Ok, anybody else having build a ADC unit?

Anyway, I noticed that clocking becomes quite difficult when you try to make a really big unit. My unit has now 12 inputs and 24 outputs. It was really hard to do that with wires. It is really sensitive. As soon as you touch a wire of the clocks or it is a little bit moved because you have moved the total unit you have distorted sound. Then you have to rearrange your cables by moving them a little bit.

This problem becomes bigger with more modules you use. Eg. with only using 4 ADC and 4 DAC modules no problem but with more modules the problem rises. Later I changed the problem with redoing the wiring. But it has eaten a lot of time to find the best wiring scheme via try-and-error.
Therefore, I decided to change my plans, and do first the design of a backplane/carrier pcb for the small modules. On this carrier board the modules can be plugged in exactly the combination you need. It will also provide a clean supply voltage for the analog parts. On one side there will be a standard connector for extentsion (eg. if you need more channels) with a second board while on the other side you'll have options for connections to the outside world (Sub-D, XLR, BNC with analog audio, AES etc on it).
What do you think of this? Interested? Useful?
