After upgrading to the AfterDark Emperor Double Crown for my ER I have a BG7TBL 75 ohm clock and Ghent cable (~14") that I can send on to someone who is ready to try external clocking of their ER.  I ran this for 8 months direct to the ER w/o a minicircuts filter, I was unable to get a scope on this to confirm square of sine wave but it worked great as is.  I just ask the recipient cover shipping but else I'm happy to send it on FOC.

 

PM me and we can organize the bits.

Although I posted this in another threat but as this is the "clock" thread, I'll also post here. 
I just tested the Mutec Ref 10 clock outputs and they are galvanically isolated as also stated in the manual. So no problem using it simultaneously on otherwise also isolated devices.

Thanks for sharing Zoltan. Could you let us know how you tested?

With a multimeter. The "continuity"  setting gives no beep when touching the ground part of the output terminals. When measuring resistance, it stays OL, in other words, there is no circuit (well, that is clear from the first test, of course).

Further to this @Mihaylov, is this true (i.e compromising the moat) even if the clock in context has “Galvanically isolated outputs” to feed devices on the same network. 

e.g Ref 10

Folks,

 

When I changed from the supplied cables (Belden) of my Emperor double crown, to high end ones, the improvement was so dramatic, it was natural to speculate if the improvement could be larger than the effect of breaking the moat to my two ER's.

 

So I ordered another set which just arrived.  They have been installed and the moat is broken.  The answer is a resounding yes.  Huge improvement in musicality.  Moat now irrelevant. Simply impossible to tear oneself away. 

 

I should mention here that all my equipment is earthed to an active grounding box from Synergistic Research.  Differences of effectiveness of moat were clearly audible with and without the grounding box earlier (using mediocre cables).   Those differences are now swamped by the effect of using good clock cables.

 

Suddenly its easy to believe Caelin Gabriel when he says good clock cables can bridge the gap between digital and analog, all else being equal.   This is logical  - no jitter (perfect timing) means no difference between the two, and good cables are critical to precise clock signals.  But its not intuitive and I had discounted it as another advertising gimmick until I actually heard it myself.  I'm now thinking clock cables are the most critical of all cables in a digital system.

Which ones ?

[aubreybobb]

Custom. Made by Aurealis Audio.  Using Dueland 99.999 silver, insulated with teflon and an outer mesh.  Very nice plugs (forgot the name), beautifully finished.    Price 30 CM around Aus 130/-,  1M around 160/-, so very reasonable, great bang for the buck.

The only Duelund silver i can find on internet is flat ones. Except this one:

I guess you use 75 ohm BNC plugs ?

I have never seen a true 75Ohm impedance cable that is not coaxial. It has to be very precisely engineered geometrically. My understanding from John Swensons explanation on this that impedance matching is one of the key factors when it comes to clock cables that transmit square waves, especially at such short distances because of reflections. I would like to know how such a "home brew" cable measures when it comes to impedance. 

[aubreybobb]

I have not measured it but Geoff at Aurealis sold it to me as a 75 ohm BNC.

 

The thing is that my first order for 30 cm produced such good results that I went ahead and ordered the 1metre ones which turned out just as successful.  I have one more external clocking option and I will probably order one more for that. 

 

They are not flat and are definitely coax. 

 

Please contact Geoff at Aurealis for more info.  In case he is running out of the Duelund, which I had the impression he was,  I would be happy to add my 1 metre order to anyone elses order so he can obtain more.

That was also my experience with adding a very good clock cable.  For those who use an external LPS for the clock, you might want to experiment with the DC cable too.  I was surprised that the DC cable made a difference.  Not as large as the clock cable, but still worthwhile if you are at the point of tweaking the little stuff and want to hear all that the clock can do.

It's very Interesting that he said that.  The Shunyata clock cables I use were significantly better than generic clock cables, but generic cables tend to stink so that came as no surprise.  I wouldn't have imagined though that they were the "most critical" of all cables in a digital system, but you made a really good argument.

