Ordinary lamp cord has a capacitance of 10 20 pF per foot, plus a few picofarads of stray capacitance, so a 50 foot run ( 100 total feet of conductor ) will have less than 1 percent capacitive loss in the audible range.

Ordinary lamp cord has an inductance of 0.1 0.2 ?H / foot, likewise for shielded cord, so a run of up to about 5 feet ( 10 total feet of conductor ) will have less than 1 % inductive loss in the audible range.

Initial sales were slow, because at the time electronics retailers provided low-cost lamp cords to consumers for free Monster is credited with creating the market for high-end audio cables in the 1980s through Lee's " marketing prowess . " He did demonstrations comparing the audio of standard cables to Monster cables for retailers and trained their salespeople to do the same for customers.
