Agreeing with you, I turn to "unproven/no patents", natural herbal supplements that lack the proven side-affects of patent drugs because of what you suggest in your above. But on the other hand, we're talking life and death as opposed to 50/50 choice in which Amp is mine. A subject I have spent time learning about, in the case of patent drugs, these drugs are developed over many years and then moved into human based clinical trials, based on FDA reviewed requirements. The outcome, being compared to placebo based control groups. As an example, without the drug, there's a ten percent chance you'll live or a ninety percent chance you're toast within a year. With a particular patent drug, your chances are improved to thirty percent and your chances of becoming toast have been reduced twenty percent. That's statistically significant. Which do you want, a one in ten chance of survival as you're always welcome to tell the medical practitioner to keep their prescription. Or you can hand the doctor a pen and say you like a one in three chance of survival better then the alternative.
Now on the other hand, when it comes to amplifiers, guessing is not proof of a product being better and if for the price, like flipping a penny, if the best one can do is 50/50 for an amplifier that's suppose to have a clear and noticeable difference, I'm not convinced admission to the party is worth the price; hence the ninety percent requirement. If it's a stated clear and noticeable difference, then it's a clear and noticeable difference one should be expecting, so ninety percent is not an unreasonable expectation. In the case of patent drugs, all that's being said is your chances of improvement have been improved and we all hang our faith on the hook known as the FDA and hope this is not a product that's been diluted by a crooked pharmacist or manufactured in a contaminated product manufacturing lab.
The point, comparing life saving patent drugs the FDA regulates the development of to that of the unregulated results of double-blind amplifier tests, is not a valid comparison; hence why you won't see published, peer reviewed documentation supporting claims of the superiority of one amplifier over that of another.
Not everything in the world has to be fully justified for cost effectiveness or best bang for the buck. Do you buy a car just powerful or spacious enough to get you from A to B, or eat food with just enough calories to keep you going or live in a house with just enough floor space for the number of occupants or wear the minimum of clothes just enough to keep you warm? Some people like to buy far more than they need, or high-end or luxury items whatever. People have different values.
Pretty much, in your above, you've just described my life.
And I agree, people are welcome to spend/buy anything they want and good for them. As an example, if John Travolta wants to park a jetliner in his front yard and it's code compliant, more power to him.
The line is crossed when someone makes claims that are not true and double-blind tests consistently show that once the curtain goes down, so does the accuracy of choice. The point, I haven't a wit of trouble with someone who wants to spend a $100k on their enviable system. What I have trouble with is someone saying their amplifier creates clear and concise sound quality improvements, to the point that they'd have no trouble picking their amplifier out of a mix of less expensive amplifiers when in fact, once the curtain goes down, immediately, so does the accuracy of their claim.
Note that amplifier manufactures don't publish information claiming their amplifiers are superior to others and note how their wording is clearly guarded commentary so as to prevent lawsuits surrounding false claims. Here's a link to Classe Audio,
note how not a word of the superiority of their product over anybody else. Not picking on Classe when I post, all they say is, buy Classe, we have engineers fluent in analogue and digital design, we use quality parts and we're about performance. None of which is any different than what can be said about a hundred other amplifier manufactures.
