Here is my set up: PC running JRiver-ethernet cable 1-verizon fios router-ethernet cable 2-BuffaloTech NAS, and verizon fios router-ethernet cable 3-wall (in my study)-ethernet cable 4 (in the wall to the basement)-ethernet switch-ethernet cable 5 (in the wall to my music room)-wall (in the music room)-ethernet cable 6-Directstream DAC Junior.
Therefore, total 6 ethernet cables, 4 and 5 are long runs in the wall, not upgradable at the moment, assume that the builder used generic Cat5 cables, is this case, is it worth to try better ethernet cables for 1, 2, 3, and 6, since they add all together only accounting for a small portion of the ethernet signal path?
Another question for my education, what is the exact signal path in my setup? I use MConnect on my iPhone to control JRiver. After I press the play button on my iphone, what happens next in order for the 1/0s stored on my NAS to get to my from DSJ? maybe 1/0s on the NAS to the verizon fios router, to my pc, back to the router, and to the DSJ? One reason I asked this is, if not to replace all ethernet cables 1, 2, 3, and 6, if only replace two of them, where to put them in the chain potentially will make a difference?
Thanks for the advice.
