Ribbon Cables vs. Standard

As far as I am aware, Nordost, Harmonic Tech, and Neotech are the principal manufacturers of "flat" cables with multiple wires.

Harmonic Tech already posted above.

Silversmith and Goertz make the true ribbon cable.

There are probably others.

Then there are still others that are half way there, like Audio Envy SP-12.

I bought Nordost Blue Heaven under the simplistic assumption that there would be less intertwining of cables and therefore less possibility of ground loops or other unwanted phenomenon that I seemed to be getting with other designs.  I think it worked because I haven't really thought about such phenomena in the years since I purchased them, but there may be some other explanation.  They sound fine to me and I am  not one that stresses much over cables.  I was able to pick up some used Valhalla cables at an estate sale and I don't really notice any difference

Bigtwin, sometimes cables do sound more alike than different. Other times they sound very different. 

Depends on your system the construction and sound.

If you like that airy, detailed sound, that brings you closer to the stage...these Sternklang ribbon cables below for sure will do that. Price is very affordable IMO. Gestalt Audio in Tenn sells them.
