Have you ever noticed differences in "sound" between different materials fulfilling the same functions? Do you find that all OPAs, even high performance, sound the same?

Have you ever noticed that improving the power supply (s) of a DCX2496, for example, and modifying its stages of analog outputs considerably improves its sound quality? And that the changes in sound quality are incomparable to that visible ... to the measurements?

Once again, it would be very pretentious to pretend that we can measure everything and evaluate everything. Thanks God, there is still a bit of art and mystery in the world of audio.
That all sounds a bit hit and miss to me. I've played with EQ, distortion, crossovers, moving my speakers and listening position....does any of that count?
 
The big studios closed down. Recording mostly moved to many smaller project studios. The better of the old recording guys mostly stopped getting calls. Most artists have little to no money and the project studio owners work for cheap. Only Al Schmitt still gets a lot of calls, so the other guys say.

Last time I've checked Steve Albini is alive, kicking, very happy, and doesn't miss the big studios a iota. Neither do his customers, required only to pay for the tapes and his time.

Of course, too, but not only.( It is of course a personal feeling.)

As a painter can work his technique and his drawing, there will always be the character of the colors he uses. A subtle combination of colors, material, and the way they react to his hand and will. Everything has an own character.

You dissed the Topping. What's your reason?

It is probably a bargain. No disagreement on that.

I don't believe it sounds comparable to DAC-3 or to AK4499. It can't, there is no way in hell it could. You can make arrangements to listen to the various dacs we talk about or not. I can't help you with that unless you want to come here. If you want to do that you are certainly welcome.

Steve is special in my book, huge highly successful repertoire but charges a fixed hourly (last I looked low). His interview with Bourdain on the food channel was a hoot, they flashed the cover of Songs About F******. on the screen. I used to play this at my work bench in the lab, though Kerosene is my favorite BB cut. The ultimate statement on life in the Midwest.

I can in no way understand this enthusiasm for vinyl, which has earned us these pages of endless debate.
Especially when I see the partisans of the cold objectivity of the measuring numbers taking part.
Hint this is a hobby site. People should be able to partake of their music any way they want. Yet it galls you so you keep wasting words saying why it makes no sense. We all heard you the first time and we don't care.


It seems to me that there is a great confusion between nostalgic pleasures and an objective analysis of the indisputable superiority of digital, both as regards the preservation of musical works over time as their distribution to the public without deterioration.
Nope. Not amongst the partisans of cold objectivity anyway.


It seems that many people do not enjoy the cruel reproduction of music, as it was produced, with all its faults which are inherent in human nature.
Is it therefore a nostalgia for the vagueness that the analogic introduces, which always leaves a part to the imagination ?
I would honestly give up now as you have missed the point by miles.


On the other hand, I also don't understand the aggressiveness I see towards the approach of people like Markw4.
Would you try and get an improvement in an amplifier you made from 0.001 to 0.0001% THD with no test equipment other than your ears?
 
How come? That's a pretty extraordinary claim.

Its not extraordinary at all if you listen to some really good dacs. If you only listen to cheap dacs, then you can't know what you haven't heard.

Looks like its time to step away from this conversation as it isn't going to resolve anything. As usual there are numbers guys, and a listener. Bye.

Re-read-you. Who is trying to silence the other? Would you have privileges that I would not have ?
Unlike you, and this aggressive response is an example, I am not trying to impose anything on others. I share my personal experiences and do not hold any other authority than that which one agrees to grant me. And who are the "we" you refer to ? Shame on you for this and from where is your authority ?

Objectivity ? Arf ! Objectivity, truth, what a pretentious, and sorry, 'stupid' attitude !

My rhetoric teacher had smiled.

Please, try to find better arguments. I have done this (with, of course measuring instruments).
It never ensure any audible improvement at those points. often useless in my book. So what is the need ?

Try to be honest with yourself, if you can. Look at all the possible measurements of a speaker set. Does that give you a clue how it will sound?

Not all audiophiles are neurotic. However, roughly 1/3 of them are highly neurotic.
When was the poll taken?

The biggest problem that most audiophiles in general have when it comes to judging equipment is that they don't check: If a change to their system makes a noticeable difference in sound they assume it must be better, rather than A/B checking back and forth a few times over a few days. IMHO They could use some training to correct for that failing.
You've surveyed most audiophiles in general?

There is a big difference in sound, you do get something real for the price difference.
Another claim with no supporting evidence.

You ever get out to Northern California? Happy to play a good dac for you, or let you hear for yourself the difference between various dacs that measure well. Bring your D-20 if you want. Man, will you get a wake-up call.
No need to spend time and money traveling to hear DAC differences. Just set up a casual subjective auditioning session and be woken up.

You want to really wake up? Set up a bias controlled objective DACs listening test for yourself listen as long as you want at your convenience, no stress, no pressure to be used as excuse for not being able to hear a difference. Try it.

What about people who haven't got that option, are they screwed?
See above reply.

As usual, your opinion is correct, those whom you disagree with are wrong and therefore it's time to put your head in the sand again, until the memory fades enough, then repeat the shill material for jam's audio business all over again.
 
Alexandrovich found in his SEM experiments excessive wear particles but used only water for the wet play and speculated about the cooling effect that prevents plastic flow as a reason:
The whole ice skating analogy doesn't hold for me. And as I can't see the heating as a problem wonder what really happened there. It is a loose end.


.
In my case I had the same low noise in all three cases, no change whatsoever between the three recordings.
So maybe skating makes the whole equition even more complicated.

I'd forgotten about that. I really need to get some time to experiment with stuff this year. That needs replicating and I do have destructable copies of the same record to play with.
