Speaker wire... Diy?


I am new to this, so please bare with me. I always thought 12 gauge speaker wire, bare on each end, was best. But there is Kimber, Nord, etc, that seem to be incrementally better! Can I buy the components and put together my own $17000 speaker wires? If so, where can they be purchased, and which are good enough to be used? Which terminations are best for sound? Which wire? Length? Guage?

Cables interact with the system. There is no guaranteed better. All the various geometries are tone controls. They may sound well in one system/room, no different in another and terrible in a third.

A large reason for the lunacy of the audiophile world is ill educated consumers taking recommendations from ill educated sales persons. Many people have no idea how to assemble a system. That includes most dealers.

NEVER take any recommendation from anyone, anywhere that does not have an identical system, room and TASTE to yours. Only make cable purchases that have OHPNQAMBG - One Hundred Percent No Questions Asked Money Back Guarantee.

For examples of how the same cable reacts with different loads and how different cable reacts with the same load see http://ielogical.com/Audio/CableSnakeOil.php. Be sure to read Garen Galeis papers.

Just get some Duelund 12ga wire in the length you need.  Try it bare or for ease of use install some spades or banana connectors.  I use the KLEI banana connectors with excellent results.  Several at our audio club use it and have no desire to spend big bucks on speaker cable. 

Just get some Duelund 12ga
Talk about overpriced low tech. Little different than THHN 12ga @ 50¢/m.
It may sound a little different, but unlikely better.
