Interesting observations.

What would be the IN and OUT dia of the new yellow core? Did you use in combination with the double core box? Or just the cable?

Yellow core is the same size as used in the larger size and to you better double core? Is it 6cm OD as Eric used by any chance?

 

Then maybe the MUON also has larger cores than its predecessor?

What is JCAT doing, where? I have a hard time visualizing the total picture.

I couldn’t resist 😉 , I made my first choke cable, very promising. I tried to share a picture with both of you but this site is really awkward and the most user unfriendly unfortunately (to me at least). No clue how to do that.

Cheers!

Wijnand, I would send you my EtherRegen anytime without hesitation so you can try. But there will be duties and taxes and expensive shipping coming from Canada. I know it’s me insisting but I wouldn’t be resisting if I can do without.  And I guess I hope it will help you find answers about the « half »  bits (with John Swenson you never know, he might be close to the answer).

The real challenge lies in identifying the common denominator among these setups. It’s about figuring out what elements in what configuration consistently contribute to better sound quality across different configurations. That’s where the real magic happens. Like the 8 windings possibly? I am out of time but I look forward to give it a try when I can.  Thanks for sharing.

Agreed it’s not common knowledge, but I think we really need to unpack how passive filtering works. There are so many variables at play, especially when it comes to those ferrite cores. Eric, NA, and now Wijnand each have their own methods, and they’re all seeing impressive results in their setups. ENO and MUON pro have caught the attention of quite a few audiophiles too.

Why stick with just single or double cores when we could experiment with triple, right?

And there’s a whole bunch to consider with the type of cores, their sizes, and thickness. Plus, the number of windings is crucial. Just one extra winding can completely change how frequencies are affected.

And what about those Cat5 cables? Do we wrap all the wires or just certain ones around the ferrite?

It seems like using a passive filter with a special isolated Cat5 cable just makes the sound quality even better.

And then where’s the best place to put that filter and cable combo?

<p style=”text-align: center;”>Hoi Wijnand, I was curious of course and it seemed you made big progress! I admire your perseverance, you are (always?) on fire! Also  a picture(s) is worth a thousend words, thanks!</p>
Thanks also to Tobias for your input. Do you know if the double ferrit cage, as built by Wijnand, is based on the Muon pro or the previous filter? In what does the Muon pro differ?
And what would be so special about the Network Acoustics noise rejecting cable design? I know Wijnand not to be convinced (any more) about higher end Ethernet cables but it seems NA and Eric (the sound of ethernet) found a beneficial synergy when using a passive filter WITH a special ethernet cable.
Wijnand, how much I wish you could replace the switch with a clocked and LPS powered EtherRegen to find a difference in SQ.

Thank you both for sharing!

I fully agree with points 1, 2, and 4, but I completely disagree with points 3, 5, and 7

Point 6 ;How about stating it as: “Rather than improving in mere hours, it’s expected to enhance over the course of days.”

Hi Wijnand, I located you here. I may return in the future. While I grasp your setup’s details and believe in them, my personal experience leaves me somewhat skeptical about the explanation. I’ve heard of users occasionally resetting the network, but typically on a monthly basis. I’ve never attempted it myself.

In the months ahead, I’ll be quite busy, but I wanted to share additional insights from John Swenson (found on AudiophileStyle) regarding networks and common misconceptions. These observations aim to delineate the various elements influencing perceived sound quality. I won’t provide explanations myself, but I hope these insights offer a deeper understanding. It’s worth noting that participants in the discussion prefer different solutions for optimal sound quality, ranging from fiber to Cat5e to WiFi. While there are diverse means to achieve similar results, each system and its connections are unique.

Quote from John Swenson @ AudiophileStyle:

(…) Digital audio networks seem to be “disturbed” by two different things, jitter on the data and common mode current on the wires. These are actually converted one to the other in many places in the network path. The end result of this is jitter on the clock and data in the DAC subtly changing the analog signal output from the DAC.

This has absolutely NOTHING, I repeat NOTHING to do with the data bits being corrupted, check sums etc. It has to do with subtle changes in timing of the data bits and small ground plane differences getting into the DAC through the normal network connections. The Data doesn’t get corrupted in any way, the bits are still the same.

There are some big misconceptions about optical network connections. The optical connections do NOT make the timing perfect. They do NOT “reclock” the data. whatever jitter that is on the input is still there on the output, in fact the electrical to optical and back to electrical ADDS jitter to the signal. All higher quality optical equipment can do is add less jitter to what is already there, it CANNOT reduce it. What is beneficial is that it completely blocks the common mode noise including leakage currents from power supplies.  It  blocks one of the issues but makes the other slightly worse. All higher quality optical equipment can do is make that “slightly less” even less, but it is still there.(…)

Hi,

I wrote a reply 4 times , but when I paste a link everything dissappears. Sorry I give up.
