MOREaudio CS100 – integrated amplifier with “tricky” feedback
07.01.2025 12:05 | ~1 minute read
Polish company MOREaudio has introduced a new integrated amplifier CS100, which, according to the manufacturer, “features an innovative topology inspired by the legendary Single-Ended designs” - in this case, we are talking about a system where abandoned the global feedback loop in favor of local feedback at each stage.
For optimum loudspeaker control, a combination of positive and negative feedback is also used to provide an efficient amplifier output with negative output impedance (-150 mOhm!).
The MOREaudio CS100 integrated amplifier guarantees 2 x 100 W power rating (8 Ohms loudspeakers, when using speakers with an impedance of 4 Ohms, the power will increase linearly up to 2 x 200 W), volume control is possible in 1 dB steps in the range from 0 dB to -64 dB.
MOREaudio CS100 operates in the frequency range of 5 Hz - 120 kHz (-1 dB) and has an extremely low total harmonic distortion + noise of 0.05%. With an input sensitivity of 600 mV, the amplifier provides comfortable matching in a wide range of components.
