Exactly what are you referring to?  What design or engineering features are evidence of that?  Please exclude any reference to those constraints imposed by the price.

I think this is somewhat like asking the difference between a Volkswagen and a Porsche (name your sports car. It sounds many times better.

I think there is a difference but not sure if 50K difference.

Engineering and materials mostly. 50K may be a lot to the average person but perhaps for some it's not that much. If the expensive loudspeaker is not in your budget, does it really matter?

Consider yourself blessed if you honestly ask yourself that question…
