Reducing hissing noise in desktop audio ?

post #1 of 4
Thread Starter 
Hi folks,

is there any way to reduce the hissing noise in my Windows 8.1 workstation audio setup ?

Laptop ---USB 2.0 cable---> USB docking station----TOS Link Fibre optics---> DAC ---VanDen Hul interconnect cables----> AMP---->Westone W4R (stock cable).

I'm using it as per my signature below, with everything plugged in to the power conditioner, but somehow it doesn't help, when I turn the volume up from the Amp, the noise also increase accordingly.

i have use belkin power Surge protector board in all of those equipment, but somehow it is still giving me that noise.

Any help would be greatly appreciated.

Thanks.

Always hard to find the source.

You can try to unplug in a systematic way PSU of the laptop, USB cable, Toslink, etc.

 

Might be a ground loop.

Good luck

W4r's are very sensitive and have an output z of only 31 ohms iirc, I'm wondering if an impedance increasing adaptor might tame the hiss.

Yes, you guys probably correct,

Because with my HifiMan HE-500 head phone, I couldn't hear the hiss noise.
