I think Mceljo is correct. I like the idea of looking and finding the best VALUES. I've tried cable which costs about as much as a small car and have had better results with much less expensive wires. That's just one example.
The often astronomical cost of high-end components can be rationalized and justified in many ways. After being even a small player in this game for many years, I'm convinced that past a point, as audiophiles pursue "accelerating returns" it's really about "STUFF". It is no longer about the music. So often, today's great stuff is tomorrow's trade-in.
There are no "laws" involved. if you spend x amount on a system and it sounds good, and then you spend x+ to "improve it" what law is at work besides the law of thinner wallets? It's seems ludicrous to me to try to mathematically quantify the level of improvement and somehow correlate it to the amount of money spend.
I suppose in theory, if you're system is "99%" there, and you get another .5% maybe you'd think that was a substantially accelerated ROI. :) Yeah, maybe.
I think a valid comparison can be made with high-performance car engines, something I know more than a little about. X amount of dough will yield X horsepower. To get maybe 5% more HP (no not THAT HP!) will cost exponentially more than one's initial investment. Is it worth it??? I guess a lot of that depends on how deep your pockets are.
Please, no snarky comments using the word "accelerating!" :)
Robert Harley seems like a very nice man but he does have a magazine to run. The never-ending quest for the "Absolute Sound" can help the economy but it can also make you crazy.
It's been said many times before, but think about how many concert tickets or disks a person could buy if he/she didn't buy that bazillion dollar next component.
