Ethernet

I hope you mean "Ethernet switch" instead of "splitter."

Keep in mind that Cat 5 cable has about 100x more bandwidth than audio or even video requires.  Going to a higher cat than your source and switch supports doesn't help anything.  Using shielded however may help.

Also, with long runs you run the risk of picking up an induced surge from a local lightning strike.  I encourage you to use a certified isolator (UL60601 or ISA60601) on the side closest to your more expensive gear, or one on each end.  More about that here.

Erik - Yes, sorry. 

Thank you...  A "non audiophile" buddy said the same thing about moving up from Cat 5...  He couldn't see the reason.  I'll look into the isolator.

@erik_squires I am not an IT professional. I believe you are though.

Going to a higher cat than your source and switch supports doesn’t help anything.

The OP didn’t say what type of internet/speed he has coming into his house. I think that would be a good thing to know, therein a starting point as you said in the above quote, source. Good chance he may be stuck with what he has. It may only justify Cat 5e cable as you said.

His switch may only support the use of a Cat 5e cable.

Just curious if his incoming internet will support Cat 6a would he gain anything by buying a switch that would support Cat 6 or Cat 6a cable?

From the specs, RS130 Network Transport

Network:

SFP Ethernet 10/100/1000 BASE-T(SFP COPPER Type)

 

Justify Cat 6 or Cat 6a  cable?

.

Internet speed is a blistering 23.09 mbps upload and 825 mbps download, great question.  Just ordered a Cat6a SHIELDED set up.  Thank you all.

For 1 you want a 4+amp Linear Power Supply  to the router  which btw digital is not grounded, for a solid Best Buy and quality ,LHY - SW-6 Ethernet hub for $600

nothing close with a LPS, , low noise regulators, and a temp control clock ,
