Dont be disturbed, be happy!
Most DAC's of today get clocked (reclocked) by the incoming signal. DAC as such, The DAC Clock is just a slave.
If you want to go the linked route,
Guido at Tent Labs specializes in that.
You want the DAC as a master and the transport as a slave.
Tent Labs is the best I seen so far as he uses a voltage controlled clock link.
With my work sometimes is not good to link the clocks.
(Induces noise) Superclock has one output... (I believe).
LClock has two output, but the AUX clock output is not great... it does not compare to the main output.
The reason I suggest two separate HQ clocks in each unit,
So you would not have the common HF noise contamination in the clock signal. Plus depending on the design, Some DAC's can reclock to the incoming data, using its clock as a slave.
I specialize in TacT Audio, Full Digital Audio.
The 2.2x has 6 clock oscillators, and amps have 2 clock oscillators. I found using HQ speced OEM style Oscillators,
(Accuracy -+10 ppm, jitter 10ps) with in the 2.2x works very well.
Three main specs you want in a clock is, Accuracy, stability, low jitter.
I found with most of todays gear, having very low jitter is most important, along with stability and accuracy.
Linking clocks between components can easily induce jitter. Using a Jiterized clock, you can be sure your data signal is going to be jitterized too.
This is why I prefer separate HQ clock in both units.
Now if we use an Iclock master clocker, or similar device,
There is less of a chance for errors.
I would like to add, I do not suggest you purchase a Superclock, lclock, etc. and install yourself with out proper test gear. Improper clock installs can have a huge effect in degrading sound quality.... I have seen this many times...
