In-wall ethernet cable for streamer


I am running Cat5e (non-shielded) cable inside the wall which I installed myself when my home was being built before they drywalled. It was a bulk box of Cat5e that I ran to multiple rooms. I am running this from the router on the first floor to the room in the basement where my system is for my streamer.
I was thinking I could easily pull new cable through with maybe one drywall repair area in a closet.
1) is it worth the hassle to go to something higher and shielded like a Cat 6 or 7?
2) I do not see anyone selling Cat6 or 7 shielded by the foot? I only need 50' and all I see are bulk rolls of 1000'
Thanks!

Properly installed/ terminated Cat5E has more than enough bandwidth capability for streaming music.  Leave it alone and enjoy.
I would recommend a shielded cable- at the very least.
I have seen Supra cat8 well reviewed, but have no first hand information.
You can buy it on Ebay for a 'reasonable' price.

Much depends on how much RF noise there is in your local environment and adjacent power cables. If that’s not too bad, then your 5e will be fine, otherwise I’d recommend any decent shielded copper Cat6/7. The key with STP is getting the termination right to ensure that you have continuity in shielding - but that’s basic network installation rather than hifi OCD.
