LPSU foe modem and router - how important?

I bought a reasonable priced PSU off allied express...just to eliminate any doubt...I am happy with my purchase...I have the latest  Google fibre router and it uses two power supplys...but got what I needed in one box with two different voltages. I am happy. Took the doubt out of my mind for less than $200.

Yea, most of use have heard that the LPS is always better then using a SMPS.  I have a Bluesound Node N130 and I bought a LPS for it.  It did make a difference, not a $400 difference, but a difference.  The biggest BUT is that you have to bypass the SMPS and that will void your warranty.  On more thought is, SMPS’s have come a long way, so you might look into getting a better quality PS that you can plug into the same power socket.

All the best.

It is completely dependent on your streamer. The better your streamer, the less it matters. 

Good Morning @ghdprentice !  It may matter less, but but I hear the improvement. Obviously there are folks here that don't hear it, or don't want to try it.  And to others, there is just plain 'good enough'.  I know you are neither! 

 @mikhailark, you might be best suited for the world of Docusign and military concerns vs. the nirvana of amazing sound.  But I am glad these discussions cause you to laugh.

Very important I have linear tube audio on the router tons more noise filtering 

over 100 k in capacitance and worlds best Belleson low noise regulator,

for the Ethernet hub  LHY make decent ones and there top model is exceptional 

at $2200 the cheaper models around $800 ,$25 hubs are junk and add lots of noise to the end point ,and at minimum a Pangea $200 power cord Everything counts in Audio !! P.s Ethernet cables ,nothing under $2-300 from router , end point most important $1-2k
