H类放大器
H类放大器调制其电源电压，最大程度减小输出级的压降。实现方法包括从使用多个分立式电压到无限可调电源等。尽管与G类放大器降低输出器件功耗的技术相类似，但H类放大器结构不要求多个电源。

H类放大器一般比其它音频放大器设计更复杂。这些放大器要求精确的控制电路，以预测和控制电源电压。音频编解码IC，例如MAX98090和MAX98091，集成了AB类耳机放大器和H类电源结构，实现了极低功耗、提供了完备的音频方案。

H类音频放大器降低了输出器件的功耗，放大器的工作效率与优化的AB类放大器相当，而与输出功率无关。

There are a number of questions that you need to ask yourself before buying an amp or AVR.

Here are some questions which might help you:

What is my budget?
Am I looking amp for movies or music only?
Do I need 5.1 or 5.1.2(atmos) or even bigger system?
Space constraints (bookself speakers or floorstanders)
Do I prefer sound over features (Bluetooth wifi heos etc)
One more important thing is the sound you like, most of the AVRs in market around 50k will produce decent sound and you need to go and audition them before you buy.

I hope this helps
