I did a personal "shootout" of about ten power cords of the significant brands from the cable company and four other dealers plus those I own. The AQ Hurricane was the best on my power amp in particular. The Tornado at half the price was so good I probably couldn't tell the difference. Some swear by the entry level Thunder. I now own AQ power cords, my only AQ cables. I would call The Cable Company, ask for Ethan and get his recommendations. You can borrow their cables for shipping cost and 5% of retail. They do most major brands except Nordost. The 5% can be used toward any purchase from them now or in the future.
