If you do these necessary things much more of your system will be toe tapping .
Ifyou are into digital the issue is not getting the basics right for example
you should have a modem router combo to start , the agood LPS power supply going to the router for these wall warts are $5 pieces of noise and digital from house to house brings noise ,fiber optic sucks the life outof music
you need a quality Ethernet switch Ansuz and others sell them around $2500 and up, and good Ethernet cables ,the one at the endpoint most important .
for $400 Sablon makes a verygood one for the money .for example. ,even witha goood dac until your address these weaknesses then you-will not get that vinyl type sound ,dac should be at least $4500 on up if you want true reference quality sound .I go to many audioget togethers and finally got the message ,no short cuts Allowed !!
