Duketbrd88,
I use and can highly recommend a couple of Zavfino power cords: Majestic MKII and the Prima MKII, both OCC copper cords.....cryo treated, and broken in to an extent. The Prima MKII is taking longer to break in, the Majestic needed about 100 hours, but the Prima is on 200 hours and still improving....both would be great for an amp.
Also would recommend upgrading your power receptacles if you have not done so already: Furutech GTX-D(G-Gold), Furutech GTX-D(R-Rhodium), or the Oyaide R1.....I prefer the GTX-D(G) and the Oyaide R1.....but several others have disagreed, and strongly support the GTX-D(R)
