2023 Winter Issue HiFi Bible – Charlie Ma’s Notes Testing Notes: Audio Note AN-S1 H (L) Pure Copper Moving Coil Head Amplifier
“This fixed impedance version of AN-S1 H has the characteristics of a pure copper amplifier; the undertone is pure and rich, especially when replaying singing vocals. Even pure silver MCs cannot compete with the AN-S1 H’s sense of solid composure and high density⋯ Compared to the old model, it adds a sense of stability especially when playing large-scale classical movements. The sound stage and shape present listeners with a more accurate vision. As the music climaxes and subsides, it makes people listen with more comfort.”
