I received
this LPS last week to power my modem. The seller was able to install a 2.1mm output jack upon my request because it's much easier to find or make DC cables for this plug type.
The 2.1mm jacks are rated to handle from 3 to 7 amps depending on the make. The modem draws approximately 1.5 amps and the router approximately 3 amps. The 2.1mm jacks should do just fine powering either one of those components.
The first day of listening was tough because the sound was way too dynamic through my computer system streaming via WiFi. The living room setup is connected directly to the router and it sounded much clearer with less edginess. I moved the LPS to power the WiFi router the following day
(Netgear AC1750, 2.1mm plug was used).
The overall sound seems to improve every day. @auxinput was absolutely right about LPSs having a break-in period.
At this point, the LPS now has 150 hours running and my living room system finally sounds the way it should. The
Ellam Flex 3W is projecting an improved 3D image forward, there's better separation of instruments, and the tonality is mesmerizing. I don't usually listen to latin jazz but that genre kept me glued to the sofa earlier today.
My computer system sounds dynamic with a wide open sound stage but I need more time to evaluate it. I've been spending most of my time in the living room listening.
Anyone who streams music needs to have an LPS for their router and modem. You may end up compensating elsewhere in your system for the dynamics and transparency that you otherwise would already have if you used LPSs in the first place.In fact, I'm thinking about changing a couple of resistors in the crossovers to attenuate the treble. This now seems necessary to balance out the newfound dynamic range.
