Hey!

 

Ive just bought a Taga Harmony HTA-700B SE hybrid tube amp and DAC. It connects to the pc via usb and gets the power from a power cable (230v).

 

The problem is that I can hear the cpu when its under load (gaming). Since its a DAC too I dont really understand it.

 

Any possible solutions?

Are you sure it's not the graphics card you're hearing? Regardless, try disconnecting the USB cable and see if you still hear the noise.

If I disconnect the usb the noise is gone. I tried with a different cable too in all usb slots and still could hear the noise.

Okay, so at least we've identified where the noise is coming from and eliminated a few other possibilities. The next step would probably be to try a powered USB hub or even an isolator like the Schiit Wyrd. The latter will be pricey, but more likely to make a difference.

Or I just send it back to the local shop and get back the money within 3 days
