Of course it’s a computer. What’s your point? It’s specifically designed for the job to be low noise in every way. It’s most definitely not a PC or a laptop or a MacBook.
I used a Bryson BDP-4 with 3 alimentation and 2 USB BUS. For 5000 Euros.
It is a good computer With the Linux OS.
But the ethernet noise go to the 220V and kill the Dave.
The Bryson has a SSD drive.
The first time that the user stream a song, the song is stores on this SSD.
The second time, the user play the song, the Bryston read the files on the SSD and the ethernet is not used.
The difference between, the first and second reading is audible.
So for me, the price is not enough and the goal of the constructor to send a good usb signal could be perfect but if the streamer send noise to the 220V,
a power cable for 1000 euros will conduct the noise perfectly to the Dave and kill the quality.
If you place ferrites and filter on the 220V cables and you can not detect a difference then you will make the demonstration that the low noise is in every way.
Actually, I have an Aurender N100H designed to be perfect with usb 2 bus. With the Aurender optical convertor, it is better than usb. So the audio usb bus is not perfect.
But It send always noise to 220V.
I place a Wifi bridge ( on power bank) to remove the Ethernet noise from the RJ45 cable of the rooter but it is not enough.
To use with the Hugo2, this setup is perfect but with the Dave, the noise is audible.
My best solution about noise for Dave and HMS is the 2Go 2YU. With the 2YU, the BNC signal is as good that the optical one.
The 192kHz optical of the 2YU works sometimes. I had never tried the port USB.
I would like to have a good PC but i am tired to loose my time in research and test of a good one.
