Gott en Himmel!
It has an RCA jack for the SPDIF.......................oy vey.
Waiting on the .pdf to d/l..........and you-know-who to tell us the right way to do it. Cough, cough.

Hi,
Which brand vhc4040 do you recommend or have tried ?
From the datasheet I see that they is quite a bit of difference in their spec's!
Cheers,
Ashley.

So, I can directly feed the DAC modules through I2S from the CDPRO-2M that is waiting unbuilt on my living room?
No need for reclock?
I plan to use a few cm of wire, but before I will search how to implement this not to upset Joko 😀
Yes, I am an irresponsible hobbist 😉
Best of lucks with your new project

I would rather see you use I2S than SPDIF done in an "irresponsible manner".
Not your fault that is is a lousy way to transmit signals.

Dear Joko:
A thousand thanks. That comforts me and reasures me
Abusing of your kindness...errr...would it be any "must read" paper referring I2S transmision that you can point me to?
In order to save me many hours of google search, that is
Kind regards.

Moin Mauricio,
try this:

From memory: max. length for i2s is 20cm. Correct me, if i´m wrong.
For the rest (or most?) of us....spdif AND usb is the way to go. You can use your PC and "cheap" CD-Playa. No need or hazzle to dig in an old playa-model, trying to find a way to squeeze i2s out of it. So Doedde´s concept is right.
For some of us, there is the need to improve this concept. CDM-pro is prohibitive expensive and digging in ~20year old Playa´s isn´t that attractive (for me!). YEMV

Nope, don't have anywhere to point you, but...........
If I was going to run I2S from my CDP, I would look at LVDS. National makes several TX/RX chips that should work. If you can't find the info there, I may have propaganda sheet from them with the right P/Ns.
Yes, USB is probably the future. Especially for commerical efforts. This is DIY. Doing it the hard way can be more fun.
Hopefully better sounding, and more educational.

Just some thoughts:
Soldering these PCM2xxx chips IS the hard way.....
But I hate the idea of booting my CD-playa....so, here is a thread about Digital audio from IDE (CDR->DAE), maybe that´s the way to go.

Many thanks to Carsten and Jocko for their help 😀
It's cheaper than a laptop perhaps?
So, everybody is considering USB as a better option.
Ah! more to study!

Moin Mauricio,
no, USB Audio is only the hype of today..... ;-)
It´s better to look what you have, what´s in your partbin and what you can do. Do it, relax, hear some music, cause that´s what you are looking for.... or am I wrong?

USB is ok. It has jitter too. I believe it is best to reclock both USB and S/PDIF sources. I did with my USB DAC.
