Which External Linear PSU Upgrade for my Router?

Fidelizer Audio Nikola LPS. I own their Airstream - used as an access point after my Nighthawk. I also have 3 of these - along with multiple tweaks for cleaning power.

A router puts a high demand on an LPS - especially for streaming movies and gaming. Be sure to get one that has a decent heatsink. Unlike a DDC or DAC which has a minimal load and barely gets above room temperature.

YesI got this started long ago ,call linear tube audio they have a great LPS 

retail $750 you just tell them the voltage. Their LPS can go up to 8 amps

 routers - modem combo are around 4 amps at most.

What is the goal in using a linear PSU as opposed to say, using a power conditioner?

I'm using the exact sbooster model as pointed out above on my router. Can't say I hear a difference, it was an extra power supply I had lying around is why I'm using it. Makes me feel better is all. 

I use this. It has 2 outputs if you need to power something else that's the same voltage. I got the premium version for the extra couple bucks.
