tony1954, I think you are correct for a certain percentage of people. Which is probably small.
My (limited) experience has been otherwise. A few times to my amazement. I have had people who like music listen to songs that THEY LIKE on my system who come away utterly unimpressed. My wife being one of them. They are even less impressed when they find out what such a system costs and when they consider how it would affect the decor of their home (my speakers are 4 feet tall, weigh 140 pounds each and a black......my wife hates them).
So yes, I agree. Folks have to hear good sound to appreciate it. But once that appreciation develops they also need a way to do something about it. If you tell them it will cost as much as their mini-van, BMW......or hot rod snowmobile..... it becomes a harder sell.
Anyway, I've been down at the cabin listening to my $500 system and it is all too clear that it is not a $20,000 system. But it is also clear that it sounds good enough to enjoy even from an audiophile standpoint, even for periods of serious listening.
I should also clarify something. I'm comparing it to my home system which was probably around $20k new. The system at the cabin would probably have cost around $1200 new. A quick eBay search shows my home system's basic components could be purchased used for about $6000, closer to $7000 with similar cables.
