Dear all,

After a rather nervous afternoon of soldering, press Play and first looking whether the VU meters were still jumping up and down, next switching on the main amps - fingers crossed ... imagining the latest Kernel Streaming improvements couldn't be surpassed for better sound ... oh man ...

Those who visited me, shorter or longer ago, expressing something like "never heard such a thing before" ... let's call that history.

Allright, with all the things I did so far, a while ago it appeared to me I had the beautiful opportunity of connecting the "clock source" so much directly to the chips that, well, nothing would be in between it. So, I took it up as a final unplanned little project and thus I got myself a couple of low jitter clocks (3ps max over the whole frequency range), fed them with separate shunt regulated power supplies, and now the net result should be 3ps (max) of jitter. Not that I know how to measure it, but my ears tell me enough ! And I don't even know whether clocks have to burn in or something. Or run in maybe, haha.

There's loads of more tight bass (AGAIN), woman voices sound like beautiful bells, and the Jens Gad (ex Enigma, with the known "grayish" sound in the highs) I'm currently playing, now just show very high resolution sprankling highs.
smirksmirk

The means of connection remains a secret, but I promise you it is still an external DAC.

Well, for all the elements which may make good or bad sound, the *very best* solution has been applied now. There is just nothing left, or it sould be the clock itself with again lower jitter, and which can be replaced in 5 seconds really ...

Before the question comes ... I have over 200 DAC chips here now (alone costing a small fortune already), and I'm in the middle of the purchasing process by now, so please don't think I'm not serious. It took a lot of time though, and while I can only say "sorry" for that, it sure has been for the good cause.
The earlier promised webshop is already there somewhere in the back ground; the ERP system behind it not yet, but this is a matter of spending some time on it. Now I definitely know all the hardware elements to go in, a nice slick cabinet can be made, and this shouldn't take all that long (but undoubtedly longer than I want).

So far for now, and thanks for waiting,
Peter

I can't wait to put the NOS1 up against a real DAC Wink

Is there going to be a faciltiy for driving headphones on your DAC?

Frank, sadly, no. Different from usual, in my case this needs an extra facility which we just as well might call an headphone amp. So, since this is needed, I guess it is a kind of useless to build it in; it will cost the extra money (though it would be an option to have it in), and maybe it is better if people have the headphone amp to their likings. Notice though that I sure would be able to provide one of the (considered) very best, (Fet based) and that there will be space in the cabinet for it.

Please notice that I never use headphones myself, and thus don't know really what makes/brings "a best" headphone amp (you might tell me !). What I do know though, is that it will be in there without a real cable connection other than lead the wires to the jack terminal, which will be 1-2cm. Also, the special design of the cabinet will do some additionally good, as I expect (wait till you see that, haha).

But all together, knowing that it will need an extra amp anyway, I'm not sure people will prefer that.

Happy Easter to you - and all the forum members / guests. Any updates on the NOS1 DAC project of yours?

A short briefing will do, too  Wink

Ok, since you ask ... From off last Friday the 24/384 is a fact. So, all I wanted works now.

Now I am "struggeling" with a display, but because nothing really good is available I may give up on that soon (but a display would be nice !).
It really can't take months anymore now ...

Consider VFD or full color lcd, the former being cheaper and still good looking (see nuforce cd, and many others).
