Which is the best Buy: Shielded and Unshielded Ethernet Cables?

Digital Signal Processing is the process of transmission and production of data that takes place without any interference. This process asks for an Ethernet Cable. Most of the wired networks of today including routers, PCs and switches use Ethernet cables for the smooth transmission of data. These Ethernet Cables are of two types – Shielded and Unshielded. They are also known as STP (Shielded Twisted Pair) and UTP (Unshielded Twisted Pair). The question that arises next is - which one out of the two you should buy? To find this out, make sure you know about the environment you need Ethernet cables for.

I agree with what  @sfcable states - only you know your environment.

Are you in a particularity noisy environment like an office - or a quieter space like an apartment or house?

Screened Ethernet cables are really designed to maximize transmission rates in an office or industrial space where there are hundreds of feet of cable lying side by side.

Home environments tend to be very quiet by comparison.

My house is wired with un-screened CAT6 and I have not experienced any problems with my content streaming of music or video.

Save your cash  and spend that money on more hi-fi stuff :-)

Unless you have a really noisy and crazy environment you are running the cable through UTP should be just fine. I have UTP cat5e I ran years and years ago, every once in a while I put a managed switch on the network and never found any dropped packets.
