Harmon-owned JBL has its 75th anniversary this year, and is celebrating by dipping into its past to build a new retro-cool integrated amplifier that's based on models from the 1960s and 70s.
The JBL SA750 pays tribute to the SA600 and SA660 hi-fi amps of yesteryear and comes with a vintage-looking aluminum face panel that's home to chunky retro switches and dials, as well as a headphone jack and two-line display panel.
The unit is built around a high-output Class G amplification design, which Harman says offers similar sound quality and performance to a Class A amplifier, with a switching power rail setup offering "high-current capability for extreme power demands." All in, the SA750 delivers 120-W output per channel into eight ohms, or 220-W into four ohms.
It includes its own MM/MC phono stage, so listeners won't have to go out and buy a dedicated pre-amp, and bringing the vintage into the modern world, the design features Wi-Fi with UPnP support and sports streaming technology that supports Chromecast and Apple AirPlay 2.
There's a high-resolution DAC (digital-to-analog converter) inside too, a USB port for plugging in thumb drives, support for MQA decoding (which is designed to offer studio-quality audio while keeping streaming bandwidth relatively low), is compatible with the Roon multi-device music platform, and comes with Dirac Live room calibration technology built in.
