About the MF2550 SS
The Conrad-Johnson MF-2550 SS amplifier is a solid-state stereo amplifier known for its robust performance and detailed sound quality. It delivers 250 watts per channel from 20 Hz to 20 kHz with a total harmonic distortion (THD) or intermodulation distortion (IMD) of no more than 1.0% when both channels are driven into 8 ohms. The amplifier features a MOSFET gain stage at the input, followed by a buffer stage, and uses bipolar devices in the output stage, similar to those in the Premier 350. It is praised for its ability to handle complex speaker loads with ease, providing a soundstage that is both detailed and expansive. The MF-2550 SE version is noted for its improved performance after a break-in period, offering a fast, detailed, and transparent sound.
