I have the exact same problem with Sony pha3 with active speakers but absolutely no noise with headphones I assume that it's because sony pha3 is originally made for headphone amp desktop powered + usb -> noise adapter powered + usb -> noise desktop powered + toslink -> noise adapter powered + toslink -> no noise notebook plugged -> noise notebook on battery -> no noise would balanced connection solve the problem? because both pha3 and my active speakers support balanced input output I could imagine my noise is what they call RFI and I think the noise very related to mouse, keyboard interactions and graphics card

is modded benchmark dac1(used) still worth buying? i have read great reviews on modded dac1's but they are all reviews of many years ago and they are not even being talked about as much these days i already have dac1 usb but after reading all those reviews on them, im kind of curious how far the improvement will be anyone with any experience with one of those? probably not nearly as good as say overdrive or constant(HS) though right?
