Any news about the upcoming Leo Bodnar 10Mhz OCXO based master clock?

Finally the clock is here. Excited.
I think i have downloaded a set of settings. Anyone kind enough to share with me the optimised setting so i can compare. I dont know how to upload pictures.
Thanks.

The settings are on page 6 of this thread.
Do let us know how you get on with it

Initial impression is good. Not sure I did optimised the clock. The clock is power by LHY dc power at 8.85v. Cant adjust to my initial expectation of 8.55v. the clock is on isolation cones and 500gm of weight. Clock cable is the harmonic tech.
There seems to be more body to the imaging. Without the clock it seems more diffused. Seems to have more highs, also accentuated the sibilance. Bass gained weight. Seems to have more power to kick drums. Overall the sound is warmer. Soundstage depth and width dint seem to change much.
Will let it run in more.

Accentuated sibilance indicates that not all is well. The power supply may not be sufficiently low noise. The HT is a good cable so it's not that. Perhaps also look at a grounding box for the streamer or whatever the clock feeds.

Will running in make a difference?
I can sure get the 8.25v power supply and grounding box for the R26.

This can make you or break it, John and myself have tried loads of cables, and they all sound different. l would hold off on the PSU, sure 8.25v is the optimal, but so is the quality, l use a Farad Super 3 at 7volts, and it works well. lf your on a budget, l can recommend a Zero Zone psu,with can be adjusted from 12v all the way down to zero. "Atoz" runs this set up, and it works really well, considering how cheap the psu is. |

Im using Harmonic Technology DC III bnc.
Will take a look at the dc power.

Can't say l've used that cable. l tend to DIY, personally my favourite is TFLEX 405 cable, but from experience it can be fussy, actually the most sensitive unit to cables l've ever used. Give it a good burn period first,and report back. Have you changed the pigtail lead inside the R26 that runs to the BNC socket? That is a major bottleneck |

For testing, i took used the usb cable to supply power from my mac mini. The highs sounded smoother, but the bass lost the weight compared to the lhy power supply.
Not too techy in terms of changing the bnc in R26.

Check all your cables. Try to avoid cross talk. This can happen if near a mains or dc cable.
It might take time to isolate the sibilance issue. This can happen when your system gets more open and could be down to a number of factors.
The good news is it's not the Leo Bodnar. Once solved more goodness to come. However it can take time to find out what is causing the issue.

It is for testing, seems like the clock is sensitive to power supply. Will let it run in. |

A quick test method, get some aluminium tin foil,and wrap around your cable.. that should help things. |

Wrap around the BNC cable? Yes on BNC cable, and power supply cable. it's just a quick method, it acts like an additional bit of Sheilding, of course, moving them a few inches may solve this as well. |

After running in 8 hrs, added aluminium foil wraps on the power cable and bnc cable and sort of aluminium to cover the clock... I had an omg moment...the sibilance is almost gone.. Will report back more.. do u also wrap up the antenna? 😅

No need to wrap the Antenna.
So glad you are getting a decent sound.
