If good sound is not an issue, you will get nothing! Many of these posts or claims are just silly.
The consensus seems to be "Anyone who spent more money than me is just trying to gratify their ego."
My system retails for more than I care to think about (I of course, did not spend that much on it.) but I have never regretted a purchase based on the slim margin of improvement.
I am happy with how my system sounds now. Timbre's are more correct the sound stage is bigger, deeper, and more defined. All of these attributes come at a cost. Did I spend too much? Some might say no, a starving man in a Chinese prison for owning a bible might be speechless at the idea that it is possible to spend that kind of money. Who's right?
I had $6000 speaker for a long time and I was very happy with them. I sold them recently to replace them with a $16,000 speaker. The differnce is not marginal or subtle. Ultimately they do the same thing that my very first stereo (bought from Readers Digest around 1976) did. They play back the signal sent to them. The RD system sounded better than my transistor radio. It seems many think I should have stopped there.
At what point have others determined that I need to be satisfied? How good should my system sound?
No system is ever going to sound like live music. Live music is an absurd standard by which to judge a system! Musical satisfaction has more to do with the imagination than the stereo! Determine to enjoy what you have, and you will enjoy it, but don't make silly statements about diminishing returns to condemn what someone else has determined is justifiable.
