About the SA550 Classic
The JBL Synthesis SA550 Classic is a two-channel Class G integrated stereo amplifier combining a high-current power amplifier, moving-magnet phono stage, analog line inputs, digital audio conversion, Bluetooth, preamp output, and headphone amplification. It uses JBL’s retro-inspired Classic Series styling with a walnut-wood-veneer finish and front-panel level display. The amplifier is designed to deliver 90 W per channel into 8 ohms and 150 W per channel into 4 ohms, with a minimum recommended loudspeaker impedance of 4 ohms. Digital audio is handled by an ESS Sabre ES9038K2M DAC. Bluetooth supports aptX Adaptive and AAC, but the unit does not provide Wi-Fi, Ethernet, AirPlay, Chromecast, Spotify Connect, Tidal Connect, or Roon Ready streaming. Available technical documentation and retailer listings identify it as an active/current product rather than a discontinued model.