Hello Tungsten lovers 🙂

 

Since suggesting the tungsten cube was such a success it gave me another idea

Glad to share another tungsten DIY

This time went for isolation feet filled with Tungsten powder. 
pretty simple actually

got some pipe connectors (I chose 6.5cm outer diameter with 0.5mm walls), cut to desired height, spray paint black, glue sorbothane circle on bottom, fill with tungsten powder, glue top sorbothane circle. 
 

The ones I made (total height 4cm) came out 620 grams each!

 

 

Thanks to Martin T for sharing this tip. I have purchased the same Chinese clock and experienced a worthwhile improvement to my sq via etherregen into dcs network bridge. 

 

I want to try the 25mm tungsten block heck but it seems 25mm2 blocks are priced Ike $75?? Ebay is selling 10mm2 ones for much a cheaper price. 

 

Any alternatives or do you think $75 for the 25mm2 is worthwhile?

New to this thread, so apologies if this has already been answered. I have gotten an external 10 MHz clock with to output levels. One of 900mV and one with 500 mV. Any advice on which one to use with the Etherregen?

 

Thanks

Go with the 900 mV.

I have to admit that I had been largely ignoring this thread.  I was delighted with my ER powered by a Super3 and the last thing I wanted to do was add more boxes.  A change to a different DAC brought with it a reference clock input so I ended up adding another box after all, a REF10.

 

This brought a nice improvement to my DAC, which was my primary goal.  I had been listening mostly to music stored on the internal drives of my K30, so I considered the network to be less important.  But on those occasions when I opted to stream from my NAS or Qobuz, I found that I very much appreciated the improvement the REF10 brought to my ER.  
 

I was asked if the REF10 on the ER brought improvements when listening to music stored locally on my K30.  I thought that there was no way this could matter but to my surprise it did.  Best I can figure is that the clock improved the ability of the moat to work its magic.  I’m just curious though if others have observed this as well.  Do your files stored locally sound better when a reference clock is applied to the ER?

 

I should point out that I left the the clock cable connected to the ER when doing my comparisons.  I only toggled the switch followed by cycling the power.

[aubreybobb]

Hi Kenny,

 

I have a cascade of 3 switches (Sotm + 2 ER) from the router and NAS to a Network Bridge.  Unfortunately my DAC's are in my speakers and cannot be reclocked. 

 

My clock is a double emperor dCS version and all the switches and NB are externally clocked.

 

The improvement from BOTH the NAS and Router is enormous.   

 

Interestingly enough,  there was a big jump when I changed the supplied clock cables to hi end ones (custom Dueland silver) - the improvement was almost as big as adding the clock.  I know this is not a placebo because with the supplied cables (van dammes) I was only able to clock 1 switch.  Adding external feeds to the other switches only deteriorated sound quality.  They were 'breaking the moat' - cancelling the galvanic isolation of the switches due to common earthing. 

 

Once I improved the clock cables the improvement in SQ was so dramatic as to swamp this effect!  According to Caelin Gabriel, good clock cables reduce jitter enough so that they can bring digital up to analog levels, all other things being equal.  The cables are as important as the clock. 

 

Hope this useful.

 

Best wishes, Aubrey

I use Shunyata clock cables but only compared them to cheap generic cables that I purchased from Amazon to get started.  The improvement was profound.  I do think saying that they made things sound more analog would be correct.  I really like the density of tone that come with use of Shunyata cables.

Has anyone compared the Mini-Circuits low pass filter with the Crystek one? Any difference?

Hi Audrey,

 

Contacted Geoff on availability of 3x and 7x of 1m each for this cable to try replacement of an assortment of pro audio Canare, Apogee etc. for clocking of my upgraded Denafrip T+ to Hermes ddc and also 2x ERs with double crown AD clock and China clock b4 Antipodes EX and between EX and CX ... thanks.

 

Will update my findings if I managed to do so .. since ok pricing and not those crazily price toward 1k types that I do not support especially with up to 7 pcs needed and usual marginal SQ impact experienced from cabling unlike technological one  😆

 

Thanks again and cheers.

[aubreybobb]

Hi Richard,

 

You will not regret it!  Pl keep me posted.  My order for the final one I needed is in place and I hope to get it next week.

 

best wishes
