Thanks for your contribution to the thread.
I had been using the Shunyata Research Alfa EF on the Supernait 3 but today it has been retired by the Audio Envy Mega. The Mega offers greater velocity of signal transfer, better transient response and speed, without lag. It’s more honest to the source. The Mega projects holographic imaging and a larger soundstage. It lets more information slip through for a more relaxed listening experience. The Alpha EF sounds thick, slow and veiled by comparison.
I recently had a conversation with Alex Svetisky of WyWires and after the call I was convinced that the Platinum Series power cords are the sweet spot in the line. Very favorably reviewed online, and the Platinum Series cables are currently 40% off.
