I'm a bit unclear as to why you want to upgrade your router. I have so many questions.
1. Is your computer a desktop or a laptop?
2. If it's a laptop, is it plugged into the wall or running on battery when you're playing music?
3. If the computer running on WiFi or Ethernet?
4. Are you having drops in your WiFi (or Ethernet) signals?
5. Or were you wondering if upgrading the router would improve the sound quality?
If you're running your desktop/laptop on WiFi, upgrading the router won't improve sound quality. But it might improve signal stability. Most people don't know they have bad wifi. Because even when they do, they stream Netflix at 480p resolution and never realized they're not watching 4K. Moreover, most devices have caches for unstable WiFi so unless you're streaming music and there are drops, most people don't realize their WiFi is bad. Basically, if you're streaming anything and it doesn't start instantaneously, your wifi is probably bad. If the problem is bad WiFi, the optimal solution is not to immediately buy a new WiFi router but to figure out why there is a WiFI stability problem in the first place and then decide whether to buy one of the routers you listed or to buy a WiFI Mesh Network.
If your computer is wired via Ethernet, sometimes, the ground loop leakage current noise can go from your router's power supply through to the ethernet cable into your battery-powered laptop into your DAC (which doesn't run on batteries, hence the ground loop), affecting the sound quality. One solution to that problem is to buy a linear power supply for the router (e.g. HDPlex 300W). But if you run your laptop with the charger or run a desktop, then you can still have other ground loop leakage current noise going from your desktop to your DAC, independent of the router. That's why people buy audiophile grade network switches, e.g. Uptone EtherRegen.
