09-28-12: MapmanThanks very much, Mapman. Your assumption is correct -- I have never had an affiliation with anyone or any organization in the audio industry. Nor with any consumer product, for that matter. My background is in defense electronics.
Al has deep technical knowledge in areas that are well documented and communicates clearly and consistently in a manner that I seem to understand. Also Al is not a vendor TTBOMK.
Regarding various statements that have been made by others to the effect that opinions about tweaks are invalid unless the particular tweaks have been tried: While opinions can and will legitimately differ, and widely, about where to draw the line, I would submit that there must be SOME finite limit to the degree of apparent absurdity of a tweak, beyond which it can be rejected a priori.
IMO, a lot of the tweaks that have been mentioned and/or linked to in this thread, especially in the recent parts of the thread, exceed any such limits that are conceivably within reason. And, frankly, I doubt that anything constructive can result from discussion of them, which is why I haven't posted in this thread in recent days.
Regards,
-- Al
