The Law of Diminishing Digital Returns

Hi Jaybo,
It wasn't my intention to suggest that digital is superior to anologue or even to broach the subject. I was trying to address the difficulty some people have trying to justify the proportionally high cost of sliding up a few points on one of those dubious "pecententage improvement" scales.

Early on, Hollywood identified a quality, some actors possessed, that seperated them from the many other talented actors who were more than capable of meeting the demands of a script. They simply called this quality "it".

As a measureable percentage, what does Clint Eastwood bring to a film that another competent actor cannot if truth to the script is used as the measure. Now, we all understand why an actor like Eastwood demands a much higher fee than other actors who could skillfully play the part; so if we can equate that script to an lp/cd, then we can understand that we are not really paying a lot more for a few percentage points but rather the emotional involvement associated with those points.

Mattcone- I hope I'm addressing the meat of the issue you had in mind.

What are "tin ears" missing?

In the early days of CD, expensive high order analog filters were necessary. Nowadays, oversampling allows for very simple and cheap analog filters to do the job.

In practive this means that even the cheapest DAC's have THD + Noise of less than 0.002%. An expensive high quality pro studio grade 24 bit DAC might get you down to THD + Noise of less than 0.0007% (roughly one third less noise and distortion).

Since high-end speakers typically have a THD of 0.3% at best, an improvment in the third decimal place on a DAC seems rather fruitless.

All DAC's, even cheap ones, have distortion numbers that are hundreds of times less than compared to a speaker or to what people can typically detect in blind tests. Perhaps they only test people with "tin ears".

For those who seek audible improvement from the third decimal place of one percent of distortion and noise, my hat is off to you; you must have amazing hearing! Do you find even the very best speakers disappointing?

Shadorne,
Mabe, mabe not; it depends. The individual components of an audio system are like the tools of a painter; it takes more than brushes, paints and canvas to make a masterpiece;
it takes an artest. And, it's not about tin or golden ears. Considering the amount of time I once spent cranking "Dark side of the moon" into my headphones, I seriously doubt my hearing is what it once was.

I tried twice, with analogies, to demonstrate that art can't be measured. I regret that my efforts came up short. I can think of a third analogy concerning one's search for a soul mate, but that would get me into way too much trouble. Good listening.
