Westlake Audio’s Cable Muffs
“We have a rule in the company to keep cables between 2” and 4” apart,” he said. “Putting left and right channels too close together can increase crosstalk, while positioning them too far apart may lead them to generate and pick up interference.” I hope I got that right.
Westlake Audio manufactures cable muffs with a number of different size holes and slots to accommodate a wide assortment of cables other than the extremely thick variety. Prices range between $59.50 and $88/set.
