Yes, it's my photo of my unit.

 

Would you mind posting where you bought it, if that's not against the rules...

[Ponkbutler]

Thanks. Yes: you may have been lucky. There's no indication of whether it is 50 or 75 Ohm either...

@LowMidHigh Sorry I dont buy this.

You need to be careful with your views.

I live in HK and if anything, there is a strong bias towards European things....(which is definitely changing), if anything else. Which to me is based on an individual preference, driven by analytical analysis of sound (Using the instruments on the sides of ones head) and not necessary objective inference based on a  test data's....

To push the whole of Asia off the map with a swathe of your 'Non Prejudicial' statement is alarming.

 

Neither do I, from the UK. Many techies worldwide are into the bigger and better whether or not it has an impact on sound quality or quality of life. It has nothing to do with location, politics or race. It's just sadly human....

Is that the new one with 2x75 Ohm square wave outputs?

[Ponkbutler]

It's a pity PPA don't provide any phase noise measurements

[Ponkbutler]

I think we're discussing more than one. I was referring to the Paul Pang Audio (PPA) one.

[Ponkbutler]

Well, if we're seriously evaluating a group buy, maybe we should include the Mutec Ref-10 and Ref-10 SE in the mix? The only disadvantage they have is box size. They were designed from the ground up to deliver a low-phase noise square wave reference.

I bought Mutec Ref 10 before I purchased ER, with or without Ref 10 does a major impact in my system.

 

Have been listening for few months and ordered a Mutec Ref 10 SE120 for my listening room, it arrived this morning and have a listen for few hours so far, the improvement over Ref 10 is quite significant (subjectively 20-25% better)

 

My setup - Mac Pro > Cisco 2960 > SPF > ER (with SE 120) > UltraRendu > Esoteric K05x (with SE 120)

That’s very interesting, thanks.

 

Have you evaluated the impact of the two Ref-10s on the EtherRegen only? If so what were your impressions?

[Ponkbutler]

I look forward to hearing how you found the different clocks changed things, Renan.

[Ponkbutler]

Thanks Andreas (and Adrian),

 

Tha sounds very interesting. Will there also be an option for the OCXO Master Clock without linear PSU - I have spare outlet on my Sean Jacobs linear PSU.....

Hi Guys,

Just ordered the Giesemann Master Clock with Emperor Crown OXCO with seems  superior to entry level of Cybershaft.

Including an appropriate Supply LPS ( Carbon Fiber, Gold fuse, Furatech NCF and 0,8 mtr DC cable)  with all further add-ons Clock Cable (Huber + Suhner & BNC plugs)  and Cybershaft 75-> 50 Ohm adaptor.   AND A NICE GROUPS BUY DISCOUNT FOR " AUDIOPHILESTYLE"  USERS.

 

I give the Giesemann a fair chance. Ps. I also ordered the BG7TBL 10Mhz Ocxo 3 Channel Square Wave for around € 90.00. And I can compare everything with a Mutec Ref 10 and maybe a SOTM too.

 

That sounds very exciting and your impressions will I am sure be helpful to many of us.

In any case I see a need for a clock with isolated outputs or several clocks. Minimum 2, possible 3 outputs. Square wave. 

Doesn’t that describe the Mutec Ref-10 and SE clocks? Or are their outputs not isolated?

[Ponkbutler]

I use two daisychained ERs with a nice but not immense benefit. The first, which has two A-side connections, is powered by an earthed output from a LPS while the second is not earthed, only having one A-side connection.

Several has used the Cisco 2960

FWIW my system sounded better with the Cisco removed. Others have found the same thing. It could be system-dependant 

[Ponkbutler]

I think we could speculate endlessly on this when in the end - as audiophile consumers - it's really just a matter of what offers the best compromise or ultimate performance here and now, or what we criteria we set to determine how long to wait before pulling the trigger.

 

FWIW an acquaintance uses a SOtM Master Clock on his ERs (so sine not square wave output) and is very pleased with the result...

Dear Alex and John,

 

How long do we have wait?  It seems a promise that is now constantly being postponed. 
May be we should call it “ Brown papers Master Clock EtherRegen” .

I can fully understand your impatience, but I really don’t think that tone is called for.

 

After all this is more than anything else a favour to all of us in the “Uptone community” and we all know this is a period when both John and Alex have their hands full.…

OCXO:MV89A manufactured in 2009.(USED)

 

And quite transparent about it. Moreover, from the pic at least, the OCXO is a Morion

NO.  We are still waiting for the clock papers by Uptone & Swenson company.  Repeatedly stating ...before buying clock products, please wait for the clock paper to come out.......to make an informed choice!

 

In the Audio industry like Merging Nadac also Master Clocks brands Mutec, Tascam, Antelope .....all use a Sin Wave 50 Ohm and less 75 Ohm (mostly for video) in their studios and consumer applications.

 

John was quite clear about square wave being preferable and has not given any indication that the clock paper will mark a change of thinking.

 

You keep repeating the above-quoted misinformation about clocks. The Mutec Ref10 is, for example, a square wave clock with a combination of outputs, but gives the preference to 75 Ohm, as you can see from the number of outputs provided:

• 2 x 10 MHz reference clock BNC output, 50 Ω terminated, unbalanced
• 6 x 10 MHz reference clock BNC output, 75 Ω terminated, unbalanced

 

As you report different types of good external clocks result in an improvement. We have several reports of this on the forum and I have a friend who is very happy with adding a SOtM clock (sine wave and 75 Hz) to his EtherRegen. But of course no-one wants just better, we want best 😀

 

Also, note that whereas the SOtM clock was originally supplied with only a 50 Ohm output, they now offer both 50 and 75.
