Both Jaguar and Jadem6 are correct. I have a few WHALEs and find that they are a true bargain in hi-end power cables. The mamba and viper, electraglide compare to the Eel cable that BMI manufactures. The Whale competes with the Fatboy, King cobra and NBS statement. I had all 3 cables in the past and sold them once I heard the Whale. The Whale outperforms these very expensive cables for about a quarter of the price and saved a lot of money. Kudos to BMI and the Whale. I've gave a number of feedbacks in forums on this great product. Just check earlier forums in the cables.
