那个400到800的真空管的不比这个差

Accurate Digital Technology: JENO Engine (Jitter Elimination and Noise-shaping Optimization), GaN-FET Driver , LAPC (Load Adaptive Phase Calibration),?

真空管是高压线性放大，电流低，原理上没有上面的问题。真空管放大器需要很大很重的变压器。

• Class A design is the least efficient but has the highest sound fidelity.
• Class B design is a little more efficient, but has a lot of distortion.
• Class AB design packs a punch with power efficiency and superb sound.
• Class D design offers the highest efficiency but isn't quite as high-fidelity.?
