Pretty sure there is another thread similar to this already running - assuming you have good quality interconnects that mate well with your amp/preamp I would look at upgrading the Ethernet cable running to your Node 2i.
I found that upgrading the power cable was hardly any better if at all but moving to thicker gauge and better shielded CAT8 cable made an appreciable difference in my system.
Adding a good quality network switch would be the other thing I'd look at - in other words start with your Modem and work your way to the Node first then worry about the rest.
