Thanks, that was the page I was looking for. The specs for their clock are as follows:

 

FemtoSecond Galaxy Clock Specifications:

Phase Noise at 0.1 Hz -67 db

Phase Noise at 1 Hz -99 db

Phase Noise at 10 Hz -134 db

Phase Noise at 1 kHz -157 db

Phase Noise at 10 kHz* -157 db

Phase Noise at 100 kHz -157 db 

 

If you get me the phase noise figures at the same freq for other oscillator (Crystek or other) I will calculate the jitter for you to make the comparo possible.  

It doesn't the carrier though.

The numbers for Pulsar clock you can find them here:

@AudioBang

Interesting report. I have a Crystek 100 MHz clock in my DAC and I was thinking about a possible Pulsar upgrade.

What low noise PS did you use for it?

ADM7150 CORE - THE 1.7 nV √Hz LDO

 

 

 

 

Is it worth considering the LT3045 regulator for it?

Just curious, is your DAC using an ES9018 Sabre or ES9038PRO?

ES9038. It is a LKS Audio DA004 DAC.

In the previous model, DA003 with ES9028 some people changed the master clock to a Pulsar.

I think it is possible - but don't quote me on this - to swap ES9018 to ES9028 because they are not just pin compatible but also output stage can be the same. I believe ES9038 requires higher output.
