Hello If using the pulse mini, for sure upgrade to get the linear power supply
a no brainer sounds much better still and use good quality after market power cords . Thungs left out but essential , most router- modem combos are 12 v just look on them or bottom or router , the wall wart is Horribly noisy
on Audiogon Linear Tube Audio - exceptional LPS power supply $50 off $700 use a decent power cord ,the $200 Pangea sig mk2 awg14 is a excellent low cost power cord ,I even use the synergistic purple fuse 20 mm 5 amp ,slow blow fuse
all these little things add up. Wall warts for any gear is an Audio sin they are noise and grunge .
is a great upgrade , I even upgraded the router modem combo to a Motorola 8702
that has docsis 3.1meaning much faster processor, and much bigger buffer
it works great, even streaming WiFi with TV better picture, and is 12v around 4 amps , the LTA LPS goes up to 8 amp , and can be ordered up to 19 v.
