Do different routers affect sound quality

I have a simple question about network routers. I have been running a small laptop (Toshiba) thru a USB Regen to  my Ayon CD5s. The files have been stored on a WD Remote Hard Drive and connected directly to the Laptop via ethernet cable. I just recently received my OPPO 205 and have connected it to a verizon router as well as the WD hard drive.  I know there are high end ethernet cables out there but I never hear anyone mention the Routers. It would seem where the signal is going thru the Router that this would have and could have an impact on sound quality. Has anyone explored using different Routers and are there any suggestions? Which do you think is a better path USB from Laptop or Remote HD thru network Router  connected  to the OPPO?
