Brand: Sansui

The Sansui SP-5500X is a high-end stereo integrated amplifier that was manufactured by the Japanese audio equipment company Sansui in the late 1980s. It features a power output of 85 watts per channel into 8 ohms and a frequency response of 20Hz to 50kHz. The amplifier also has a number of advanced features, including a multistage input circuit, a microprocessor-controlled volume control, and a linear power supply. The SP-5500X is known for its exceptional sound quality, particularly in terms of transparency, detail, and dynamics.Here's a breakdown of some of its technical specifications:Input section:- Total: 7 line-level inputs (4 RCA, 2 DB-25, 1 XLR)- Impedance: 25k ohms (RCA) / 100k ohms (DB-25) / 100k ohms (XLR)- Input level: RCA: 2.2V RMS / DB-25: 2V RMS / XLR: 4V RMSOutput section:- Output power (8 ohms): 85 watts per channel- Output power (4 ohms): 170 watts per channel- Output impedance: 220 ohmsTone control:- Bass: +/- 10dB @ 50Hz- Treble: +/- 10dB @ 30kHzRemote control:- IR input and outputDimensions:- Width: 435 mm (17.1 inches)- Height: 140 mm (5.5 inches)- Depth: 385 mm (15.2 inches)While the Sansui SP-5500X is a very capable amplifier, it's important to note that audio equipment can depreciate over time, and prices may vary depending on the condition and availability of the unit. However, as of my research in 2021, a well-maintained, fully-functional unit can sell for several thousand dollars on the secondary market. As with any vintage equipment, it's also important to ensure that the amplifier has been properly serviced and maintained by a reputable technician. Some common issues that may arise with vintage amplifiers include electrolytic capacitor failure, power supply regulation problems, and faulty input or volume control circuits. With proper care and maintenance, however, the Sansui SP-5500X can continue to deliver exceptional sound quality for many years to come.
