Technical Info:
* Zero Crosstalk Sound Image Localization is more accurate the sound is purer.
* Purifi’s “1ET400A” module (and similar) is a very highly regarded Class-D amplifier module, with extremely low distortion (THD+N < 0.00017 % at ~100 W, 4 Ω) and extremely high signal-to-noise ratios (≈131 dB) in lab conditions.
* It uses switching power supply + efficient Class-D architecture — so you can expect good efficiency, less heat compared with big Class A/AB amps. For example the spec sheet: “Efficiency >94%” for Purifi 1ET400A.
