SRM-700S is an answer to every Stax Audio fan's dream: a successor to the ever-present SRM-353X, topped with POWER. An all solid-stage design – capitalising on advances that power FETs have made in recent years to drive even the frightening proposition that is a SR-007 MKII – the direct sonic nature of this amplifier is wonderful for breathing life into any Stax.
Transparency is a given but so is engagement. SRM-700S is buzzing with a different level of mid-range and treble enthusiasm to its SRM-700T sibling, helping expose the nuances the oldest electrostatic headphone company can unearth and entertaining all the while.
What Hi-Fi? give this release a full 5 ⭐ for an amplifier that "is so good that it should be your electrostatic headphone drive amplifier of choice". SoundStageAustralia adds a Stax headphone heard through the SRM-700S "challenges even the best of speakers and set-ups with their accuracy and life-like performance".
Also think about building a pseudo-full size earspeaker system with SRM-700S operating as a pure power amplifier. Front your system with Benchmark Media's DAC3 and HPA4 – Head-Fi's most precise pre-amp volume control – for that.
