Outstanding quality and value. New - digital camera cable 24G-8:3 - Solid 24 gauge 8-conductor twisted pair wire, category 3,used for phone jacks, door phones, and extra pir control (cheap way ofwiretypecost/ft. Soundtrack says that monsteraudio cable can run up to 10 feet parallel to ac (1 foot from the coax), coaxcan run 25 feet (or much more for monster coax), and other low voltage wirecan run about 2 feet without much chance of problems. Is that what you havein mind?Some folks put individual small amplifiers on each speaker and feed themfrom a switching matrix which allows each amplifier to listen to one ofseveral programs at will. We offer usb camera cable, industry leading digital camera cable solutions, monster cable s video information, and digital camera cable tips. See composite video cable. Therefore, our node 0 is located in the basement, butwe have a central "node 1" for audio distribution, and a third smaller "node2" for security. Wall switchesare sometimes wired with neutral-&-hot coming to the box andneutral-&-switched-hot heading off from the box to the thing controlled; thisvariant will be usable. Actually, a 16-gauge 2-conductor wire was recommended for this,but i had the 22-8 and can always double up the conductors. | 
In our case, things were a little safer since we used tji ("silent floor")joists. Asfor the quality control aspect you mention, billions of feet of copper cladsteel are manufactured each year under very exacting quality standards. Electricians know how to do this, but theindependent telephone jocks really know how to pull a wire throughanything without disturbing the plaster, paneling, etc. This actually provided a benefit beyond what i had planned,since it allowed doubling up the wires for the main speakers; i will just usetwo conductors for each speaker pole connection instead of one, making theeffective gauge of the wire considerably more than even a single 12-gaugewire! Considering the cost of 12-gauge wire, this provided a super mainspeaker wire relatively inexpensively.
