The Stax SRM-1 MK2 Pro is an electrostatic headphone amplifier designed to provide ample power for driving electrostatic headphones, particularly the Lambda series. It features both pro and normal bias sockets, a DC-coupled architecture, and operates in pure class-A mode, ensuring uncolored sound reproduction across the audio spectrum. Users appreciate its clear audio delivery, from deep bass to detailed treble, without roll-offs or bloat. The amplifier is equipped with a voltage switch on some models and includes options for rewiring to balanced inputs. Notably, it is often recommended for use with higher-end models like the Omega series as a more affordable alternative to premium amplifiers. However, it might require maintenance like electrolytic capacitor replacements due to aging components. Users have reported that after refurbishing, the unit can deliver outstanding audio performance, even outperforming other models like the SRM-300 and SRM-252 in terms of power and clarity. The build quality is solid and user serviceable, making it a suitable project for audio enthusiasts who are comfortable with electronics. Overall, the unit is a valued choice for those seeking accurate and detailed sound in their electrostatic listening experience.
