I want to replace the router/modem Comcast with a high quality for streaming

@KR4 I am not recommending in line extenders! I am recommending wifi extenders.

OP, yes streaming has come a long way. My streaming system sound quality is the same as my vinyl playback… and both are very very good and in my investment level are about the same cost.

+1, @fastfreight

Instead of purchasing mass produced modem/switch that is not designed specifically for audio streaming…keep your Comcast/Infinity and add a high quality switch that specifically design for audio to filter noise. Consider adding Network Acoustics Muon Pro Filter between your comcast/infinity modem and your streamer. I am using a Telegartner Gold Switch with LPS and haven’t felt the need to upgrade in over 3 years.

Hi @lalitk !  I have the Muon Pro filter just before my streamer.  I too love the M12 gold.  Adding the Switch X and keeping the M12 is the bomb!  

There may be other options but this thread is about modems.
