Master Clock for your EtherREGEN

the Canare LV-77S features the lowest attenuation for a stranded core. However, both manufacturers catalogs solid-core products with considerably better performance.

 

Could you mention some of those?  I'm assuming these aren't available pre-terminated and can only be found on very large spools.

Belden 4694 for example. (I'm waiting for some data from Canare regarding thier HD cables)

 

According to John, a flatter the curve the better. What I did was to calculate the slopes between the sample points provided by the manufacturers and compare. (Y2 - Y1) / (X2 - Y2).

 

Belden published more points, but they don't exactly overlap Canare's. I did compensate with any extrapolation, rather did my best to lay them as close as possible.

 

The resultant figures are in radii and multiplied by 100 to assist the eye in discerning the differences. 

 

See attached spreadsheet. 

 

As you can view in the spread, the 77S has flatter slopes than the other stranded cables (Furutech slopes are abysmal). Belden beats it by a nice margine.

Blue Jeans Cable has 4694R for 12G terminated with Belden bnc:  https://www.bluejeanscable.com/store/sdi-cables/index.htm     About $18 per foot.  

 

Do you find that the clock cables you use took a long while to settle in/burn in?

Both my Canare LV-77S and Belden 4694R took a little while to burn in. Both are available terminated by a few vendors on eBay.

I can’t answer it in good faith, as I find it difficult to isolate the contribution of cable burning to my system—if is such a phenomenon exists at all.

 

I have multiple devices connected to my ref clock. When I add another one, it takes a bit time for the new device to settle in, and when it finally stabilizes, it becomes part of a rather complex environment, in which minute changes in cable performance due to further “burning” are difficult to detect. Mind you, even temperature and humidity fluctuations impact your system, so now go and hunt down the effects of one specific cable 😄

Alex had mentioned that shielding is the important quality for sine wave clocks.  These work well for you so I assume they are well shielded.  Seems I've seen double and triple shielded cables too...

@Superdad indicated that the quality of the cable was important for a square wave. Not for a sine wave with the filter for example.

On the other hand, the posts do not have much to do with the master Clock.
It would be a good idea to create a specific topic. this is just my basic consumer opinion.

Otherwise it's quite funny all these measures because it is forgotten the musical listening

Yeah, definitely takes the cup. Some stiff stuff though.

I find inexpensive experiments fun.  This one would be $33 (the far greater cost would be the time of break in, which I increasingly dislike).  Less than the cost of the filter experiment and may yield no result, but only to satisfy curiosity.  Increasing the pleasure of listening to music is my only goal.  We all get to audio nirvana in different ways.  Those different ways are interesting to read and learn about.   And, it seems, there are no shortcuts.  

 

I agree we audiophiles are subject to the latest fad and that these thread meander off topic, but you sometimes find a gem that increases your appreciation for music.

hi ,

I see you are using Wireworld starlight RJ45 cables like me.
Did you measure the impact on the ground loop that these cables can produce and break the B side of the etherregen because some say that this type of cable is "bad" although it is called audiophile.
I would like to have your specialist opinion?

Laurent

Laurent, 

 

Where did you hear Wireworld Starlight Ethernet cables impact the ground loop and break the B side of the EtherRegen?  I have the Wireworld Platinum Starlight 8 Twinax in my system (3 x 2m cables) and EtherRegen in my stereotimes reviewing system and I have not experienced this cable to break the B side of the EtherRegen or create a ground loop.  Just wondering the source of this....

My Wireworld Starlight ethernet does not break the B side" because I prefer the sound with this cable than the cable bought from ghenaudio JSSG360.

there is certainly the theory but I prefer my feeling to the listening and it is impossible for me to measure if there is a ground loop or that the B side is broken etc.
Enjoy your music with your cable.:)

I have this same Wireworld cable and do recall seeing Alex posting some time back that cables with exposed metal plugs were not good to use but still prefer it and have continued to use it as well.

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

are metal plugs bad?

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

That’s very easy. Just ohm the connectors.

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.

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

I don't care about "standards" - I just care if it sounds good.

AudioQuest Vodka is good for Side B etherregen ? why ?

because the outer jacket of the vodka is only connected to the receiving end

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.

I haven't found much of a difference on the A (incoming) side and therefore use flexible cables with plastic connectors, but the cable made a difference on the B side (out to DAC).   Many folks like the Blue Jeans cable, but it never sounded good in my system.  Strangely, even copper ethernet takes time to settle in/burn in, so rapid A/B test may not work well.

I agree, but @AfterDark. asked me not to post pictures of the inside out of concern for his designs being copied.
