usb cables?

Then you need a Memory Player.

It is much easier these days to acquire gear at reasonable cost, which if hooked up without thought gets a lot right

 

 

but maybe this is better still:

And no USB.

I was thinking of that (seriously). But not useful here.

But might we need something to slam at ...

 

I wondered how much sheer experience would bring to the table. Nothing to discuss for math or EE design or anything, but still, in the end it can even be brought down to that. For fun:

 

I always thought that opamps "sounding" was bull. Especially when I learned their characteristics, I knew it was BS. They just work at some speed, have some feedback, should not oscillate, be stable. Once that is met, what can go wrong. No, what can sound different (now ask Marce).

Well, ALL. A devastating all.

 

Then, working on this through the years, at least I am so that I want to know what the heck can go "wrong" for sound with these nasty little beasts. And from there you learn the characteristic behind the characteristic. Nothing for datasheets, but all combined data points and how they work out. Btw, nothing measurable either.

 

This is not really about golden ears, but it is about experience which consumes a lot of time. And this is one small aspect only.

We were talking about cables ? same thing. Without the vast experience I wouldn't hear a difference (U suppose). But with, and especially with the knowledge of what's applied and especially why that is applied, it is heard without a single doubt.

So I know what I did to the Lush. An explicit job which worked out as intended. I could only do that by first making the Clairixa, which (saying again) is that "best to spec" USB cable. Took 6 months (laugh) to get it there. Did it work out ? yes. Well, we (a few 100) thought so. Until again experience told it sounded the best digital ever. Not good.

 

So see, from there you can make it go the opposite way. It really worked (not to you 4 because you don't even attempt). But mere point: yes, you need those ears of experience - and especially an absolute "auditory" memory - to not mess up and end up with something which is subjective to your ears.

Not golden ears. I think that is something different. If I were 85 wearing hearing aids, I suppose I would still to better than today. Just more experience than today.

 

I will give you more argument for slamming:

This whole world of audio is one large virtual world. All what happens in there can not be measured (at least not by me and my gear) and thus can only be reasoned. If something needs more slam, it needs to be fed with more slam. In our world this is usually current (but not necessarily so). How to gee it there (where ? that's task #1). Is slam more bass ? is it in reality something else ? is it perhaps taking out highs ? an other frequency ?

That's the ears of experience. The application following is real. You could make it. Marce could make it. But the why comes first. Reject all of that and you're not an audiophile to begin with. A good EE undoubtedly.

 

I have said it quite some times before: the both don't go along well. An EE shouldn't try to be an audiophile because inherently he can't. But an audiophile can start to be an EE ...

 

The most challenging part is the explanation of things which can't be explained - not by today's knowledge and laws. First listen with whatever ears, and next reason whether it could be possible at all. You can't ? then it can't exist.

It is a bit problematic that not everybody can reason the same. This is related to base knowledge and also to the ability to "reason". Next up is making something out of it, which also is not for everybody.

 

Lastly, a best argument for slamming:

So Yes, the Lush was created to sound as it did when it was finished (that maybe took a month, which was mostly consumed by waiting for purchased parts, each day). The Lush^2, however, was created because people asked. I just did it. There was not listening involved (by me). Only buying some parts again and go for it. I did not care much. People asked and at the 3rd I could not say no. This was a year ago.

Up to this G-D date I am reasoning how the F cable can work as it does. I assume I will get there, but not so yet. It really does not need any ears to hear its working (you can feel it in the stomach already). But I need to know why because if you'd ask me, I have no real answer. A lot of blahblahblah, yes (I referred to myself yesterday).

 

Now aim.

Not even to the N.S.  team who designed the LM4562(LME49720) series of opamps

 

I am not familiar with particularly those, but read the datasheets of them. They can't be measured by normal means. It first needs attenuation and some more tricks and multiplication to "find out" the THD.

Still, people in here think that what we can hear, should be measurable. Well, I agree. Now the how-to.

[PeterSt]

No Frank ...

[PeterSt]

Still No.

[PeterSt]

Yes, so sad. And that while I warned for you guys.

Back with the pathetic digs...

 

What else would you expect when you say this yourself as a response to a subject which is 100% about noise, to next claim it won't matter while it is so so easy to prove that it all matters.

You also could try to respond differently for once.

 

So you start this yourself. Not me. Not Alex.

[PeterSt]

I will give you a good laugh: my side hobby is not noise. It is my job, in audio. And so easy to prove / show (did that a 100 times already).

[PeterSt]

 

Can I help ?

Ah, the old "audio is special" argument.

 

Audio *is* special. Small example: would a bit of jitter be irrelevant in telecommunications, with audio the same amount will be audible. I don't say I could qualify it (audibly) but a difference in somewhat higher and lower jitter (without quantification) is easily audible.

 

From here on, audio is special from most angles. The only bad thing is that people tend to come up with what they hear. They can't measure. And about the latter, you can't either;

It wasn't quite proper. Lots of things were not controlled. The outcome was surprising enough that I'd like to see it repeated. I'd also like to deploy some more sophisticated measurement gear than was available on the occasion. Neither is likely to ever happen.

 

 

Maybe you recall that in that thread of concern (blue/red pill) I warned a dozen times in advance about what you wanted to measure, couldn't. I am not sure whether this question got deleted by the cleanup Chris applied or that I never got around posting it, but here it is again: what would you bring these days ?

This is not a cynical or sth question. I only claim that

a. things are clearly audible

b. which can't be measured.

 

And remember, in advance of that pill happening, you thought differently. E.g. Marce will do too (I don't want to put words to his mouth, but I am pretty sure he will).

 

Btw, indeed back at the time it was not about USB cables at all. So not sure whether by now we can generalise things.

What would you bring that you possess for real ?

Frank, cables can't make a difference whatsoever. Don't you know ?

 In these days of tight discretionary household budgets, I doubt that you get too many customers requesting a refund after purchasing your Lush cables !

 

Alex, 100%. Really 100%. But I keep on pushing.
