I bought the stardard version intona and fit it between my HPTC and USB interface. But i found one issue that the "output" of intona cannot be compatible with my Wireworld Platinum Starlight usb cable which means the windows can not recognize my usb interface if I conect Intona to my usb interface with the wireworld platinum usb cable. Same happend to my QED usb cable. If I use the generic usb calbe between Intona and interface, everything is ok. So, in my setup the only way to make intona working is to use generic usb calbe or A/B adaptor after it.
My setup now is like this: HTPC(HQplayer@win10)>Wireworld Platinum Starlight>Intona usb isolator>usb A/B adaptor>Audio-GD DI-2014>HDMI Cable>Audio-GD Master 7> Audio-GD Master 9> T1
With Intona Isolator, the sound does is improved....It is worthy...
