Modem performance and modem selection.


How much does a modem impact sound performance when streaming high resolution music and or video via Ethernet connection?  If you believe the impact is important/noticeable, can you make a recommendation on your favoured modem? Thank you

Comment on Ethernet Cable directionality. Yes, I know what you’re thinking: Are you out of mind?

from AudioQuest page on Ethernet Cable (Diamond),

RJ/E Diamond prepared Cat 7 Ethernet cables use solid 100% Perfect-Surface Silver conductors, which completely eliminate strand interaction, one of the biggest sources of distortion in cables, for clearer, more dynamic and involving sound. Superior conductor metals minimize distortion by having fewer grain boundaries and less impurities (such as oxides) at those boundaries. Solid High-Density Polyethylene (PE) insulation helps maintain critical signal-pair geometry. Of course all AudioQuest Ethernet cables honor the directionality inherent in all analog and digital audio cables; arrows on the jackets indicate the direction (from source to destination) for the best audio performance.
Steakster, I would like to get your input on choosing the proper LPS for my setup.  What would be the best way to accomplish that?  Relaying all of my equipment and how it is setup will be cumbersome using this format.  Let me know what information is needed and I will be happy to supply that.....Thank you.
Geoffkait, I am not sure what prompted your comment on that specific cable...However, it just so happens that i do have/use AQ Diamond Ethernet cables.
I'm using an Uptone Audio JS-2 with both rails set at 12v to power the modem and router. I'm contemplating upgrading to a Mojo Audio Illuminati v3. 
Thank all of you for!input on this subject.  Based on a recommendation from Steakster,  I did some research on all of my wall wart power connections.  The idea was to find an LPS that would match up well to the wall wart power sources. Based on my research, I chose the Audioquest Niagara 1200 LPS.  That should arrive next week. Can’t wait to get it hooked up and listen!  Comments are still welcomed.  Again thank You.
