Thad, to be fair, one underpinning of the audiophile hobby is the pursuit of overengineered systems. There is a certain soul satisfaction in running a piece of equipment that you know is built really well, and has been showered with a lot of attention and care by the manufacturer. Sometimes, it is a joy to just own a good piece of equipment that is built so well, and the primary purpose even becomes secondary or incidental. I would imagine owning a good mechanical watch would be one example.
Another example (not sure why I tend to use analogies so much - guess it makes me think more clearly). I recently helped a friend buy a monitor. Now, monitors are dime a dozen from cheap Korean panels to Dell monitors that are quite decently built. However, if you start looking beyond the obvious and look for real quality, the choice becomes surprisingly narrow, and the price becomes surprisingly high.
There was NEC and there was Eizo. Arguably, Eizo is the benchmark - they still have the old-school Japanese ethos of fanatical attention to detail and obsessing on over-engineering their displays. All their monitors are still made in Japan, not China. They are considered to be the benchmark because they achieve near perfection in terms of accurate color reproduction, supporting the entire color gamut, and uniformity of color and contrast in various parts of the screen. Their professional range does start at $2000 though and it only goes upwards.
NEC actually gets very close to Eizo in terms of picture quality, and in most cases, is less than half the price (still expensive at $1000-$1500 though for the PA series). However, there will still be plenty of people who will swear by Eizo and spend the money - despite the higher cost. Well - we ended up buying the NEC PA series monitor.
With an audio system that we are assembling by hand, piece by piece, we often want the same level of over-engineering in all components to avoid the "weakest link" theory. The pursuit here is really to end up with a "balanced" system with components that match each other in terms of performance and build quality. Of course, balanced systems can be achieved at various price points.
