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

Here's are some links to the products I bought on Amazon.

Media Converter with Transceivers

Fiber Optic Cord

It can be a bit confusing with the terminology (MultiMode Dual LC Fiber, etc.)

@pindac Correct. So from your central model to your primary router you would have the single run. Then split off from there to another router. Each router either dedicated to wi-fi & data and the other to streaming/hi-fi duties. The other thing is that my wife works from home and having a separate wi-fi network for the data usage means less lag when I want to stream music since it's on its own network. 

Time Warner was nearly the death of me and then we moved and Comcast was worse.

A somewhat germain remark to add here...I heard a while back ago that Time Warner, Comcast, Verizon, etc. had a lower approval rating than congress. That still true?  

Hello Fastfreight,

Regarding your Verizon Fios G-3100 router, I had difficulty matching the barrel size of the DC cable from LPS that I tried to power the router with. Seemed like DC plug was closest to 2.8mm but not exactly. Do you know what size barrel the plug is? I may try the LPS again. 

Based on my experience what worked for me has been:

1. Put audiophile grade network switch in front of your streamer - I use LHY8

2. Put the best network cable between the audiophile switch and streamer - I use Revelation Audio Labs cable. totally awesome cable, imo

3. Use very good power cords for both the streamer / switch and feed good electricity

4. use non-audiophile grade switches to avoid using a long ethernet cables. by doing this, it lowers noise I found. 

5. If you had something like Synergistic Research Pod, put it on top of non-audiophile switch. It smooths the sound. I use one and it has made definitive improvement
