Even USB need proper breakin I use roughly 300 hours and I. Have used several
cables well over $500. The top cables use better materials ,better shielding,
and power legg is totally isolated. That being said there are many other factors
like myself I have a completely isolated usb board and all SS drives , filtering to the power supplies , which make a Huge improvement
Jplay sell thevery good usb boards, as well as Ethernet dedicated boards , that are 1000 times more quiet and isolated then stock computer boards , your music sounds much more pure and natural sounding , it is equal to or better then a more expensive dac upgrade.
then with a standard board from your graphics card . I also added Noktua
best heat pipe for the computer processor . I have just one big very quiet
Noktua side fan. All these things add up to a very good sounding digital setup.
and yes power cords and a dedicated line, copper outlets , and line conditioning
all count .make your own server and saves a Lot of $$.
