Hi, I finally bought a little Dot MK2 for my HD650 and a Topping D10s as a DAC. My problem now is that when I turn it up to over ~20% I can hear a buzzing that get's louder the higher I go. The buzzing stops when I disconnect the RCA cable from either DAC or Amp even when the little Dot is turned to the max. Does that mean that the signal coming from the DAC is the problem?

I'm guessing I should get a DAC with a power source that is not the USB connection. If you think that is my problem what DAC would you recommend for around 150€ or less (more only if absolutely necessary).

And while I'm at it, would an optical cable be better than USB?

Thanks for your help, I really appreciate it.
