When does the law diminishing returns kick in?


As I go through these threads reading responses I will look at the systems from answer writers. Wow, some of you guys don't mess around. As a music lover and audio guy myself (since the late 60s) I can't help but be envious.
Although my system is modest, especially compared to some, I get a lot of enjoyment listening to music on it. It took a while and a lot of trial and error to get what seems right to me. But when looking at the super systems here it makes me wonder what I'm missing. With the exception of deeper bass, am I missing all that much? How much would I have to spend to hear real (worthwhile) improvement?

Rule of doubling!

My opinion is that a quantum leap in fidelity will result when you double the price (MSRP) of a piece of gear. As you can see, this is a geometric progression, and not a linear one ($500 to $1000 to 2000 to $4000 to $8000, etc.) Many people will run into "financial clipping" rather quickly!

This is by no means an absolute truth, but rather a crude rule of thumb. A product with a high value to price ratio (Maggie 1.6 speakers) will be a pretty tough challenge to my doubling rule. Of course, synergistic component matching within your system is critical. There are many different types of tonal signatures that various design philosophies of gear will impart upon the music. This is especially true of speakers. AUDIO REPRODUCTION IS NOT AN ABSOLUTE SCIENCE! I view it as more of a combination of science, art, and just plain luck. The music that you like, and the kind of reproduction that appeals to your own preferences is the important factor. It was interesting to note the responses on the thread "Best and worst rooms at the CES". Two different people could walk into a room; one hated it, another loved it. Sometimes, the music being played could influence a listener's opinion as well.

It's ironic that many people ignore a critical component of their system, ROOM ACOUSTICS!!! A megabucks system can sound like crap if the room acoustics and speaker placement are ignored. Also, certain tweaks that cost much less than an equipment upgrade can remarkably improve the fidelity of your system. I liken this to maxing out the performance of a drag racer within a particular bracket, rather than moving up into a higher performance bracket.
I like that advice Reubent. I have owned three different cd players that retailed for twice the cost of the NAD but preferred the NAD. All of them resold on Agon. Soon after discovering Audiogon my wife was wondering what was up with all the UPS deliveries. It definitely adds to the enjoyment of this hobby. Thanks and good luck.
Just a note on NAD; I still have the NAD 3120 Integrated in my second system, driving venerable Totem Sttaf speakers. Lost track of how old the NAD is, over 10 years I think. I kept realizing how enjoyable the music sounded throught this modest system against far more expensive kit, one of the things that led me to downsize.

NAD isn't the only example of high-value gear to consider before spending more, but it's a good one.
p.s. I think FatParrot is onto something with his geometric quantum progression. New laws of economics being discovered here.

Jond's bold identification of $2K as the specific point of diminishing returns, give or take, also accords with my experience across a range of components and manufacturers. Beyond that, its not that you can't hear any difference, but you can pay a lot for modest gains, and wonder whether you are really enjoying music that much more.

There those who needn't balk at $10K or $20K, or $100K per component but they probably wouldn't look at this thread.
Panderso,
It's probably the old hippie/commie in me that balks at spending $10K or $20K for a piece of audio gear. But I admit the world would be a less interesting place to live if everyone were satisfied as simply as me. And what would Hi-Fi reviewers write about?
