@nyev just looked at your system pictures…couple of things you can try, if I may suggest…
1. Raise your cables off the floor. Cable elevators are not expensive. AQ makes decent ones called fog lifters. Lifting the speaker cables, interconnects and power cables off the floor in my system makes an audible difference.
2. try to position your signal cables as far away from power cables as possible or at least don’t lay them down close to one another in parallel - create a 90 degree angle and it should be ok
3. your amplifier is too close to your streaming components. The power supply can be creating an EMI there. I would move the Innuos stuff away from it about a foot at least if possible. I’ve found, in my system with all the amps I ever had that the system sounded its best with the amp on the floor or amp stand and as far away from source components as possible . This will probably minimize the noise your speaker cables may be picking up from the streamer / network components ascwell.
Again, just a thought and is cheap or even free to try.
