Hi Acko,

Could you give some more details please

Some questions that come to mind:

- Do they need a bipolar pre-reg as I believe the previous revision did? I think the combo-board versions of these needed bipolar pre-reg didn't it?

- Possibility for a stand-alone 3.3V ultra low noise reg? ie just the one reg on its own rather than the complete kit of all regs required for the AKD12/18.


Cheers,
Chris

Chris, the regs have floating inputs and outputs, you can use a dual positive supply to make a bipolar supply if you wish, just with different input wiring. in fact its a more straight forward connection, since the dual regs (the only ones that require it) are wired that way, you need to switch a bipolar supply around and connect 'ground' to 2 inputs to supply the dual input required.

as to your second Q, I have the same question.

what the hell are you on about Joe? you are the one personalizing it, you are the one pushing the claims, you are the one that should back up these claims. without that its a completely circular argument.

your confusion about this being an id thing is beyond me. it is ego that devises these problems and solutions, it is ego that forms response and opinion on them, it is ego that believes there can be something better, or that something different is 'better'. it is ego that produces the ever-changing landscape this is all spawned from; otherwise we would have all agreed long ago.

the rest, like I said, I have no desire, nor time to go blow by blow with you, its really very simple.

yawn

They are OBSERVATIONS!

I see that you are in Brisbane. Just come here.

I am really quite a friendly person. I don't keep grudges, not my style (unfortunately some do keep them against me, I can't fathom why). You are quite welcome here any time, and I would love nothing more than just demonstrate it - it ain't that hard to do. It isn't about winning an argument - I would rather let you 'win' and then move on.

Give me a chance?

Until then, should you not keep your powder dry? Isn't that the fair thing to do?

You clearly don't trust me. Is there somebody here in Sydney that you trust?

Send him here, I will be a perfect host. No aggro, no need to.

Then he (or she) can report back to you. I can't be more fair than that.

Please don't tell me that you are afraid - you shouldn't be. This isn't supposed to be about ego. I know one thing, when I listen to music, I don't think about clocks and jittter.

I want to be hooked, I want my FIX.

Don't we all?

Aren't we supposed to be on the same side? Really, I am trying to be as accommodating as can be and bending backwards as much as I can.

I am sure you must know somebody here in Sydney?

All I am asking for is a fair shake.

OK?

BTW, we seem to have another common passion.

Photography.

Got a Nikon D800E and decent amount of Hi-Q glass. But we all know the equipment is only as good as the guy looking into the Pentaprism.

And what's this "shatter of illusions" bit?

Believe me, I am pretty good at that as well.

But never "mean spirited" - I am no Troll.

Music, Visual Magic and and a good Wine. There must be a God.

Re shattering illusions, what do you think of Bybees? I haven't noticed them making any difference, fitted some for a customer, supposed to work on the 'quantum level'? No actual explanation given. Yeah, I get a bit sceptic at times. More than a few times.

I don't trust so-called shootouts. Whenever you have an A-B comparison, the B wins by a LOT, usually by 3:1.

We proved this to a public meeting (ASoN) back in October last year, when two different sources were compared, and the A and B for selected tracks were made at the toss of the coin at the beginning of each round. It proved nothing, and yet it proved something very obvious, that A-B shoot-outs so fond of at audiophile get-togethers don't work. I refuse to take part in them.

We did the same at the European Triode Festival in Holland back in 2006 - some of the contributors here on diyaudio, including Stuart, SY (well-known diyaudio moderator) and we all witnesses the "B" bias factor.

Think about it. Listen and then change a fuse or something, and bingo, the "B" bias factor kicks in and you can hear the improvement the fuse made. Or did it?

The same in retail shops. You want to sell product A, then make it B in an A-B comparison. And the customer is at your mercy. Often the retailer doesn't even understand what is happening, because he often wants to believe what he wants the customer to believe.

Let's try comparing speaker cables, just make sure the more expensive one is B. Want to try the effect of a CD cleaner, ditto. Or demagnetizer. Or vinyl cleaner... you get the picture, right?

So how is that for "shattering illusions"?

Valid observations have to take on a critical faculties and time-extended exposure. You must listen to both for thirty minutes minimum and switching both ways.

Objective listening: If you can actually hear that a live feed in a recording studio sounds like and you can hear three voice harmony, and when the CD comes out, you buy it and you put it in your system and you hear just voices, most likely only two voices are obvious (the softest of the three will almost definitely be masked if definition is lacking), then we have an objective observation, not a subjective one. The you sort out your system somehow, and voila, now you hear three voices in harmony as intended. You are not dreaming. If revealing actual voices and whole instruments within a complex mix, then your ears are not lying to you.

But how many were in that recording studio hearing that there were three voices? They just wouldn't know. Few have heard the full dynamics of a live feed. I have worked for a number of recording studios as well as making and maintaining equipment. I am the guy who has made the infamous "Tube-Station" that is used by a number of leading recording artists in Australia, including Lee Kernaghan, Gina Jeffreyes, Leo Sayer, James Blundell, Troy Cassar-Daley, Col Joye etc.

And I can tell you, some of these guys that produces these guys have very good ears. They are not easily conned as they work up to 20 hours a day with equipment and become very much aware of what is doing what. They are proper professionals. Yet some audiophiles look down upon them - dangerous to judge all to a standard that is not even realistic.

Cheers, Joe R.
