"The Law of Diminishing Returns"???

Instead of expounding on what's been said, which I believe all have their merits, let me just give you another example of what can work together.

I have a $9k amp and a $150.00 passive. Yes, those are the NIB prices. I'm on a preamp quest but haven't found anything yet that knocks my socks off, so I continue to use the little passive.

It really is all about synergy.

Forget the pricing. As Driver says, it is all about synergy - between your components as well as between your stereo and your ears. The ones hung up on cost can have it. Experimenting will yield far greater results than going by pricing hierarchy. Arthur

I do believe that synergy is very important in audio equipment and it is not all about price, however I think the original poster is trying to find out that once you get over $1,000 are the improvements very very small? And the answer is no.

There is some truth to what you claim. Certianly, the cosmetics seems to be a big factor when the price is above $2K or $3K when it comes to amps. This is why I concentrate on Parasound, Plinius etc.., because they are a good value at their price-points and the manufacturer has not put exhorbitant monies into cosmetics. The guts is what counts in my book.

Your right, synergy is important but I really think our rooms are the most important thing of all........I think that room treatment and Isolation devises will get you more for your money than just getting better components alone.....Do you agree or not?........Richard
