Curious what ppl use to replace the crystek 957 on pcb ? the acko clock seems good 170db at 90khz , when wil lyou use a oxco over aa crystal oscillator though? thos oxco looks like a drop in and good specs

The Acko clocks are the best, but they are most expensive too. Also they have strict power and output loading requirements. There are versions with and without squaring, which eventually you will need a squared output.
Somewhere in-between Crystek 957 and Acko are Iancanada SC Pure. They do need clean power though. Cestrian's Clock and Reclocker board can produce very good results, and it includes an excellent clock buffer. You might read some reviews of different clocks by users towards the middle and end of the thread. Even Crystek 957 sounds better than usual in Cestrian's board according to some user reports. https://www.diyaudio.com/community/...r-jlsounds-i2soverusb-pcm2dsd-rtz-dac.423401/

BTW, it doesn't matter much for an audio dac what the phase noise is at 90kHz offset from the carrier frequency. Trying looking at 1Hz and 10Hz offset phase noise numbers. Likely more relevant to what you can hear, including for imaging precision (IMHO, anyway).
All the above having been said, replacing a Crystek with something else on the same PCB can give much less than optimal results. It matters a lot how the clock board is designed to get the best out of most clocks.
