DIGITAL NOISE

[♔Chello]

Thanks Chello! I'll try moving my PC, it's now next to the mixer and studio monitors.
Which brand USB-isolators did you order? On the internet I see different brands, cheap and expensive ones. Maybe the cheap isolators work perfectly in my setting.
I'm excited to see what your results are.

Moving the PC is usually enough - test if there is any audible change.

I ordered these:

   


I have now tested, and was shocked by the result:
I use an AUNE S6 DAC, which provides 32 bit/384 kB resolution with Windows, and 64 bit/Float with Mac.
But the isolator only allowed 16 bit/96 kB resolution; so what's the point then..?
And the noise was unchanged.

I also had a real nightmare finding a new driver for the DAC, because the Windows driver crashed.
So tested USB Isolator is completely useless.


On the other hand, I have long used TOPPING HS02 USB ISOLATOR for the Aune DAC, which costs about 100€.

This works well and can be recommended, but remember to turn it the right way, otherwise it will bang !
Follow the manual precisely, and there is no risk.

The Topping isolator was unable to drive my previous MOTU M4 sound card, probably because this is USC C based and requires too much power.
