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?

You are also forgetting a point. If the company uses the best upgrades for its 2.000$ amp than how is he going to sell his 5.000$ or 20.000$ reference amps. 5.000$ amp should sound clearly better than 2000$ amp in to justify its additional cost. So they need to produce clear-cut sound difference levels between their 2.000$ - 5.000$ - 10.000$ -20.000$ models. They know that today a very wisely upgraded 2000$ amp can sound like a stock 10.000$ amp easily if not better.
