Placebo is just so incredibly powerful people do not understand it.
This applies to DIYers as well. That is why many of them are so strong in their belief that their "creations" sound identical to gear 100X’s their cost.
Now, funtrollfun, you DO realize that you are on a forum on a used audio website, don’t you? How large of a target audience do you think you are speaking to here? You know, the type who would actually pay $30K for a $30K amp? My guess would be 0% of your target audience dallies in a simple forum on a web page designed for used audio gear.
The fellas that really find your gears, don’t waste their time here. They are busy buying $500K+ cars, $5M+ boats, $5k+ watches, etc. To them, $100K is like $10 to you or I.
Most of us here might spend more money in this hobby than you, but lose very little money making shrewd investments. Over the last 30 years, yes, even pre-dating Audiogon, I have lost money in this hobby, because I change gear frequently so that I may experience much of this hobby personally. However, the amount of money I have lost would probably shock you, maybe 5-10% tops, mostly lost on ads, shipping, and PayPal. I even make money on some re-sales occasionally.
So while you are busy building stuff that you are working on convincing yourself is just as good as the "real thing", I am busy auditioning many different versions of the "real thing".
When the dust settles, at the end of the day, I have a finished product that I can sell if I choose to, you do not. Yes, there are the very rare DIYers that do sell their creations, just as there are buyers of used gear that consistently make money on their gear flips. These breeds are in the very, very small minority though.
In the end, most folks are frugal with their money, it’s just a difference of whether they would choose to spend their time looking for wise investments or building something themselves. It takes all types to make the world go round, not everyone is cut out to be a mechanic, just as not everyone is cut out to be a knowledgeable investor.
In the end, life is short, find what brings you the most happiness, and pursue it. If building your own toys tickles your fancy, have at it. However, stop trying to be so mule-headed as to think that your path to happiness is the way for everyone. There is no one single path to audio nirvana, most here are mature enough to understand that. Perhaps you can DIY some common sense and understanding into your world.
