JBL SA550 Classic

A modern integrated amplifier with Bluetooth, styled in retro form and inspired by JBL's classic 1960s designs

Overview

The JBL SA550 Classic is a contemporary integrated amplifier that pays homage to JBL's heritage, drawing direct inspiration from the 1960s JBL SA600. While not a vintage model itself, it captures the aesthetic and spirit of JBL's golden era of audio design with its retro styling and walnut veneer side panels. It combines this nostalgic look with modern features including Bluetooth connectivity and a high-resolution DAC for digital audio playback.

Delivering 90 watts per channel into 8 ohms (and 150 watts into 4 ohms), the SA550 Classic uses Class G amplifier technology to achieve high power output with improved efficiency and low noise performance. Its phono input supports the RIAA curve with a frequency response of 20Hz to 20kHz ±1dB, making it suitable for turntable use.
