between the two sectors was obvious. Today, with the ubiquity of ICs, computer chips, DACs, Op-amps; inexpensive robotic production (especially overseas) a company can make top-grade equipment and sell it via the internet, cut out the middle man and absorb the middle man's margin to make it work. The gap between companies has narrowed if not closed. Topping can put out a DAC at $300 that will have world class performance and a miniscule gap, if any, to boutique companies that charge far more. Good for the consumer. Maybe not good for U.S. audio producers. Such is the marketplace.
