剛剛看了一下AMB網站上的介紹
β22 ("beta 22") is a high-end, reference-quality DIY stereo amplifier for dynamic headphones
The all-discrete (no integrated circuits), fully complementary and cascoded topology, high-current MOSFET output stage, full class A operation and carefully tuned operating points provide vanishingly low distortion, high speed, wide bandwidth, low output impedance, and high output power. All elements of the design were critically examined to create an amplifier that performs as well on the test bench as it does with music
MOSFET純A類3ch設計
看的我心好癢
啊
It could also be built as a power amplifier for speakers (18Wrms into 8Ω unbalanced, or 50Wrms into 8Ω fully-balanced), or as a preamplifier.
真是驚人XD
好像很值得一玩
