One big difference when comparing separate dac/trans to a one box cdp. The clock/s. In separates you have a clock in the dac and a clock in the transport, they are not sync'd together, in a one box cdp you have one clock for both dac and transport so these are sync'd together. 

Ten Labs use to made a an expensive $800 board kit that sync'd both separates together, but you needed to do some heavy surgery, and then have a second connection link for the transport to then run off the dacs clock.

George,

If the transport is running spdif OP to DAC yes, you are correct.

However most of these CD94's -> KDACs are running I2S to DAC so they are in fact synced.

And the last few zenclocks I installed had an I2S reclocking / line driver that re aligned I2S signals directly to clock.

That's synced!

And that's all the Marantz CDA-94 DAC had as an input, spdif.

So the clock in it couldn't be sync'd to a transports clock. 

 

And if anyone wants to mod their CD94 MkII to NOS here's how to do it.

As stated, most people run I2S between CD94 (used as transport) and DAC.

 

Even in a one box player it's worth reclocking the I2S before it enters the DAC chip(s).

The clocks timing gets pretty corrupted before it reaches the DAC.
