Who is a big high end cable manufacturer

I'm guessing, but besides Monster

MIT
Audioquest
XLO
Straightwire
Nordost
Cardas
Kimber

And many of the (high priced by necessity, not greed) smaller companies make better stuff than any of the biggies. Companies like:

Purist
Transparent
Siltech
Silver Cable
Aural Symphonics
Ridge Street
and many many others.

Have to agree with Nsgarch: Maybe you may want to ask the top ten in "VALUE". You'll find most of them are small companies names. Why pay more and get less?

Home Depot

Belden. Heck, they probably make most of it.
