What i meant is that using another unused bnc is not griunded directly with the next bnc output which the cable is connected to.

 

Each bnc is isolated from each other.

 

So meanimg not a true or best ground...

 

I think you're missing the point of how cable shielding works.  The fact that signal and grounding cables are connected to separate, isolated outputs is irrelevant.  The "signal" is being grounded, not the chassis.  The REF 10 itself is properly grounded.  Based on my experience chassis grounding properly designed linear power supplies, as long as you're not experiencing ground loops, a chassis ground is likely to provide little to no audible benefit .

Please note that I am not arguing about Mutec good performances. But for several reasons, like the ones mentioned by @mansr, we should rather compare phase noise at DAC's output where it may matter. 

The advice is coming from somebody used to deal with phase noise and synchronization in Telecom industry. Feel free to delete.

 

I am not touching this. This is the same discussion that derails hundreds of threads here on AS.

 

It's up to OP @Octagon to decide the scope of this thread. If so, he can so state, and even request moderation privileges from @The Computer Audiophile if he likes.

Hi Mark S

 

I am using a "half stack" - a Vivaldi dac and clock with a Mutec REF10 with Habst BNC.

 

First I was very happy when upgrading my Vivaldi dac with the Vivaldi clock. But it was when adding a REF10 it got really interesting. As I recall I thought the REF10 upgrade was much better than first adding the Vivaldi clock on its own. When Habst BNC cables where used compared to generic BNC it added a sense of focus, calmnes and better dynamics which connects me closer to the music.

 

Next step for me in january will be to upgrade my REF10 to REF10 SE-120 with -120 dBc/Hz😃.

 

Happy holidays!

 


i’m in for the upgraded unit. Seems intriguing. 
 

i’ve also emailed Habst about the bnc clock cables. I wonder how the Habst compare to the Nordost V2 cables I’m using for word clocking???

Has Mutec made an official announcement about an upgrade path, or even officially announced the REF 10 SE-120 is available for purchase?

Hi auricgoldfinger and @LowMidHigh

 

I have not seen any announcement from Mutec but as I read about the SE-120 in here and WBF, I sent a mail to Mutec and was able to reserve one of the oscillators they had incoming. Very happy for this as I understand there is a very small numbers available right now.

As an aside, but relevant to some of the Mutec related questions that have been posted over the last few pages, I notice that the formally very active and helpful on this forum @julian.david has not been seen here, and indeed has not even logged in, for just over one year now.

 

A shame, because in the past he made an extremely useful contribution to this forum.  Does anyone know why this might be?

Mark,

 

One of the key metrics to look at is the published phase noise @1Hz offset at 10MHz. The lower this number, the higher the quality of the clock. This is a gross simplification, but as a first pass it’s a good metric.

 

The Ref 10 is -116 dBc/Hz. This clock seems to be -110. That’s quite a gulf in favor of the Mutec. 

Hi Rajiv,

May I know what's the reading for the soTm Master clock? I cannot find the numbers sir. Thank you so much.

Will you be getting a brand new unit or sending yours to Mutec for an oscillator and case upgrade?

Can you share the uncharge?

it’s on the product page: https://www.sotm-audio.com/sotmwp/english/portfolio-item/sclk-ocx10/#toggle-id-1

 

They don’t appear to publish their phase noise at 1 Hz offset. You can compare the rest with the Ref 10.

Holy crap, just got a quote from Mutec for upgrading from REF10 to REF10 SE-120 >>> €2,400 !!

What exactly do you get for €2,400?  Does this include a new case in addition to the improved clock?  Any other internal changes?

I presume the case is the same, since I have seen a picture of the SE-120. Regarding other internal changes beyond the clock, I have no idea... I subsequently asked for the retail price of the SE-120 version to have an idea whether the upgrade is worthwhile (ie. is the price of the REF10 (€3,500) plus the upgrade (€2,400) less than the price of a new REF10 SE-120. I'm awaiting an answer from Mutec.

Does it actually gives a discernable bump? Back in the day, both Mutec and the Japanese enterprise swore anything below - 116 makes no difference....

The SE-120 case is different.  It has a grounding post on the back for people who want to earth ground the case.
