10m optical cable worth doing?

[eniriop]

My Phantoms gold are on each side of my TV set. My DVD player and TV are hooked to the phantoms with an optical cable and my dialog seats on the other side of the room close to my router hooked to it with the short ethernet cable that came with the dialog.
That way I don't need a long optical cable and my connection is perfect. Besides people have reported problems (dropouts) when connecting an optical cable to the dialog rather than to the Phantom.
I found that the same record sounds better when played on a DVD player hooked with an optical cable to one of the phantoms than when streamed over spotify premium with high quality setting. 

I have also noticed that since the last  firmware upgrade, there is less much delay between the TV image and the sound when the TV is hooked to the Phantom by an optical cable. It is not bothering me any more.
