Features: a) Adopts amplifier of dynamic feedback which has both current feedback and voltage feedback.When the Zo (speaker load) becomes small,it uses voltage feedback.And when the Zo is changed continuously, using both current feedback and voltage feedback simultaneously. b) It has a high SNR and you can hear no noise.Tone quality is warm with jumping ability.The intermediate and high frequency are clear and transparent,while the low frequency feels bursting with strong.The performance of...

Features: 1. The former part of the use of non-negative feedback of low distortion of the tube + FET to do pre-amplification. 2. Using 6N1 (6DJ8, ECC88) tube input to do a common cathode voltage amplification. 3. Hitachi 2SK216 field effect transistor for the former class current output. 4. Before the input signal line using the US monster signal line. 5. Amplifier Each channel uses two US low-distortion BTL LM3886T balanced output form of push-pull output. 6. Power supply part of the Panasonic...

G&W TW-A1.3SE single-ended Class A hi-fi preamplifier Gawain circuit pre-amp new Feature: The G&W TW-A1.3SE is a pure single-ended Class A preamplifier with 4 RCA signal inputs and 1 set of outputs This is a single-ended Class A pre-amplifier, it has a good linearity, each output transistor is amplified signal full wave, there is no cross-distortion. Performance in the sound will make people feel clear and transparent, prominent texture, sound superior and so on. TW-A1.3SE or classic dual...
