Like new Conrad-Johnson MF-2250A MF2250A - Power Amplifier. Signature required. Conrad-Johnson MF-2250AConrad-Johnsons MF2250 is a successful product on many grounds. It closely approaches the classic tonal character of a fine tubed amplifier—a C-J hallmark—and holds on to that quality over a great range of output power and possible speaker loading. Not easy to accomplish. It also avoids the cheap, quick thrill of a bright, fast, forward sound. Instead, it builds on quality and depth of performance to achieve its commendable rating. Its sound is musically entertaining without being hyperactive, while its broad, bighearted approach is easy on the ears. All kinds of music were handled with equanimity. In the lab, the MF2500s high output power and good load tolerance were confirmed. The amplifier could dump up to 900Wpc into 2 ohm loads for short-term peaks, and cruise happily at around 300Wpc driving 8 ohm loads. This matches the attainment of significantly more costly amplifiers. Except for the modest channel separation at high frequencies, no test result gave rise to concern. Well-built and well-finished, with effective if old-fashioned circuit protection, the MF2500 idled at quite low power and could be safely left on for extended listening periods. This musically well-balanced powerhouse represents fine dollar value, and wins a warm recommendation.Power Output:MF2250 - 120 watts per channel; All deliver their power from 20Hz to 20KHz at no more than 1% THD and IM, both channels driven into 8 ohms.Distortion:less than .1% THD or IMDResponse:bandpass 20Hz to more than 20kHz , +0, -.5dBHum & Noise:100 dB relative to max outputMechanical:MF2250 - 19 X 4 ¼ X 16
