The Flat Earth Society... I know several members... It's those individuals, who are generally quite intelligent as well as opinionated, but who REFUSE to accept or EVEN TRY something since it does not make sense to them or they cannot calculate or measure it... They are "close-minded and definitely not "open-minded"...
Some quotes that I have heard from Flat Earth Society members;
- Wire and Cabling in a hi-fi system makes zero difference at all, especially power cables... How can it???
- Tube-based systems are full of distortion, sound warm and coloured.
- Solid-state systems are dry & analytical.
- Class D amplifiers have a long way to go sonic-wise and cannot compete with Class A designs
- Digital Reproduction is more accurate and sounds better than Analogue (Vinyl)
- Analogue Reproduction is more life-like and sounds better than Digital (CD's)
I could go on & on... The one thing I've learned over many years is that EVERYTHING makes a difference. "Everything" could mean different platings, different metallurgy, different geometries, different components (resistors, capacitors, tubes, dielectrics), different cables, different shielding techniques, cryogenics, "burn-in", etc.
Are theses differences subtle? Sometimes YES and sometimes NO... Are these differences an improvement in sound quality? Sometimes YES and sometimes NO...
It's the wonderful world of Audio... Enjoy the hobby!

Well said. There will always be (always have been) those that are so closed minded that they can't appreciate difference: opinions; realities; anything that challenges their dogma. For those of us that do not really understand the word:
dogma
noun dog·ma \ˈdȯg-mə, ˈdäg-\
: a belief or set of beliefs that is accepted by the members of a group without being questioned or doubted
I'm just not cut that way. Call it scientific curiosity. The only things that I accept without question are physical laws. Imagine what would happen if someone threw the gravity switch!

OTOH there are those who are so open minded that there brains have fallen out. It is times like this that lead me to believe that I must be one of them to keep this up.
sigh... Everyone take a deep breath and don't make this into what it isn't.
Back to the topic, but first, EVERYONE read this sticky:
http://www.audiocircle.com/index.php?topic=112461.msg1167359#msg1167359Especially this: "The rules in these discussions are simple: use the same attitudes and words that you would use in a face to face discussion with someone that you respect and that you know respects you. If things get off the track, I will be watching as closely as time permits and will apply all of the Rules of Audio Circle as even handedly as possible. I am human and I expect all of you to keep me in line if need be. PM's will be used for arbitration as is the norm here at AC. Bottom line is that I expect these discussions to be self-policed by well intentioned, intelligent participants. If that is not you, then best not join into the dicussions"
I understand now that the 'Theater of the Absurd' that was intended by a self-deprecating inference to my membership in the the FES is just flat lost on some. Been there. Done that as a recovering unwavering objectivist. Wars have been fought over the lack of a sense of humor or self awareness.

A sense of humor goes a loooooong way in civility among equals.
Pete, I loved the irony of A vs. D and D vs. A. I know one guy that has vacillated between those two positions for years. Can't seem to make his "ears" up. I believed it myself for about two weeks back in the 80's right after CDs came out. No noise, and sharply defined. It took a while for me to get the reality: digital over a 14 bit player was just wrong. I have come to appreciate the strengths and weaknesses of both formats as I have gotten older.
I held the position that wire is just wire until I was compelled to
disprove a guy on the old Madison BB (back in the days of 2400 baud) and started listening to lengths of copper wire of the same gauge. That is when I discovered dielectric constants and dissipation factors of different insulators. Surprised was I! Me, wrong? Oh, yeah: wrong.
Now I can predict the change in R after cryo of 500' of wire within a few ohms. Yep: measured it many times with 8-1/2 digit Keithley meters when I worked in the semi industry. It was awesome to have access to gear that I could never justify when a lesser device works in the real world of day to day electronics.
Guitar guys have known the differences between caps for fifty or more years. Build matched circuits of a 5E3 Deluxe using matched values of orange drops vs astrons vs mustards and there are 3 different sounding amps. Measure different, too.
Like you, I know that everything makes a difference. Sometimes they are very small, sometimes large, sometimes for the better, sometimes for the worse. It would be the same as saying that all humans are the same. It is obvious from this topic that just ain't so wouldn't you say?
