I found the jitterbug to work well from external harddrive to dac.

When you turn the dial up late in a party a low powered amp will clip and cook your speakers.
When you have a high powered and high ampere amp it will cook your ears.
Nice looking speaker.
Sub as I understand need to be Active to bring home the bass,otherwise the amp is working to hard.
Use preout of amp or speaker connectors to connect sub to system. Different subs,different connectors.
I use Tp-link. They work! Had problems with other brands with compatabity with some of my hardware.
Nowadays they all work but if I want to change them both router and wifi access point needs changing.
Never used ASUS but they are rock solid brand. My :2c: :2c:
