LPS for Verizon Fios Router


I want to use LPS on my Verizon Fios Router.  The stock 2.5mm DC cable is too large so bought a 2.1mm and still too large.  Does anyone know the DC cable size?

Had Sbooster in system for 4+ days now.  It removes edgy/brittle with a more analog liquid sound.   Nice upgrade!
Where did you end up getting it?
Acoustics Sounds.  Hi-Fi Heaven also has 1 in stock as of last Thurs.   No brainer if streaming music through the router.
