But it is, unfortunately, still quite a strong noise. In addition, when using an analog source with ground, you reproducibly generates a rather annoying ground loop. This is actually the extent that you want to use any analog input, because the music to my ears is no longer fit for human consumption, particularly in quiet passages.
Even if one picks up the sound via USB, and an RCA cable is still connected to the amplifier, there is this ground loop. Only a galvanic separation filter of Oehlbach brought Remedy. However, it is not acceptable that one again has to invest 50 to use the product as it should be.
There remains only the excessive noise. I have also written this regard the vicious support, but there will not get any response in two weeks, weak. I did not expect in this form.
My conclusion:
Wers would like to use with USB, is super served, but who due to a high-quality sound card also gladly wants to use its analog outputs, you should look around for alternatives.
