RPi3 B+ wifi and USB

ok so i have not been active for a while and stopped playing with my PI.

i have a question for those more knowledgable.

if i use my Pi3 with a large Micro SD card as storage for music files with Mo0de as the headless player over wifi will the USB ports suffer from the Ethernet problems when i plug my DAC in. i will only be using local storage via the Micro SD.

also, i personally dont see a problem with jitter from the usb if the dac has built in filters/clocks so i see no need for a top hat dac but please correct me if i'm wrong.
