Someone please explain the logic of upgrades

I just left a site explaining the improvements that can be achieved with the Audible Illusions preamp (which I happen to own) by upgrading any or all of the following:
- power supply
- signal coupling capacitors
- hookup wire
- potentiometers
- OFC RCA chasis jacks
- signal path resistors
- tubes

Now one of two things is true - either the parts upgrades improve the sound of the component or they don't improve the sound. If the former is true, then I have to ask - why didn't the manufacturer make these same upgrades and produce a class A component in lieu of a class B component? Yes, I know that the cost of the upgraded parts has to be passed on to the consumer, but I bet most of us would readily pay that extra cost to get a tricked out unit. The same applies to power cords and feet. So, why are so many "audiophile" components sold with minimalist cords and feet? If the situation is the latter (better grade parts have no impact on the sound of the unit), then shops that specialize in upgrades are practicing junk science. So what is it?

Sugar, if you believe that, why do you participate here? Perhaps just or sell or buy things? Do you believe that the possible sonic character of, say, coupling capacitors, is audible? Or do you believe that everything that measures the same sounds the same?

I believe that EVERYTHING makes a difference in the sound. Whether you or I or anyone else can HEAR those differences is another question.

As 2 of us have alluded to, all these companies have to SELL components at a profit to stay in business, and the lower the purchase price, the more they sell. If someone else wants a premium version, I hope the manufacturer can and will accommodate them. Doing it this way makes the majority of those sold more affordable.

It's a great hobby, huh!
