Completely agree ...

Completely disagree. In my experience, there is a first level of refinement which allows "high quality" source to sound top notch; followed by the next level of refinement which enables extremely "difficult" material to come to life. The end goal is that there is no material which can't be reproduced sufficiently accurately to make it a completely engaging, enjoyable musical experience. That first level of refinement I've heard many times, and it frequently sounds disasterous with "poor" material -- completely unnecessary for that to be the case. The headache in the whole matter is that one has to go to what many would consider excessive measures, have to consider aspects which many would consider bizarre, to get the higher level of refinement to eventuate, to emerge, and most unfortunately of all, it is also a mighty fragile animal! In my experience. But, it is so, so satisfying to achieve ...

The 'game of audio' has several levels: There is the convenience level, with digital mp-3 today, so that you can have your 'music' everywhere you want. In older days, is was the Sony Walkman, and before that, the portable radio, going back to 1923.
The second level might be mid fi, like your kitchen radio, bedroom playback system, or automobile radio. Also, included in the mid fi catagory is most home theatre and living room playback systems.
Then there is hi end, starting with your old Marantz and McIntosh tube amps and preamps, early Audio Research tube equipment, early Levinson solid state, and now a number of relatively expensive solid state and tube products, in ruthless competition with each other to make the best sound possible. Is it worth it? Of course it is, IF you can afford it, or love it dearly enough. Most won't 'pay the price' so they get something somewhat cheaper and more compromised. Nothing wrong with that, as I drive an older Acura, and am happy enough, instead of a BMW or Mercedes, which my wealthier friends own. However, I do not energetically insist that my Acura is just as good as a much more expensive vehicle, in every way.
It is ALWAYS refreshing for me to have a serious conversation with a true audiophile, who is willing to make the personal compromises, to have near perfection in audio reproduction. I learn more from them than anyone else.

Yesterday, I had a satisfying conversation with a fellow engineer. One who thinks like I do about hi end audio. This engineer earns no more money than I do, which is less than it should be to provide a middle class family with what they need, but who has the same passion for high quality audio.
From this source, I learned what 'reference' Blue Ray releases now exist, as well as a number of technical details on the LIMITATIONS of specific IC's, based on both measurement and listening. I, in turn, was able to help this person with their problems and challenges, as well. All told, a satisfying conversation. Could we not have more conversations here on this thread? '-)

Current HD TV is 2.1 Mega pixels and the new Super HD is about 8.3 MP. When people see this they want it and it is coming. The bit rates are of course much higher for this and maybe the audio will also improve or we can hope. I guess our visually senses are easier to sell to.

John, in my audio travels to date I have come across very, very few people who believe in superlative sound: none in person, only a handful in the online world. In fact, there is quite a vehement backlash to this idea by many, if not most people, which I find very curious. It seems to come down to the human condition - if something is not commonly accepted, generally agreed upon, then it is considered by most to not have much validity ...

The analogy with video is easy: better resolution means that the screen can be bigger with no apparent loss of visual quality and is obviously more impressive. In sound, this translates to higher SPL but most systems, no matter how expensive, start to fall apart when pushed - they just begin to sound LOUD, not more intense or engaging. Equivalent to those terrible projection screen TVs you got in clubs and such years ago - yes, they were big but the picture quality was pretty nauseating ...

Fas42, I don't really care what most people think. Out of the billions of people in the world, there are enough people who DO care about audio quality to make it viable. It may be true that the average 'middle class family' has moved away from listening only to hi fi, there as still those who go to hi fi shows, buy quality audio equipment, and come up to me and tell me how they appreciate my products or something similar, on their own.
It may be like the character that we used to hear about, who would play his jazz 78's in his den, hoping his kids will pay attention sometime, yet it is still worthwhile.

It's certainly worthwhile trying to pass the ideas on. A relatively recently made friend who has a highly capable technician's approach to electronics had a quite reasonable setup at the beginning when I first met him, and over the years I've been steadily indoctrinating him into the philosophy of "everything matters, everything matters"; now he's as obsessive about the "silly" things as myself, and achieves quite startling good sound a lot of the time.

Heavens above, he has even bought into the idea of "there's no such thing as a bad recording". Vinyl and CD that were written off as unrescuable when first acquired, are now regularly trotted out to demonstrate progress made ...

I once opened up an SACD player with 5.1 output and regular stereo outputs. The stereo outputs used minimum quality opamps while the 5.1 outputs used premium/better high performance opamps. Whats that all about?

I measured a early Sony SACD player with Nichicon Gold Muse DC blocking caps in the R,L ch and "lessor" Nichcon in the center, suround ch - the Gold caps had more, higher distortion components visible on the LF slope

That's weird, the green non-polar are what Nichicon recommends for coupling apps too, not the gold.
