Cybershaft OP-13 clock was used with JS-2 connected to UpTone Audio etherREGEN (which is available if purchased as a bundle of three items). 

Prefer to sell with the JS-2, which is listed in Power Supplies category.  Also have a etherREGEN for sale if a bundle is desired.  I have posted about what an amazing combination these three items are.

Reason for sale:  Using a Grimm Audio MU1 (streamer/server/DDC/Roon core) which does an excellent job of eliminating noise on its own.  

Price includes PayPal, but does NOT include shipping.  Will ship UPS insured in the original Cybershaft box.   Will include Geistnote Melody 75 ohm clock cable and mini-circuits 75 ohm filter if you don't already have a clock cable.

Truly excellent measured performance:  10 Hz  - 142 dBc/Hz (according to included certificate of performance)

Versatile:  choice of 50 or 75 ohm impedance, ground switch (ground can be lifted). See photo.

Well built:  Heavy (for size), stable, excellent footers, looks like the JS-2'2 cousin.  

Requires an external LPS.  JS-2 is the perfect partner.
