Anyone need a 25MHz Crystal/Clock to theirs Buffalo switch, NUC`s or? At Andrea Mori`s Groupbuy at Diyaudio.

Please note that I am posting here as an audiophile only, and not as a representative of Sonore.  Sonore cannot recommend or support anyone attempting to modify its components!

 

Finally got around to building up a DriXO WTMC @25 MHz, and using it as an external Ethernet clock for my Signature Rendu SEoptical.  I am powering it using a specially tuned Salas uBiB shunt regulator.  I mounted the StS board directly to the main board internally, right where the previous Crystek 25 MHz oscillator was (before its removal).  Everything is boxed up and working perfectly.

 

Indeed, there is a significant performance benefit, it was a Wow! moment within the first couple of notes, even with start up from cold (before the WTMC had a chance to stabilize).  This result surprised me, as I was really expecting there to be no significant difference, I was wrong.  It seems that there is much more to understand about Network audio distribution-fascinating and interesting to say the least.  I cannot even begin to speculate on all of the implications of this result, but for now, I can enjoy the improved sound quality in my system!

Uh oh, now @vortecjr is never going to here the end of it from @R1200CL--demanding that Sonore build external clock provision into the whole Rendu series...  

Uh oh Alex...  Now you have done it by pinging folks!  I was attempting to stay stealthy here by posting in this somewhat obscure thread.  Hahaha.  Although of course I have been sharing my experience with the "greater Sonore Domain" and advising to include 50 ohm external clocking compatibility in future Sonore products.  Not sure why the EtherRegen is 75 ohm?  My research indicates many more clocks available with more common 50 ohm connections, but perhaps even more important, there are many more options for fantastic clock cabling (via Pasternack) at 50 ohm without having to go to insanely priced "audiophile" options.

BTW, this clock is around -100 dB @2Hz, and -130 dB @10Hz for a 25 MHz signal, subject to variations in the individual SC cut crystals, and the performance travels well over cabling as it is a sine wave clock with a sine to square converter at the receiving end.  Of course it can do even better at a 10 MHz masterclock frequency.  Given the SOTA in the DDS chips these days, I now accept it makes sense to use a really good external master clock source @10 MHz with an internal DDS to derive various need frequencies internally for DACs and network devices.
