help choosing cable pc to dac.


I would like to stream audio from windows 10 pc.I am concerned with the limitations of the pc source.How far should I go up the cable chain ? 18ft run of 3.5mm to rca to dac.I want a good signal without added noise but don't want to waste money either.Can anyone share their experience or make recommendations.?RW

I use a USB?SPDIF converter with older DACs. The V-link, as suggested by markomaras, can be had inexpensively.  What will you be streaming in way of file type?
I get little tuner reseption where i live.Just want variety while working around the house, cooking etc.  pc has Realtech High Def.Audio card.I will add gear later for streaming and storage.This is for casual play back only through my 2 channel rig.
just checked dac, only one rca and one optical port aval.No optical out on pc.Can i just run 3.5 to dual rca straight to preamp as if it were a tuner?
I take it that your sound card has the 3.5mm output. I see no reason a 3.5mm to dual RCA cable would not work for you. 
Thank you,now do i go cheep or will i benifit from a high quality cable?I am curently pondering on an audioquest cable as they are most commenly stocked.How far far up the chain should i go based on my pc limitations?Thaks again as i think I'm on track now.RW
