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

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.
