Master Clock for your EtherREGEN

it is not advisable to disconnect the bnc cable from the clock if it is on .

This requires explanation. 
 

Can you short the signal, which lead to damage ? Maybe John can enlighten us ?

It is for safety reason for audiophile devices.

@AfterDark. This doesn’t make sense to me. Any device in the other end must be powered off, and you don’t say it’s for the clock itself. And you can’t say that your clock can potentially damage other equipment, or are you ? Time to look for a CE sticker 😂

I have another coming from Mini-Circuits UK.

It’s still not listed as available. Did you make some custom order ?

The AliExpress price is quite high.

I need some help buying the minicircuits 75ohm filter.

Did you notice Aliexpress link in post above yours ?

Alternatively, why not purchase the 50 ohm version?

This is what they told me:

 

”The BLP-10.7-75+ is a non-catalogue part and is not recommend for any new designs”

I will provide more insights later...after a month or so of listening...and experimenting with clock cables and power cords.

It would be nice to have some pictures from the inside.

Alex had mentioned that shielding is the important quality for sine wave clocks.

If that’s the case, then adding JSSG360 should be a winner. You know where to buy 😀

and it is impossible for me to measure if there is a ground loop or that the B side is broken etc.

That’s very easy. Just ohm the connectors.

this cable has been recommended and is stamped as good for the B side. However the plugs are metallic.;)

 

I'm going to stop the off topic because this is the masterclock

 

 

 

This cable has absolutely no connection between the plugs. Hence the plugs add better shielding as well. 
The shielding around the cable works as a Faraday Cage. It’s not connected anywhere.

are metal plugs bad?

Yes, if it’s following the standard. No, if it’s done as the Ghent cable or Audioquest Vodka.

AudioQuest Vodka is good for Side B etherregen ? why ?

I was saying it has metal plugs, that isn’t connected to the shield. Otherwise I think paying anything more than Ghent is asking, or even the cheaper Bluea Jeans, is a total waste of money.

 

So again ethernet cables that has connection between metal plugs isn’t recommended, as you may risk ground loops. And again, metal plugs is good, as they have good EMI/RFI protection. Hope this is clear now.

The size package 24x24x15 cm. 
 

Huge span between phase noise 1Hz and 10Hz. If I really got 140, it’s fantastic.

Good documentation with this item.

You did even better than me (for a King) of -108dB and -138dB respectively.

 

I'm very happy with it.

Did you open it ?

Also, I would honour Adrian's wishes not to publish internal photos.

He hasn’t asked that.  Actually people should know what they’re buying. 
 

You will be surprised what’s inside 😀

Very.

More to the point, though, having heard what it does I really don't care what's inside.

Interesting POW.
If you’re buying a 911 with a beetle engine, but the HP is stated to be 300, (equal to an original 911), I wonder if you would say the same 😀

I've asked you before: have you actually listened to your AfterDark?

Not, yet.

If so, it's a service to the community and to potential buyers.

It seems people isn’t much interested in knowing what’s inside the box.

Do you have an AfterDark clock your self ?

 

I like to see others post their measurements from AfterDark. Mine attached.

Your certificate is from April 2020!
Your data is much better than that indicated on the site. they are equivalent to an emperor crown while you have the King version. very strange !!!

I agree it’s very strange. I don’t expect @AfterDark. to explain why one year old. 
Given the difference in price, and only 5 dBc away from the Eva, maybe it’s the King one should aim for. 
 

There may, or may not be an availability of already measured King clocks. But maybe potentially buyers should ask for measurements upfront. 
 

If I purchase a second King, I definitely ask for phase noise measurements up front. 
(I will need time to find out of a splitter is enough, or purchase a second one is preferable). 
 

I hooked up just an hour ago. So need some time to evaluate. Sounding good.

Exactly this.  There are countless OEM arrangements out there, from simple re-badging to module provision.  Using another design does not in any way denigrate the product if it performs to specification.

 

Performance selection and categorisation also happens, which is what I believe AfterDark are doing.

Yes, Adrian is definitely re- badging. You can purchase his clocks fairly cheap on AliExpress or eBay. 
To me it has a god value that the clock is put in box and properly (hopefully) measured. Mine is above 20 dBc compared to official data sheet. One could question that, but to my knowledge so far it’s possible for a limited percentage of a batch to obtain better numbers. Also these clocks isn’t made for audio, and may focus on other parameters as more important in data sheet. Like age. 
 

I think he will only gain being more open about what’s he actually is doing. It takes time and money to do what  he is doing, and of cause that’s an added value, he shall be paid for. 

I must say that when open my clock, I was thinking of blaming him for a fraud, but I probably more into purchasing a second clock from him, when the wallet allows 😀

Still, I won’t mind a second measurement of my clock.

Afterdark was quick to make a special ER square wave version!

The clock (and PCB) he use offer square out, so it didn’t take him much effort to offer this.

 

Those that has purchased the Queen should open it, and confirm this. Don’t you ever think you got a special design clock. You never did. It’s all a standard available on AliExpress. 
 

(Nothing necessary wrong with that).

Given the serious implications of your claims, I think it is only fair to @AfterDark.that you post links to the Aliexpress clocks which you allege that Adrian is using.

 

Btw as far as I can recall from the various threads, I do not think that Adrian ever claimed that his higher tier clocks have any "special design", just good old calibration and measurements to meet the minimum stated specs of each specific tier. 

I think you easily can do this yourself as an owner of a AfterDark clock.

Attached is my AfterDark certificate.  It appears to be several steps above a King in spec.

And page 2 ?

@Superdad or @JohnSwenson

I’m using the Cybershaft splitter with Mini-Circuits to feed both the EtherRegen as well as my SU-2 from the very nice AfterDark clock I’ve got. The King has been powered with both LPS-1.2 and dual LPS-1 in series. 

 

However the EtherRegen stops working after a few minutes in this setup. So I need to pull power cable quite often. Setting it back to internal clock is OK. Or removing the splitter I think. 
 

Do you have an explanation to this behavior ?

Do you use equal 50 Ohm Clock cables delivered by Afterdark?

No, I will try that.
