ducatirider Posted August 4, 2020 Share Posted August 4, 2020 What are your thoughts on cascading? There is another device that can accept a 10M input with 3 outputs. I'm a bit confused by the variable frequency outputs tho. Q,What's the usage of 10M input and output? A:10M input, can connected with 10M extern precise standard or synchronizing external 10m signals. 10M output, output internal OCXO frequency, if used external 10M ,output extern 10M signal, and can be used by multiple machines in cascade。 I have a friend with an Antelope master and slave clock and he loves it. https://www.aliexpress.com/item/4000748935888.html Link to comment

Never mind good acoustic recordings, what it does for well constructed electronic creations like Yello's Flag, a truly wonderful album, has to be heard to be believed. Incredible layering and depth. Who would have thought clock cables could make such a difference? Not me. But gave The Melody from Evidence Audio a try and am absolutely shocked by how much better it is than the LV-61S. Thanks for mentioning the cable's contribution to good sound. While I've found (copper) ethernet cables make a difference, which surprised me, I didn't think a clock cable would matter as much.

Exocer Posted August 18, 2020 Share Posted August 18, 2020 I joined the party a bit late and received my unit earlier today. The first thing I did was open it to check if I received the OCXO I had asked for (the DAPU O55A-HSDD) and it is definitely not, but it is the same clock Roberto received as pictured here. I am noticing a slight improvement in imaging. It is powered by an LPSU 1.2. It is the adjust version with all square wave 75ohm outputs. I'm using it with Ghent Audio's BNC cable which uses Canare 75ohm connectors but with Belden 1694A: https://www.ghentaudio.com/part/e07.html Link to comment
Popular Post PYP Posted August 19, 2020 Popular Post Share Posted August 19, 2020 In my system, the addition of a Cybershaft OP13 clock maximizes the effect of the eR. As some others have found by adding an external clock, the overall presentation becomes even more natural and has even greater liquidity and effortless clarity. In my system, the other very obvious benefits are improved timbre, a warmer sound that has more body and density, bass that is subjectively deeper, and clearer high frequencies. All in all, the change is not subtle and the gestalt is definitely more musical and very enjoyable. Given my musical enjoyment before the clock, I assumed that no significant improvements were needed and that significant improvement could only be had by overcoming the limitations of my room through further room treatments and/or software correction, neither of which I wanted to pursue. This particular Cybershaft model has one 10 MHz 75 Ω output, which is switchable to 50 Ω (the stock eR uses 75 Ω). There is a thread on whatsbestforum.com that discusses the Cybershaft product line and the high performance of these well-built clocks. Designer/manufacturer Kenji Hasegawa has clearly put in a lot of thought, time and effort into his designs. The manual provides further proof of that. Communications with Mr. Hasegawa have been excellent.

Popular Post Exocer Posted August 19, 2020 Popular Post Share Posted August 19, 2020 I've had a bit more time with the BG7TBL... and i'm really liking it. There is improved low level detail and "calmness" without a loss of dynamics capability. There is more joy and less fatigue over longer sessions. I will leave it in my chain for several weeks and remove it to see if the differences will be more noticeable. So far this was a really good purchase good find @MartinT.

This would require dual shield with isolation between as I don’t think cable shield should be part of JSSG360 in a coax. Exocer 1 Link to comment
MartinT Posted August 26, 2020 Author Share Posted August 26, 2020 Well, I can confirm that LV-77S sounds significantly better than 61S over extended listening. I use two very short runs (30cm) from BG7TBL 75 ohm clock to the ER and Mutec. As for Belden, I'm done with ordering cables! Coincidentally, I took delivery of a Wireworld Micro-Platinum Eclipse AES cable for Mutec to DAC duty. Amazing performance, it betters my previous AudioQuest Carbon AES cable.

I think it sounds great but who am I to judge... as I've taken closer inspection of my clock, it appears it did not come with the 75OHM connectors I requested... So even with an impedance mis-match I like what this clock is doing with the Belden cable, LPS 1.2 for power and only clocking the Etherregen. Have reached out to the seller to confirm next steps but this is annoying . I only noticed it because someone PMed me to ask which one to get... and my connectors definitely appear to be 50OHMs based on the looks of it. Link to comment

Popular Post Superdad Posted August 26, 2020 Popular Post Share Posted August 26, 2020 1 minute ago, Exocer said: Yes, I am. Yes, despite the BG7TBL clocks being labeled "Max 18W", I too have found that I can power mine with an UltraCap LPS-1.2 (set to 12V of course). In fact, based on LPS-1.2 case temperature after a few hours, I am guessing the clock is drawing only about 500~650mA. It likely draws much more in the first few minutes while warming up the oven of the OCXO, but even that is still within the 1.1A capability of every LPS-1.2.

R1200CL Posted August 28, 2020 Share Posted August 28, 2020 This tread have been interesting. Thanks to everyone and especially @MartinT I was total against external clocking. But for $92 and free shipping https://www.aliexpress.com/item/4001245799329.html?spm=a2g0s.12269583.0.0.358ed1dcNlVLxb I just have to try. I will get the FE180 clock. Not the DAPO. Hope is as good as DAPO. I will either power it with a series of two LPS 1 or a Gophert PS. I think I probably use a 30 cm Belden Cable. Either 4694R or the older 1694A. However I’m considering JSSG360 to be applied. Looking forward to feedback from others. I wonder why not all digital interfaces could be fiber ? No more shielding, impedance and ground loop/noise discussions. There should be some new standards covering this. HMDI / USB / SPDIF / AES/EBU... Exocer 1 Link to comment
