Is there a way to add the level of protection against the usb ground loop ?

Hi,

Is there a way to add the level of protection against the usb ground loop and the transparent behavior regardless of the external power supply in your measurements for each DAC ?

Edit :
Because some DACs have good sound but bad USB isolation, and others a medium sound but a very good imunity against USB noise and bad insulation. I am looking for a DAC that manages a medium power supply and is very well immunized against USB noises and USB mass feedback

Regards,

Olivier

Don't want to shill but I had quite a severe USB ground loop with my Topping DX7S via usb and my stax energiser. I purchased the IFI Idefender 3.0 which reduced it greatly and then connecting a separate 5v power supply to it completely killed it.
