As many threads go, a drift in the discussion leads to solid contributions and good information on a different topic. Unfortunately, only those curious about the thread as it is originally titled,
are exposed to said sharing of information.
If I recall correctly, ETC has been discussed here prior to dragon and local pointing out it's virtues. Not significant discussion, but it's been mentioned. I don't think individuals are scared of the potential complexity, it's just enthusiasts have a finite amount of time they want to dedicate to any one issue of their HT. Obviously, if they'd just get it right once,..and be done,..they'd be golden. However, whatever the topic, many likely feel C+ is good enough,...and they move on to other areas of concern. Ultimately, they may go back and re-visit different system elements representing potential weak links, and hopefully sort them out with a much higher degree of certainty and performance results.
Imagine a logarithmic curve;
The y axis represents performance attained
The x axis represents effort put forth (investment, both in dollars, time, exertion)
At first, all the low hanging fruit is all cherry picked, you advance quickly up the performance axis in an efficient manner. Each Audio/HT endeavor, you pick what you feel is the the sweet spot, execute to that point, and move on. For each enthusiast it's different, but there's a point on that curve whereby it's still advancing upwardly in performance attained, yet one begins encountering the inevitable diminishing returns and excess effort/$,...thus they stop there.
Some are more inclined to pursue their specific area of interest. Those inclined to read technical info, ...acoustic threads/forums etc,. We view this differently,..this is our area of concern. I love a great image, but I don't read any of the video threads unless I need very particular information. For my modest, near-field space, an Oppo95, and a new Panny 65" plasma is fine. Now dragon and local, they may not be interested in resolving the infra-bass down to 5hz,...as I am. For them, C+ is good enough wrt infra-sonic resolution at realistic levels. Perhaps they picked an adequate point on the log scale, jumped in and executed at that level, ...and moved on to elements that interest them further.
Many savvy enthusiasts realize the big gains,..the huge jumps in real performance are not found in exotic cabling. They are not gleaned from chasing the latest power protection scheme, line cord, or any of the various feel good snake oil approaches. The big gains in performance are firmly entrenched in loudspeakers, and optimizing their acoustic interaction in room. I think it's clear to all here, that ETC plays a role in that effort.
Similar to sdurani, my question is, where does a properly fleshed out ETC effort fall in the log scale mentioned above?
