I found DLNA to be better than asynch USB. Here's my recommendation
1) make sure your audio connectivity is hardwired Ethernet, not wireless between PC as digital media controller, any NAS and the Denon as digital media renderer... it matters
2) follow the PC optimization recommendations for your OS on the computer audiophile web site
Assuming the Denon has a competent DLNA implementation you should be very happy with this. If you try to go wifi, un-optimized be prepared for mediocre sound... superfluous multitasking on the PC and wifi signal strength fluctuation causes marked loss of fidelity
