And yes, audiophiles do quite a bit of blind testing. Or at least scientist audiophiles do. I was totally blown away when i tested different power supplies, power cords, interconnect cables, and speaker cables on the same system. I basically figured most of the hype was total nonsense. I mean, why the heck would you have to burn in a *cable*? Turns out that you can easily tell the difference in a blind test even though such a test is difficult to arrange - you basically have to have one guy rewiring stuff and one guy blindfolded listening. We were shocked that the differences predicted by the audiophile crowd were mostly pretty damn obvious. I still dont *understand* why some of these differences exist, though others do make some sense.
Actually, I have been messing about with audiophile quality mp3 systems for some time now. I know, I know, it sounds like an oxymoron, but despite popular opinion it is possible to get really impressive sound with high quality variable bit rate mp3s.
It turns out that the secret is in the quality of the sound card you use and the quality of the D to A converter. Using a studio quality soundcard with digital audio output and a nice D to A (I am quite pleased with Theta, but there are other excellent manufacturers) together make high quality variable bit rate mp3s sound quite good on an audiophile quality system.
To give you some idea of how good, I have a very nice transport (CD player for the uninitiated), and direct comparison of CD, SACD, and high quality mp3s reveals only minor flaws. The most significant is that the mp3s sound slightly 'cleaner' than the CD or SACD versions. This is not a good thing for the purist who desires to hear the sound *exactly* as it was recorded, but many less discriminating listeners actually prefer the mp3 versions.
Somewhat off topic, of course, but it is interesting to me that you can indeed build near audiophile quality sound systems based around mp3s. Not something there is much discussion about in audiophile communities as yet, but as digital encoding gets better i suspect more and more audiophiles will cross the 'digital divide' that currently exists. For instance, the same sort of thing happened with the transition from vinyl to CD and SACD- even though some diehard purists still sing the praises of vinyl, most audiophile folks now agree that SACD is the 'best' sound currently available.
Another selling point is that truly digital recordings stored on random access media do not degrade over time, while the CDs and SACDs in your collection do so demonstrably. Interesting stuff.

Blind testing works the same way, except that each cycle involves a random choice between cables A and B.You control for the "thermal characteristics of the AMPLIFIER" by designing the test carefully. No problem.
And, yes, you can hear the difference between cables in blind tests. And it is very easy to do... if the cables are sufficiently different. I went from plugging in my speakers with lamp cord (don't ask) to some whiz-bang audiophile speaker cable and I fell out of my chair.

As for the idea of selling "special" cool-looking plastic parts and claiming they improve the sound... that business already exists, and it's called "Bose". :)
Actually, that's not fair. Audiophiles love making Bose jokes (bitter jealousy, you know) but I believe that Bose has a quality product. The product is composed of (a) a box that audiophiles laugh at, but which can produce better sound then any random boom box, and (b) amazingly great marketing, such that the customers truly believe that they are hearing great sound. And so, therefore, they are.
Audio is psychology, and reproducing audio is as much magic as it is science. I've heard it said that the customers who brought the first hand-cranked record players were amazed by the realistic quality of the sound, and were often unable to tell the difference between a live band and a Victrola in blind tests.

Young people tend to like modern equipment better, older people (30years and older) want tube amplifiers. So why is that? It's because of the things the people grew up with. You are accustomed to the sound of your childhood, and that's the sound that is comfy to you. It has nothing to do with the naturality of the sound or anything else, it's pure conditioning.
I remember an experiment done by the c't magazine, where they tried to find out what compression format sounds better. The only one who was pretty good in finding out if the sound was coming from a compressed source even at higher bit rates was one with a slight ear damage, because he had a different listening curve than the others.
And if you would make an experiment where the sound is played live vs. played from a digitized or an analog source, you will notice a similar thing: The live sound will be the least pleasing to the people who want tube amplifiers. But if you put a low pass filter on the digitized source they won't be able to tell the difference.
If you look at the current electronic music scene, you will find that it has adapted to this already. You can put "analog" filters to make the sound more seventies, you can add "vinyl crack" to improve on that. Basicly the "back to the analog naturality" movement is nothing else than a "back to the limitations of 60ies technology". Eventually it will die out when the people used to those limitations die out.

I like tube amps because I feel that they add a certain imperfection that gives music character. The best way I can describe the difference is to compare a tube amp and a solid state amp with this example.
A tube amp is a concert hall. The seats closer to the stage hear a different sound when compared to people sitting in the back. The sound isn't perfect but you are hearing the music directly from the source.
A solid state amp is a concert hall where you are sitting in the "perfect" seat. The instruments/people blend perfectly. There is no emotion since the blending is perfect. You do not think about the music, you just listen.

You go way too far when you ridicule people who say they hear differences that can't be seen on instruments.
It's just wrong to couch this in terms of "If it's some mystical thing that can't be measured or detected in any way, it's no more than some poor man's religion." Fact is, when someone says they hear a difference, the "thing" IS being detected. The difference IS being measured. It's being detected by the listener's ears. It's being measured on a scale defined by that listener.
The problem is that human ears are not calibrated against any objective standard. In the best cases, they are the finest detectors of subtle differences in sound available to us, far surpassing the sensitivity of the best mikes and racks of measuring equipment. They are also, unfortunately, completely non-standard in their reaction to input, subject to variation depending on a host of external and internal factors, and their results are not repeatable from instrument to instrument. That doesn't mean they are insensitive. That doesn't mean they don't actually hear a difference. It just means that the difference may or may not be obvious to another listener and may or may not be meaningful to anyone except the person listening at that moment.
I have no doubt that if you have good hearing and a love of music, you could listen to a particular orchestra play a particular piece in a particular venue many times over the course of years. That piece could then be recorded by that orchestra in that venue. As a fully-qualified judge, then, you could listen to the recordings through tubes and solid-state, planar and box speakers, etc., and be able to tell not only which ones were different and which you prefer, but which recordings and playback setups are more accurate. Just using your ears. And your results may not track in any meaningful way with the measurements produced by that bench full of instruments.
In that case, I'd consider the conclusions of the qualified listener to be far more authoritative than those of the technician who simply looks at the output of test instruments.

Well, I don't have much of a problem with that. If someone likes that kind of distortion or frequency response, I'm not going to argue against a question of personal taste.
The thing that gets my goat is when it's basically getting into the kind of pseudoscience that you mention: about how solid state isn't accurate enough, or somehow clips the sound although you can't see that on any oscilosc

Up to a point. As a guitarist, I have not yet seen such a device which converts my 100W, sterile, accurate MOSFET amp into a valve amp. As an engineer, I'm sure it's possible, but it's a LOT harder than just messing with EQ. Even the modelling preamps (which seem to be convolving the sound with the FIR response of whatever they're modelling) don't get the ringing clarity a

Sound with odd harmonic distortion sounds harsh to our ears, that is 3f,5f,7f etc.
Valves usually produce even harmonic distortion, transistors usually produce odd harmonic distortion.
