Master Clock for your EtherREGEN

Bad numbers. 
 

If it was 150 dBc at 10Hz, it would be very (extremely) good. 
 

It may help. Most BG7TBL is 50 ohm natively. (As is AfterDark clocks). 
 

Standardize on 50 ohm is good. Not everyone agree. EtherRegen is also available in 50 ohm.

 

You may consider 5V clocks as maybe easier to power them. Same clock can sometimes be available as both 5 and 12 V.

 

I recommend the AfterDark version you can afford instead of BG7TBL 😀

 

Hi R1200CL,

 

Sorry but I do meant dBc if this is what matters and also only speculated since rubidium clock while not having actual x72 specification.

 

In consideration of Afterdark options but hoping more educated bros here can comment on BG7TBL with Rubidium clock at usd680 which was not shared previously.

 

Not the recommended usd2k double crown version for me though as it will be too much $ for EtherRegen at usd640 in my opinion .. imagine if we have 11 versions of EtherRegen from usd640 to 3000 and you have the usd640 version 🥺

 

Cheers.

It’s the 1 Hz 10 Hz numbers we’re looking at. Understand ? (You had a K there, meaning a much higher number, and doesn’t help at all).

I advise purchasing a reasonable priced AfterDark clock instead of BG7TBL. Ask phase noise numbers upfront. (Don’t necessary follow his naming convention). Then get a confirmation about return policy and options. 
The option is to just test AliExpress.  But there is no guarantee what you get.

Hi R1200CL,

 

Yes and same thinking too ... and for me, it will Queen at its price level and nothing else.

 

But asking for phase noise # do not make sense and AD need to fix it if this is the case ... each of the 11 versions of AD clocks are already with declared spec and buyers cannot and should not be subjected to draw of luck 😅

 

Cheers.

I like to start a tread about clock cables. Does there exist one already ?

Posted in that tread. It’s a mail I got from a manufacturer. It seems shielding is the main thing to work on. Or isolation in general. Cables shouldn’t matter. Please continue discussion there.

Can I assume that the reason I don’t see the Mutec Ref 10 se120 mentioned much is because of its price.

 

It seems to tick all of the boxes. Square, 75ohms, isolated outputs, very low phase noise (if I’m reading the charts right - the only knowledge I have of clocks is from this thread).

 

Or is there something I am missing?

Nice spec beyond afterdark offerings and configurable .. square, sine, 50ohm, 75ohm etc.  German quality, detailed specification and on top of their game 👍👍

 

Usd7k indeed but not sure what can be heard in MY setup 😄

 

 

 

[richard_crl032]

For completeness of mutec clock offering and specification ... se120 supposedly much better sounding  🤔

Yes, it’s super expensive and I doubt I’ll ever have it my system -but- I was curious why it was almost ignored.

I got weak and just installed the emperor double crown into my system after ordering it 3 days ago ☺

 

Get to use sidelined wdye eye bnc cable from cold storage and awaiting for ghent audio one as current needed 2m one is with 2.5mm oyaide that did not worked ... now running with Meanweĺl smps and mors listening thereafter 🥲

 

[richard_crl032]

Wow !

 

Finally after 5 hrs and family stopped watching Netflix for me to hear the obvious improvement brought by adding the AfterDark Emperor double crown ! 🥳🥳

 

Will skip all the usual waxing to say:

 

- the AfterDark double crown while diy looking is one component together with Uptone ER will not leave my system together

 

- music just pops ... wide and deep staging, extended highs, pronounced critical midbass for body and further PRAT factor ... fast, dynamic and yet delicate, real sounding midrange but no tube-like addition like some reported

 

Audition primarily via usual full flac broadcast internet stations of HiOnLine and Frequence 3.

 

YMMV but my system easily discern with and without this latest toy  😍🍻.

 

Goodnite and I am a happy man ... again ... in this no-end audiophile pursuit and noting that the cost of ER and this AD clock alone can almost get some decent streamers.

 

Cheers.

Hi,

 

Chanced upon Roon Community forum and indeed the case for me:

 

https://community.roonlabs.com/t/etherregen-with-an-afterdark-ocxo-clock-wow/161630?page=2

 

Well, great material sounds fabulous. Mediocre material remains mediocre. And poor source material now sounds even more like crap.

And if you spend all your time listening to 60’s rock, 50’s jazz, or 40’s blues; please don’t bother.

 

Good news is then that my system is "high end" enough to discern with indeed "fabulous" sound quality from already nice full flac, 320kbps or even 192kbps e.g. "The Wave - Relaxing" stations. Bad news is that favorite local internet fm radio channels at low 64kbps had not improved to beat my Bel Canto FM-1 tuner running directly to the Denafrips T+ ... they indeed sounded worse to be almost unbearable especially when switched from full flac or 320kbps stations.

 

I understand the usual audiophile saying of a "revealing" system but new to me that a single component can be "revealing" to such an extreme extent.

 

Any reason or even rectification actions ?

 

Aside to Adrian,

-------------------------

Should I try the low pass filter with my 75 ohm sine wave Emperor Double Crown that I did not received ? Perhaps poor quality sources are having more garbage in the higher frequencies ? Re-read John's white paper and cannot say if indeed low pass filter affects low quality sources only. Cheers.

 

Cheers.

Just a quick update ... was using a meanwell smps for the double emperor while waiting for ghent's canare dc.

 

Ghent's cable arrived and another obvious SQ improvement with 12v from a dual 12v output zerozone lps which also power my mesh node. The ER continues to be powered by its stock smps.

Something to consider:

I will be buying this power supply later this month. Looks promising. 

[richard_crl032]

Hi R1200CL,

 

Thanks thanks .. LT3045s are nice but think I will stay with stock smps for the regen to avoid any concern raised on grounding by Uptone that is beyond my understanding.

 

Excessive boxes as it is in my system and then another powercord to consider .. already with sgd10k on powercords which is I also do not know how it ended up this way in this crazy hobby. My ER hangs on top of my power outlet box and the AD clock is already on the floor 😅

 

If you proceed, you may want to ask seller for preferred Talema transformer instead of Bingzi as they are variants with it.

 

Cheers.

 

Richard

 

PS: my uptone 1.2 lps is powering my coveted Bel Canto FM-1 tuner

I did. Another $33, only 230 VAC. But this is a unsealed transformer. You still recommend to use ?

Oops ... 230v if not applicable certainly not and if unsealed I have no experience with them. 

 

Save usd33 and stock then ?

 

Cheers.

But do you know if it’s a better option in general ? Just placed the order, but still $33 to be paid.  So maybe I shouldn’t add the Talema. 

[richard_crl032]

For me, I will err on paying usd33 for the Talema.

 

Read up on sealed and unsealed thst seems to be on maintenance and exposure to the elements which is not a concern here.

 

Copper is the expensive component and I have seen the varied type of copper being used to reduce cost, including recycled and mixed aluminium ones.

 

Cheers.

Sorry, my english isn’t perfect. Is this a yes or no ?

 

Edit, I think it mean something you would, just to be sure 😀

Thanks.
