Aug 9, 2015 · The Stax SRM-727II is Stax’ top transistor amplifier, based on FET-transistors. It is rated with a maximum output voltage 450 Vrms, which is a bit higher than the 340 Vrms of the 007tII. However, continuous output power ability tells you …

The new SRM-727II employs semiconductor output drive stage and non-feedback (NON-NFB) output stage for the first time ever in a STAX driver unit. A pure balance DC amplifier configuration is used for the large current emitter follower Class A output stage.

Aug 15, 2011 · According to couple reviews posted here including from spritzer (who is extremely knowledgable and owns/has built many different electrostatic amps, BH, KGSS, T2) the Stax Srm-323s is superior to the stock SRM-727a, is very close to the KGSS and will drive both the Sr-009 or the Sr-007 very well.

The SRM-727II features non-feedback (NON-NFB) output stage for the first time ever in STAX drivers. Large current emitter follower Class A amplification circuit. This makes it possible to achieve a much more vivid and dynamic sound quality with frequency response raised to 115kHz.

The STAX SRM-727II is an electrostatic amplifier that employs semiconductor output drive stage and non-feedback (NON-NFB) output stage for the first time ever in a STAX driver unit.

SRM-727MK2 by STAX Audio is a powerful solid-state Class A headphone amplifier for use with their range of electrostatic earspeakers. For the first time ever in a STAX driver unit, the SRM-727MK2 uses a semiconductor output drive stage and a non-feedback output stage.

Feb 26, 2012 · The 727 is a local feedback version of the 717. The 727 has a current source, the 717 has a resistor. Otherwise virtually identical. The 727 runs the output stage at higher power. The kgss and the 717 are similar amplifiers. (4 stage amplifiers)

STAX chose the electrostatic technology for its ability to produce transparent sound, and low weight for comfort/ergonomics, both due to the driver design not employing fixed magnets and moving coils, as opposed to other common headphone driver designs.

The SRM-727II features non-feedback (NON-NFB) output stage for the first time ever in STAX drivers. Large current emitter follower Class A amplification circuit. This makes it possible to achieve a much more vivid and dynamic sound quality with frequency response raised to 115kHz.
