So do you have the same opinions when it comes to buying spark plugs, alternators, dishwashers, outboard motors, airplanes, cars, motorcycles and pianos. There are many companies with cross channel marketing and functionality.
I made my basic stance clear above, but to be more specific, I don’t think that anyone is suggesting that it isn’t possible for a company to be versatile, and to make a variety of different components of similar quality, but broadly speaking, focussed companies are, as a group, likely to be the most reliable sources of high-quality products.
I expect that, to name just a few, Gryphon, SimAudio, and Bryston produce high-quality DACs. But at the same time, I believe that the best and most innovative designs are more likely to emanate from companies that are focussed exclusively on DAC production.
And I would expect that the same is even more true of speakers, given the differences between their designs and those of electronics such as amps, transports and DACs.
There may be a restaurant somewhere that serves fantastic sushi, along with pizza and hamburgers. But when I am in the mood for the former, I seek out a Japanese restaurant, as I expect the odds of a good meal to be much more in my favor.
