Your Favorite High Quality Audio Bulk Cable Manufacturer?

Duelund stranded copper wire in cotton. Just real  sounding and so natural in tone. A killer value. 

I absolutely second grannyring's recommendation with the Dueland cable.  Pick your terminations.   Fabulous wire for both IC's and for speaker cables.  The sound of the wire is so clean, clear, and extended that it surprises me that more folks like aren't devotees of it.  It sounds rather like "no wire at all."  Similar bulk wire is made by Supra and I can say that their Ply 3.4  is excellent and very affordable wire -- as well tin-clad copper wire in a PFTE jacket.   The Dueland cloth-coated wire is more revealing for reasons I don't understand, but readily accept.  16ga Dueland wiring for speakers is just fine.  

Hey thanks for the comments.

Who actually manufactures the Dueland cable? Also, Supra...

Any idea who actually is the manufacturer of the cable product for those brands?

How do the cables hold up to bending and movement? 

1X,
Dueland wire is made by Dueland, who also makes the finest capacitors on earth.  It is sold in North America through Parts Connexion.  Supra wire, also very good wire, is sold through Madisound.  Both cables small in diameter and very flexible.  You could spend 5-10X the amount of money on other speaker wire and not be better off. Just my two-cents worth.
