Ahhh, that explains the really funny review I saw of Amir with a HT processor or receiver complaining about the noise caused by using HDMI from a PC without understanding how bad a PC is for ground loops.
As helpful as Amir is, and he is a real engineer, there are some gaps.
I have no issues using PCs as music servers, but I use correctly designed isolated USB DACs and "decent" cables. All my system is plugged into the same power DC blocked and filtered power strip. No problems. HDMI on the other hand is a disaster and who ever designed the plug needs a dope-slap. Other than going to fiber transceivers, not sure how to fix HDMI issues.
There is much more to. It then that ,myself and many others in our audio club some are true electrical engineers. ,for. Example digital noise can travel house to house that is why I isolate the coaxial filter, plus the Ethernet the Ethernet hub I use has low noise regulators ,linear-power supply,as well. As A OCXOover controlled precision clock feeding the Ethernet cable , and put in a upto date Modem router combo ,I bought the Motorola 8702 which has docsis 3.1 which is much faster, bigger buffer , even the wifi for the tv is better , and having a Quality LPS power supply to the router a 12v 4+ amp is night and day better sounding then the garbage wall warts that come with the router ,I have -0 wall warts in my system
and quality Ethernet cables over $4500 the 2 Ethernet, and usb cables Ethernet switch and LPS , efore the dac and streamer .if you want great digital performance
to surpass turntables youhave to spend $$ with the same precision you give to any
high quality turntable arm and stylus leave no weak link in the chain ,
and with XLR if all components are truly balanced for each item then sonically it’s much more quiet. Transformer coupled. This too cost $$ to do it corrrectly.
