The STAX SRS-2170 is a complete entry-level electrostatic headphone system that brings high-end audiophile performance to a compact, easy-to-drive setup. The Basic System includes the acclaimed SR-207 headphones paired with the matching SRM-252S amplifier, carefully tuned to work together as an integrated solution. Priced at $790, this system offers exceptional clarity, speed, and detail at a price point that is remarkably accessible for a true electrostatic rig.
In the United States, the STAX SRS-2170 Basic System is typically offered with shipping included, making the overall value even more compelling. In the UK, pricing and availability may vary, but the combination of the SR-207 and SRM-252S remains a sought-after gateway into the world of electrostatic listening.
What You Get with the STAX SRS-2170
SR-207 Electrostatic Headphones
The SR-207 headphones are at the heart of the SRS-2170 system. Designed with STAX’s signature electrostatic technology, they deliver a sound that is fast, transparent, and highly detailed across the frequency spectrum. The diaphragm is incredibly light and responsive, enabling precise reproduction of micro-dynamics and subtle nuances in recordings.
The SR-207 offers an open-back design, which contributes to a wide, spacious soundstage. Listeners can expect a natural sense of air and instrument separation, making these headphones ideal for complex orchestral works, jazz ensembles, acoustic recordings, and any music where space and realism matter.
SRM-252S Electrostatic Amplifier
The SRM-252S amplifier is the ideal partner for the SR-207 headphones. This compact, solid-state energizer is specifically engineered to supply the high voltage and stable drive that electrostatic drivers demand. Despite its small footprint, it delivers clean, controlled power for a highly transparent listening experience.
The SRM-252S typically offers line-level inputs, allowing easy connection to DACs, CD players, streamers, or integrated amplifiers with pre-outs. Its minimalist design focuses on low noise, reliability, and sonic purity, making it a plug-and-play solution for users who want to experience electrostatic performance without complicated setup.
Sound Quality: What to Expect from the STAX SRS-2170
Detail and Clarity
The defining trait of the STAX SRS-2170 system is its extraordinary detail retrieval. The SR-207 and SRM-252S combination reveals textures and low-level information that many dynamic headphone systems in similar price ranges simply gloss over. Vocals gain articulation and presence, while string instruments and percussive transients are rendered with speed and precision.
Soundstage and Imaging
With its open-back design and electrostatic drivers, the SRS-2170 offers a spacious, airy soundstage. Instruments are positioned with accuracy, and the sense of depth can be striking, especially when paired with high-quality recordings. This makes the system particularly engaging for live albums and classical or cinematic music where immersion is key.
Tonal Balance
The tonal character of the SRS-2170 tends toward neutrality with a touch of brightness that accentuates detail. Bass is clean and articulate rather than exaggerated, focusing on speed and definition instead of sheer impact. Midrange performance is clear and present, ideal for vocals, piano, and acoustic instruments. Treble is extended and revealing, offering sparkle without sacrificing refinement when paired with well-mastered sources.
Design, Comfort, and Build
Lightweight and Comfortable Fit
The SR-207 headphones are built with comfort for long listening sessions in mind. Their lightweight construction, combined with soft ear pads and a self-adjusting headband, helps reduce fatigue. The open design also allows for ventilation, which is beneficial during extended use.
Compact, Desk-Friendly Amplifier
The SRM-252S amplifier is designed to fit easily into a desktop or compact audio setup. Its slim chassis can sit next to a computer, DAC, or small stereo stack without demanding excessive space. This makes the SRS-2170 system an attractive solution for listeners who want reference-quality sound in a home office, bedroom system, or minimalist listening corner.
Value and Pricing Considerations
With a price of $790, the STAX SRS-2170 represents a strategically positioned entry into electrostatic sound. Considering that it includes both the SR-207 headphones and the SRM-252S amplifier, the system compares very favorably to buying separate high-end dynamic headphones and an equivalent amplifier. For listeners in the US, the inclusion of shipping in the price adds to the overall value proposition.
In the UK and other regions, pricing may reflect local import duties, taxes, and distribution costs, but the SRS-2170 remains a compelling option for those seeking an integrated system that captures the essence of the STAX experience without the higher prices commanded by flagship models.
Ideal Use Cases for the STAX SRS-2170
Critical Listening at Home
The SRS-2170 is perfect for dedicated listening spaces where sound quality takes priority. Its open design and precise imaging make it ideal for late-night listening sessions, careful album study, or simply sinking into your favorite playlists with minimal distraction.
Desktop and Studio Environments
Thanks to the compact SRM-252S, the system also works well on a studio desk or workstation. Producers, mixers, and content creators who rely on accurate monitoring will appreciate the honest, detailed presentation of the SR-207 headphones, particularly for evaluating subtle mix decisions and mastering changes.
How the STAX SRS-2170 Compares in the Market
Within its price bracket, the SRS-2170 competes against mid- to upper-tier dynamic headphone setups. While some dynamic designs may offer more pronounced bass or closed-back isolation, the SRS-2170 excels in transparency, speed, and overall refinement. Its electrostatic drivers give it a distinct edge in clarity and spatial realism, especially for acoustic and vocal-centric music.
For listeners who are upgrading from mainstream dynamic headphones, the jump to the SRS-2170 can feel transformative. The system provides a taste of what higher-end STAX models deliver, while remaining far more accessible in terms of cost and system complexity.
System Setup and Optimization
Setting up the STAX SRS-2170 is straightforward. Connect your source component—such as a DAC, CD player, or streamer—to the SRM-252S via its line inputs, then plug the SR-207 into the amplifier’s headphone output. For the best results, pair the system with a clean, high-resolution source and quality interconnects to take full advantage of the electrostatic resolution on offer.
Positioning the SRM-252S on a stable surface with adequate ventilation is recommended, though its power consumption and heat output are moderate compared to larger amplifiers. Regular dusting and basic care will help keep the system performing at its best over the long term.
Who the STAX SRS-2170 Is For
The STAX SRS-2170 is tailored for listeners who:
- Want an authentic introduction to electrostatic headphone performance
- Prefer clarity, speed, and soundstage over heavy bass emphasis
- Need a compact, integrated system that is easy to set up and use
- Value long-term listening comfort and low fatigue
- Are ready to step beyond typical consumer headphones into audiophile territory
