What's the difference between a $50,000 home stereo system and a $1,500 one you can buy at Best Buy?

That is a rather broad question, especially since you have said specific brands you are comparing. I am sure there are many differences in quality if there really is that big a gap in price points.

It would be hard to get a normal system above $10,000 even with top components. On the other hand, if you start wiring up a whole house with multiple listening areas and in-wall wiring that could add up in a hurry.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
