I've got the Belden 10 gauge, 8' runs.
As for a "very well established company", Lincoln Walsh invented the speaker design and patented it in 1969. Ohm Speakers was founded in 1972, and John Strohbeem, the current president, has been in that position since 1978.
In my book, a 50 year old company counts as "very well established." Other than the Walsh driver vs horn issue, which obviously have differing sonic traits, the other big difference between Ohm and Klipsch is that Ohm went the direct sales route and Klipsch went big-time retail with Best Buy, Crutchfield, etc.
The only recommendation I have is to listen and pick the speaker that sounds best to you. Ignore what the rest of us think.
