Shielded Speaker Wire 12AWG

I appreciate all the great guidance and the video about center channel speakers. I am leaning towards the  T-14 Speaker Cable - DH Labs Silver Sonic https://share.google/Wo4rwTXnxtRYcwcu0

Hello cgbgregg, You can also consider Iconoclast spkr cables. Due to room layout, I have 25' runs of Iconoclast TPC. Immediately upon listening to them, my boss who is always concerned about my audio expenses, smiled enthusiastically (!). The design inherently rejects noise, but the point is that even w my long run, they sound clear, revealing, enlarged soundstage, no noise. If your length is more reasonable than mine, they will send you a pair with a 30+ day return. Bob Howard at Iconoclast was very knowledgeable and thoughtful (850-860-0940). I did a ton of research before ordering; No way I am returning mine.   

Blue Jeans Cable sells Belden 10AWG stranded cable. That's what I use.

Vh audio has cryoed wire

And analysis plushas very good awg wire 

 Shielded is not as important

I have  a 4 wire setup a common ground 

And a insulated isolated ground on its own buzz bar to the outside 

Everyday is the same No noise no sharing ground with other appliances 

My Audiophile friend electrician taught me this and breakers are silver over copper 

From Germany this ovoids the copper from oxydizing

Hey OP

you wrote you wanted "connect the speakers with shielded 12awg wire, "

I don't suggest you do that. As per the video, shielding affects the dynamics of sound because of the signals going to the speaker are higher voltage/current swings. just use good speaker cable
