Wyred 4 Sound W4S DAC-2 DSD

Hi there,

I am running a music server off of a headless PC. (No monitor.)

It is running Daphile, a Linux-based single purpose music server based on Logitech Media Server.

My Wyred4Sound DAC-2 DSD is connected to one of the PC USB ports via USB cable. Other than the power cable, there is nothing else plugged into the PC. No other USB devices, cables, etc.

My question is how does the USB input of the DSD-2 DSD compare to the coax input?

I have heard that previous W4S DACs (non DSD) may have benefited from the Audiophilleo or other similar USB to S/PDIF devices. However, the USB on the DAC-2 is upgraded, has galvanic isolation, supports integer / direct modes, requires no drivers on Mac / Linux, etc.

Would I benefit from getting an Audiophilleo, connecting that to the USB of the PC, and connecting to the DAC via coax? Obviously, I would lose DSD capabilities this way.

Is the USB on the W4S DAC-2 DSD elevated to the point that a USB to S/PDIF convertor would not provide improved sound?

Thanks,

Mark
