PS Audio Stellar Gain Cell DAC Review 2025 Overview
The PS Audio Stellar Gain Cell DAC is an integrated digital preamplifier and DAC. Its main purpose is to serve as the heart of a high-quality audio system, taking digital signals from various sources—like a computer, CD transport, or TV—and converting them to analog while also providing source selection and volume control. This all-in-one approach is designed to reduce the number of components and cables in your signal path, which theoretically preserves more of the original audio information. In practice, I found this to be true, with a noticeable lack of the haze or noise that can be introduced by lesser preamp stages.
This product is designed for the discerning music listener who is building a two-channel stereo system. It’s perfect for someone who owns a power amplifier or active speakers and wants a single, high-performance control unit. Key specifications include support for PCM data up to 32-bit/384kHz and DSD64/128, ensuring compatibility with high-resolution audio files. It features a variety of digital inputs: USB, Coaxial, Optical, and AES/EBU. The standout detail is the absence of a traditional analog preamp circuit; instead, it uses a proprietary Gain Cell for volume attenuation, which is a significant part of its sonic success.

Key Features & Performance
During my evaluation, several key features of the Stellar Gain Cell DAC directly contributed to its impressive performance. The synergy between its components is what sets it apart from simply stacking a separate DAC and preamp.
The Gain Cell Volume Control
This is the cornerstone of the entire product. Unlike standard preamplifiers that use resistor-based potentiometers or stepped attenuators, the Gain Cell is an active, fully discrete, class-A circuit that controls volume by varying gain. The benefit is a complete absence of the channel imbalance and high-frequency loss that can occur at low volume settings with traditional pots. In my experience, the sound remained stable and focused at any volume level, with a black background that made quiet passages incredibly revealing.
High-Resolution DAC Section
The digital-to-analog conversion is handled by a robust section built around a high-performance chipset. It handled everything from standard Redbook CD quality to my library of 24-bit/192kHz files with ease. The sound was never harsh or overly analytical; instead, it presented music with a natural tonality and excellent transient speed. When comparing it to other DACs in its class, I noticed a greater sense of ease and flow to the music, with cymbal crashes and acoustic guitar plucks having a lifelike texture and decay.
Build Quality and Design
The unit feels substantial and well-made. The chassis is rigid, damping internal vibrations, and the connectors on the back panel are high-quality and securely mounted. The front panel is minimalist, with a central display and a single knob for input selection and volume. While some might prefer more buttons or a remote with direct input selection, the simplicity grew on me. It reinforces the product’s philosophy: focus on the audio signal above all else. The unit ran cool and silent throughout my testing period.
System Integration and Usability
Integrating the Stellar Gain Cell DAC into my system was straightforward. I connected it directly to a power amplifier and used the USB input from my computer and an optical input from my TV. The remote control is simple and functional, allowing for volume adjustment and input cycling from across the room. The lack of a built-in streamer or advanced digital features like MQA might be a consideration for some, but for a pure, source-agnostic system, its performance is exceptional.

Final Verdict
After thoroughly testing the PS Audio Stellar Gain Cell DAC, I can confidently recommend it as a top-tier solution for audiophiles seeking a streamlined, high-performance system. Its integrated design and innovative technology deliver a sonic purity that is difficult to match with separate components at a similar level.
Pros
- The Gain Cell volume control provides flawless channel balance and a noise-free background at any listening level.
- Sound quality is exceptionally clean, dynamic, and musically engaging.
- Superb build quality ensures long-term reliability.
- Simplifies system setup by combining a top-notch DAC and preamp in one box.
Cons
- No built-in streaming or wireless connectivity, which may require additional components for some users.
- The minimalist interface lacks some user-friendly features like input naming or a more informative display.
I would strongly recommend this product to anyone using a power amplifier or active speakers who wants a no-compromise control center. It’s perfect for the listener who values sonic integrity above extra features. However, if your primary need is a all-in-one streamer-DAC-preamp, you may need to look at other options that include those network capabilities. For pure sound quality and system simplification, the Stellar Gain Cell DAC is a resounding success.
