Thanks Paul, That is a really nice gesture. Let me think about it 🙂

[Wijnand]

Nice! Keep in mind that it could change after an amount of hours

[Wijnand]

I would say with noise suppression in all layers of the frequency spectrum that it must be there where the magic happens. But I still doubt the edges to build the bits in the data stream. Maybe good power supplies cause steep edges and cause noise because of that.

For you both if you PM me. I can built a device for you as well.

Thats art 🙂

I’m not always on fire, for the hobby, but I can’t stand things that I can’t understand and still want or need to know. So I ran a double job for the past few years. One a real job and two the ‘hobby’

You’re right, I’m not so convinced about higher end ethernet cables. I’m convinced that every cable sounds different and now I know that they all seem to cause or leave another type and / or amount of noise. Which actually causes the differences in sound. In my opinion higher end cables often cause a color change in the sound. This also was the case with the audioquest diamond.

Normal cables in the different CAT’s are enough for me.

About the ether regen I’m still very curious, but I always thought my Pink Faun streamer is a regenerator as well. Although I wouldn’t need the regen any longer, I’m still curious, who knows 🙂

I think that the core is suitable for 20 to 50 Mhz. The ferrite directly on the cable can do 100Mhz. So it’s additional. I have placed an order so I can build 5 more boxes. I also have ordered ferrite cable boxes. The cable that I have used is CAT5e SFTP. For cleaning the signal it would be better to use UTP, but it’s a choise. They both have their strong points.

Also in my situation there is already very much done to prevent noise from the powersections.

I will listen again tonight, but it’s so very clear that there’s only little to improve left 🙂

Many tanks to Tobias!

Thanks for helping me figure things out. The level is insane! The sound is so pure and analog now. Details are clearly more tight and have more space. Its music in its purest form 🙂

I’m probably just at 90% of understanding, but It seems I was way off track. The trouble is caused by the ethernet, but it happens on the DAC. I think the DAC crystal was slightly out of phase.

The netgear box is the box with the ferrite cores. Its position is the last section where it enters the streamer. The Pink Faun isolator is used to separate the ground systems of the house and the Audes transformer

[Wijnand]

When people talk about jitter. I never really understood it. I’m not sure if this was meant, but I think that we should think in datawords and not in bits. In my system the sound becomes darker when I put real high grade power supplies on all my network equipment. The better the power supplies the darker the sound became. I think that due to the power supplies the signal became a lot better, but noise that was not related to the power section should be canceled as well. The above thing with the ferrite cores (on the TX and RX pair of the ethernet cable) was not my own idea, but it seems to work really great.

Think about 8 glasses of water which stand for a byte. When there’s water in the glas it means 1. When the glass is empty this means 0. But what about when we have half filled glasses. These half glasses still fulfill the digital value ( so it’s bit perfect), but when you convert them to analog you will hear a different sound in comparison to the conversion of complete filled glasses. The higher the value in the byte the more effect it will have on the sound. Because the digital value of the byte will stand for the analog voltage. So when the DAC crystal can switch on its own terms not troubled by noise it will capture the complete data word. See it like this (picture) When the datawords are converted with a better phase than the music will sound less cropt.

When the lines are less steep it means there’s less high frequency (it’s crop into a smaller frequency range). It’s only a theory, but the sound is much better

Thanks, Tobias 🙂

[Wijnand]

I have built the Ferrite box and separated the RX and TX on their own core. This cause triple the effect of the cable solution.

[Wijnand]

Thanks Tobias for thinking with me!

You just have brought a new idea to test. I will put the PC on another ground system. A PC is always leaking to the ground indeed. I have measurements of that. It’s fed by the Audes transformer at the moment. When I put it on the normal powernet and connect it with an Lan isolator. The ground systems will be separated.

When I control Roon I always connect shortly to ethernet. While listening the control PC is not connected with the network.

[Wijnand]

Yes but also without the PC, a direct connection to the router causes the same problem. Same problem maybe as with the PC 🙂

Well now I have to get into the car. I’m visiting some audio friends in Germany

Have a nice weekend!

[Wijnand]

Yes, I know about that. I have used Euphony Stylus on the Pink Faun streamer and Roon Roon as well. Euphony was the best. Still probably due to the clocks. The CPU was running at 0.3% at only one core. Without the clocks it was 8% how do you figure 🙂

I think a computer normally makes many mistakes.
