Just wondering...

Great post, bigkidz. Best wishes for success in your business.

"  Every established business wants to live on foolish and rich and will apply all possible and impossible tricks to convince."

If you actually believe that, I really don't see how we could have any meaningful conversation. That's a pretty extreme statement, and being a business owner myself, I know that I don't fit your description. You may not believe it, but it is possible for a survive by treating customers right and not playing tricks. 

" I'm not rich, but wealthy and the reason why I am is because I do math the following way: How not to spend much on automobile maintenance, how not to spend much on energy, gas, healthy meals, comfortable quality apparel and certainly home and pro audio! Believe me my profession IS finding right numbers just about for anything around me. I breath with numbers, figure out mind behind each word written or spoken WITH numbers."

I have no doubt that you are very good at whatever you do for a living, numbers or otherwise. But that doesn't mean you can see things better than anyone else. I'm an MBA. I know several people here are engineers. We have some equipment manufacturers as well. And the list goes on.

Anyway, you didn't get the point of my last post. I understand that you are capable of eating healthy, fixing your cars or whatever. I believe you, and don't doubt a word of it. I was trying to say something else. If, for example, you called a company that makes dac's and asked them how much they pay for things like chips, or any other parts that go into the making a product, they won't tell you. And if they do give you a number, 99% chance they're lying. That's just the way it has to be in business. And as a result, you'll never know what they pay for the parts that go into their machines. 

maybe "nobody" does blind listening tests, because "nobody" doesn't understand science

I know quite a few consumers who do them and many manf.s who do

" maybe "nobody" does blind listening tests, because "nobody" doesn't understand science"

Or maybe DBT's aren't necessary to select components and listen to music. 

"I know quite a few consumers who do them and many manf.s who do"

Like I said in my last post, I have yet to see anyone use DBT's in any meaningful way. Your post just reinforces what I'm talking about. You claim to know the science behind all of this, but you can't provide any real info or examples to support your position. Knowing a few people just doesn't cut it. You seem to have an ax to grind here. Maybe you're unhappy because your system is lacking. Why don't you list all of your components and let us help you out. 

I loved the story of the loaned CD player where the friend couldn’t hear the difference, but the owner could.

I think that’s what often involved with tests to see whether or not high res makes a difference. (Of course it could be the system itself that masks the benefits).

Its not the audiophile’s ears that are better, but our brains that have developed to hear and appreciate the subtle nuances that better playback brings.

After an upgrade I sometimes feel like my brain is not developed enough to fully appreciate the benefit of the upgrade/tweek. In time I can hear the benefits with greater contrast.

Recently when switching on/ off my subs for a friend, they thought it was a subtle difference. To my ear it was large and the full bandwidth (only coming in at about 35hz and a steep slope) sounded much more like a musician in the room.

I'm soon going to augment my Ethernet cable for an optical Ethernet isolation section.  I have a feeling the more relaxed nature of the optical (due to isolation from the computers power supply) will reap large benefits that the casual listener would regard as difficult to hear, or subtle at best.
