I equate the audio gear I own to tools. There is a certain special satisfaction one derives from having the exact right tool to achieve a particular outcome. Just as a chef will have a number of knives from which to choose for a specific cutting task, there are certain audio components that are able to perform the task they were designed for in a manner that is superior to other similar components. And while it is possible to make radish roses with a cleaver, a paring knife is probably the most appropriate tool. As well, the stamped Forschner paring knife will get the job done, but the forged Sabatier gives a certain elegance and satisfaction to the task. The pursuit of finding the forged for the stamped price is another type of contentment that is appealing. I hope you find this analogy appropriate.
Enjoying the music is an entirely different emotional and subjective experience. Using the previous analogy, its akin to enjoying a meal on its gustatory merits.
I enjoy both aspects of the hobby without guilt or second thoughts.
Life without MY audio system would be far less interesting.
