I've experimented rather extensively with DIY power cords and have found, with my equipment, that the Cryo-Parts is quite superior to DIY Crump, DIY Flavor 4 with Belden 83802, Volex, & DH Labs. All of the others were only marginal improvements over a stock cord. If I'd stopped experimenting before trying the Cryo-Parts, I'd have validated my skeptical outlook on aftermarket power cords. Pretty much instantly after installing the Cryo-Parts on my amp, I knew that this was a real, audible, and substantive upgrade.
