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

Somehow I seem to have let myself get confused. After rereading this thread I am now aware that you have a soundcard with coax output and a DAC with coax input. I would use a 1.5M coax between soundcard and DAC. Use a Pair of RCA interconnects of the desired distance between DAC and preamp input. 
I only have a single rca input on dac. see 8th post.can i use a non digital single cable for now?Just trying to hear music from main syst.I'll ad the good equip. later.
Adapter coming from Amazon.Under 5.00 delivered.Can't go wrong cost wise.Tuner seems useless when i get stations online that don't come in locally.RW
So much for a single adapter as it is only avail. as mono.I won't be going through my dac now.Had to go pc to pre.Basic sound without emotion.It will require a dac to shine.My BAT pre shows just how limited my pc is.I have an all in 1. It does not offer any rca outs for external speakers.It has been interesting trying stuff out though.The sound is ok for chopping veggies as is casual listening.Guess i'll get a dac .Dragonfly red should better the signal.This is only an alternant for a tuner that gets limited stations with dropouts and signals that arrive only at certain times of day.At least I still get music.RW
