The 4694R may well be excellent, but I have yet to try it. I am using 30cm Canare LV-77S and i can thoroughly recommend it.

That's interesting. Seeing as I'm giving it a well regulated 12V already it may pay to take out the regulator and link across, or else set my PSU to 13V.

MartinT Posted August 30, 2020 Author Share Posted August 30, 2020 Actually, looking at the spec sheet, dropout voltage of 340mV means that 12.5V input would suffice to keep it operating.

MartinT Posted August 30, 2020 Author Share Posted August 30, 2020 No, of course you're still hearing the benefits of the OCXO. If the regulator is not getting sufficient to cover its dropout voltage, it will simply pass current through without further regulation. I've now trimmed my LPSU to exactly 12.5V. I'm listening and it doesn't sound any worse! I'll let you know long term if I hear any differences.

Popular Post MartinT Posted September 3, 2020 Author Popular Post Share Posted September 3, 2020 I'm using Canare LV-77S as my clock cables. I was encouraged (see above) to compare it with its obvious competitor, Belden 4694R. The Canare comes with beautiful Canare true 75 ohm BNC connectors while the Belden comes with black chrome Neutrik connectors. Both are very high performance 4K/8K video cables. I've been swapping back and forth and I'm damned if I can hear much difference, which may simply boil down to style. I wouldn't be able to reliably identify one from the other. Since the LV-77S was noticeably better than the LV-61S, I've probably reached the limiting performance for 30cm of either. Good experiment, though, and only cost me £16 for the Belden.

Popular Post MartinT Posted September 18, 2020 Author Popular Post Share Posted September 18, 2020 <later> Having done extensive listening, I can say that tweaking the OCXO LPSU to 12.5V has improved performance, so the low dropout regulator is removing more noise from the DC rail. I've settled on the LV-77S clock cables as performing well. The EtherREGEN itself enjoys 12.5V LPSU power and a Black Ravioli grounding box connected to the ground terminal. Both ER and OCXO sit on Black Ravioli Pads. I have ordered a larger heatsink to bond to the top of the ER in order to cool it down some more. A MeiCord ethernet cable from the router feeds into the ER and a very short 12cm unshielded cat 6 cable feeds my Asus streamer. This configuration gives me superb insight into the music so I'm done with messing around with it.

My Cybershaft took a while to warm up-- probably two weeks (vs. a few hours for the cell-tower-based gear) before a real difference and then a month to complete the process. Warm-up time for the DAPU is only a few minutes. Settling time from cold to the full effect is less than 24 hours. I guess they are designed that way for fast recovery if a cell tower loses power.

MartinT Posted September 27, 2020 Author Share Posted September 27, 2020 Before you decide, think about whether you need a GPSDO unit. The BG7TBL is not GPS disciplined and features decently low phase noise. You will not improve that with the GPS, you will be adding complexity and more noise, all for long term drift improvement which is not required for music playback.

Is this each time after being powered down? I will obviously let it run... around the clock. B) Is 12,5V VS 12V really a thing? A) Yes, definitely leave the clock running, OCXOs are designed that way. B) For me, yes, 12.5V seems to fully enable the onboard low-dropoff regulator and gave me a small boost in SQ over 12V.

MartinT Posted November 7, 2020 Author Share Posted November 7, 2020 A modification for my OXCO master clock. This was suggested in the thread above by @GMG. The idea is to bond a cube of tungsten directly to the top of the Chinese oven-controlled clock module inside the BG7TBL. I ordered a 20mm cube of tungsten on eBay and it arrived this morning. I used 2-part epoxy to tightly bond it to the top of the DAPU OCXO can. It didn't take long to harden as the clock runs at about 70°C. It should provide two benefits: 1) vibration damping of the sensitive OCXO by dint of its heaviness; 2) temperature stability once the cube comes up to temperature, helping to prevent temperature variance distortions. I've just had a listen to two tracks and my immediate impression is that dynamic transients have even more snap to them. Donald Fagen's Nightfly and Kamakiriad are outstanding recordings and sounded pretty damned good, even cleaner than I remember and with outstanding starting and stopping of transients. I'm leaving things to fully stabilise and will have another listen later this evening.

These are commonly used to attach heat sinks to electronic components. I do have double-sided thermal tape, but I didn't want it to be a lossy coupling, so I used epoxy. This way the cube has the full resonance damping effect.

MartinT Posted November 7, 2020 Author Share Posted November 7, 2020 1 hour ago, GMG said: But, epoxy has poor thermal conductivity. So heat will not travel efficiently through the epoxy to the Tubgsten cube. I don’t think it is an issue here since the you probably used a very thin layer of epoxy, plus the cube is very small so even if it does create a thermal deficiency it will be small and the oxco likes it warm anyway 🙂. Yes, I used a very thin layer of epoxy and squeezed it down, ensuring that the thermal barrier is thin.

You want insulation, a warm jacket, not a piece of metal glued to your chest. If you could do such a thing, sure you'd be cold while you're warming up the piece of metal. However, once you and the metal have thermal equilibrium, it would protect you by supplying heat back through any sudden cold snap. Thermal stability.
