The trusty MC33178 (and its quad version MC33179) is a reasonably powerful part (up to 80 mA source, 100 mA sink) with usable GBW and slew rate specs (5 MHz, 2 V/µs) that runs at a puny 420 µA per amplifier. It is particularly recommended for telephony applications, and indeed, a unity-gain follower driving 20 kHz at 2 Vpp into 600 ohms at 0.024% THD sounds hardly awe-inspiring. The npn-only AB output stage isn't too bad, but its symmetry is inherently limited, and it would have to be running at very small quiescent current. Performance should much improve with a few mA worth of Class A bias. The emitter follower on the sourcing side seems more trustworthy than the common emitter circuit on the sinking side, as it would always keep compensation capacitance well away from the outside world and seems to have slightly lower output impedance as well.

Astatic Corp was based on Conneaut Ohio for many years. Although they primarily produced microphones for voice-frequency communications work, they also made higher-fidelity models which are much less common. The company reorganized as Omnitronics LLC in 2000, and later combined CAD, Astatic and Omnitronics under the CAD Audio brand.
Model PM-9000 power module houses microphone electronics and features a superior low noise transformerless design for optimum frequency response. The PM-9000 power module also includes a switchable 12dB per octave high pass filter. The PM-9000 can be mounted either with 4 mounting screws or double-sided foam tape.
