Linear power supply for a router

I always over spec my lps,less stressed, greater reliability. I'd get lps that could supply at least 7amp, even more is better. This will be powered 24/7 so don't cheap out.

I use lps on my router, worth it for me to the point adding audiophile switch resulted in inferior sq.

As long as there is enough amperage to power the device you're fine.

Sorry, I miscalculated the amps. It's 5.26A. (the linear power supply is 100W)

As you describe it, it should be fine.

Presumably you want to stream music? I'd be curious to know if the PS change affects the sound
