Peter, mtemur,
I do not understand why you guys can't process that not everybody wants to be an audiophile hobbyist, auditioning extensively at dealers and learning about all sorts of components, and what sounds like what, and what causes what to sound like what, and learning about system matching, etc., etc., and going down all of our various rabbit holes.
Some regular people just want to listen to music by buying a modest but nice-sounding stereo with some advice and some educated guesses thrown in.
If my friend read all of the posts on this thread and researched the pointers in all of these different directions and responded to all of your questions I am quite sure he would throw up his hands and say: "Thanks but no thanks, I'll just keep what I have."
