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 🙂

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 🙂
 

Thats art 🙂

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.

I actually had one of my all time favorite listening sessions this night. I have had my first cable choke for a while now (not optimized, just my first try without really knowing what i did...) but as you say Wijnand there is something so incredible pure about this. It really is like the DAC is now working as it is suppose to work. Pure joy with the music!
