After perusing some of these threads, I feel I must weigh in on a couple of issues.
First, people seem quick to put DUP on the ignore list. While his shrillness is such that I think my dog can hear it when I read his posts, and his run-on sentences and grammar could use a refresher lesson from his grade 10 English teacher, he does bring up some worthy points.
Sifting through his posts, he has provided some links which (for me at least) have provided food for thought.
Second, another thing I notice is some of the posters like to question credentials of other posters. Please stop that. The ole "You can't post that because you don't have a masters at blah-blah U" just serves to reinforce the perception that this forum is full of "audiophile snobs". One may wish to perform some navel-gazing before lobbing this criticism.
I'm of the school that "if it can't be measured, it can't be heard". A poster who tries to find an objective answer to his (or other posters') subjective findings is the one who receives my kudos. It is too often I am seeing people stubbornly clinging to the "these amps go to eleven" mantra to defend what their ears (allegedly) detect.
Companies like Monster Cable at one end, and Audioquest at the other do this industry a disservice. Dismissing decades of peer-reviewed papers by the AES,IEEE, et al are meant only to serve the bottom line on their quarterly profit and loss statements.
I'm not an engineer, though I have a technical background as an electronics technologist. I have, on occasion, gone to the nearest univ library to investigate various journals on some of these subjects.
I believe most of us have the same goal: Audio nirvana. We are a small and esoteric group though, deeply submerged in a sea of nasty 128kb/s mp3's and distressingly over-compressed cd's (loudness wars). I suggest we divert our energies to these issues in the hope of leading the industry as whole down the path of audio enlightenment.
As an aside, if people find DUP shrill, maybe he needs to be heard through the latest Audioqest DBS cables or even through The Glob
