[Big Red Machine]

About a meter long.
I bought these to try them and loved them, so I bought a second set in XLR as I prefer the higher gain playback in my system.
Check out their website if you want to know more about what cables do and not do. Stop buying the same old copper wire everyone else sells.
These are terrific at subtly laying out the details in the music without being aggressive or hyped up.
