The Stax SR-X Mk3 Pro is a distinctive pair of electrostatic headphones that combines elements from earlier models with modern appeal. Featuring drivers similar to those found in the Gamma Pro and Alpha Pro models, the SR-X Mk3 Pro uses the housing of the more common SR-X M3, making it a unique offering within the Stax lineup. As a supra-aural design, the headphones boast an aesthetically pleasing industrial look, though user experiences indicate that comfort is compromised due to a less-than-ideal headband design.
In terms of sonic performance, the SR-X Mk3 Pro is characterized by its linear frequency response and powerful deep bass that is complemented by a clean midrange, revealing the nuances of recordings. Although it excels with high-quality sources, its performance can be somewhat dependent on what is played through it. Users report that the sound signature leans towards the monitor-like end of the spectrum, providing clarity and precision without adding coloration to the music.
The clarity extends to vocal reproduction, which is crisp and articulate, while the treble is extended and present without veering into sibilance. However, there may be a noticeable harshness in poorly recorded tracks, particularly in the upper midrange frequencies around 3 kHz. While the SR-X Mk3 Pro can showcase the dynamic elements of recordings, it may not fully engage with genres like classic rock that often rely on warmth and color.
Amplification is an integral aspect of the listening experience with the SR-X Mk3 Pro, with recommendations suggesting compatible models like the SRM-1 Mk2 Pro or SRM-T1S that provide sufficient power and control. Using a less capable amplifier might result in compromised bass control and a loss of detail in the upper frequencies. The choice of source is equally critical; higher quality sources tend to unlock the full potential of the SR-X Mk3 Pro, transforming the listening experience from artificial to lifelike. Many users note a significant enhancement in sound quality when pairing it with improved DACs and amplifiers.
Overall, the Stax SR-X Mk3 Pro acts as a transparent conduit for audio playback, rewarding listeners with an authentic representation of the material when paired with quality source equipment.
