I believe todays receivers, pre/pros with power amps, and integrated amps do indeed pretty much deliver similar impressions with any given speakers. This has been my annotation of it from what I've heard. What I perceive to be different is quality related to the life expectance of the product. I see offerings on ebay for vintage components, which, as listed, state the components, some made in the early 1970's, are still functioning. Referencing these components to todays components I wonder if the products offered today will still be working 20 or 30 years from now. I don't think they will since younger folks seem to be driven by a function to price ratio. They seem to be drawn to a product that does the most for the least money. Hey, isn't everybody drawn to this; but, younger folks don't seem to realize to get the most for the least expense means build quality and serviceability suffers.
