So I have this issue whenever I play games with my PC where suddenly my speakers start to crackle (not super loud just a little kind of like a slightly louder hiss) as soon as the game starts to render (so from a general observation, it seems like when I put the GPU into some actual use). I"m using a RME ADI-2 DAC via USB and connected via RCA cables to a Nuforce STA 200 (This was when their was no published Amir dimensions ) and from their it goes into a pair of ATC SCM 7 V3. All of the outlets are plugged into one power strip.Was wondering what could possibly be at fault; could it be the amplifier? or something else? Could getting an amplifier that takes balanced inputs possibly solve this issue? On a side note, stereo amplifiers are pretty expensive when you want >80 Watts.

Sounds like PC noise is bleeding through using the ground wire. Do you have a headphone you can check with RME"s output to see if it is there too?

Just tested my Campfire Andromeda with the IEM port on the ADI-2 DAC, 0 hiss when playing any game (Hitman 2 in this case). Also have the THX AAA 789 connected via balanced cables and their is no hiss or crackle on that either with the HD 800. But when I go through the speakers, suddenly the crackle occurs. A bit vexxing to say the least!

Definitely noise leaking through the ground to the amp. I have one of these ifi iDefender 3.0 to review which is supposed to break the ground connection. Here is a too long video testimonial about it (play at 1.5x speed):

$49 for the price of my sanity might be worth it. Thanks for the help! Also was wondering if I had a balanced input stereo amplifier (Looking at NAD C268), would that do anything?

Got the iFi Defender 3.0 in and while it helped eliminate the speaker buzz when playing games, it introduced it"s own noise into the system. It was much lower than the speaker buzz during games, but now when the GPU is not under load, their is an additional noise in the background (more high pitched) . Probably going to return it and see about getting a stereo power amplifier with balanced inputs. Also I have isolated that it indeed is the ground noise that is passed through the USB cable. Heard the Schiit Eitr galvanically isolates but not sure if I want to go that route and its a lot more expensive.Thanks for the help so far amirm!
Wow, that is pretty useful feedback! The dongle may be removing the ground connection altogether causing other problems.
