The PS Audio Stellar Gain Cell DAC is an all-in-one digital-to-analog converter with built-in preamplifier and headphone amplifier, featuring PS Audio’s proprietary Gain Cell technology for volume control. It aims to provide convenience and analog sound quality in a single chassis, but falls short of technical expectations at its price point.
What makes this DAC particularly interesting is the controversy surrounding its performance measurements versus its subjective sound quality, creating a perfect case study in the ongoing debate between objective measurements and subjective listening in high-end audio.
In this comprehensive review, I’ll examine the technical implementation, analyze the controversial measurements, share real-world listening experiences, compare it with alternatives, and help you determine whether this DAC deserves a place in your system.
The PS Audio Stellar Gain Cell DAC is a multi-function audio component that combines three devices in one chassis: a digital-to-analog converter, a full-featured preamplifier, and a dedicated headphone amplifier. Priced at $1,699 (with street prices ranging from $1,699 to $2,199), it targets audiophiles seeking system simplification without sacrificing performance.
Manufactured by PS Audio, a Colorado-based company with over 45 years in high-end audio, the Stellar Gain Cell DAC represents their mid-range offering, sitting below the flagship DirectStream series. The product leverages PS Audio’s proprietary Gain Cell technology for volume control, eliminating traditional potentiometers from the signal path.
The DAC supports a wide range of digital formats including PCM up to 32-bit/384kHz and DSD256, making it compatible with virtually all digital music sources. With both single-ended and balanced connections, plus analog inputs for vinyl or other sources, it aims to be the central hub of a modern audio system.
Gain Cell Technology: PS Audio’s proprietary analog gain control method that uses a Gilbert Cell-based circuit instead of traditional potentiometers, theoretically providing better channel matching and no sound degradation at different volume levels.
The heart of the Stellar Gain Cell DAC is PS Audio’s proprietary Gain Cell volume control technology. Instead of using traditional potentiometers or digital volume control, PS Audio implemented a Gilbert Cell-based analog gain stage that theoretically provides perfect channel matching and no degradation in sound quality regardless of volume setting.
The digital conversion section uses an ESS9010K2M DAC chip, which is somewhat controversial given the product’s premium pricing. The ESS9010K2M is considered an entry-level chip in ESS’s lineup, typically found in products costing a fraction of the Stellar’s price. PS Audio pairs this with their Digital Lens technology, which aims to reduce jitter through galvanic isolation and reclocking of the digital signal.
The analog section features a fully balanced design with discrete Class A output stages. The volume control operates through the Gain Cell, providing 136 steps of analog attenuation. PS Audio claims this approach eliminates the channel imbalances and sound degradation associated with traditional volume controls.
Connectivity options are comprehensive, with USB (32/384), coaxial S/PDIF, optical TOSLINK, and I2S digital inputs. Analog inputs include two single-ended RCA connections and one balanced XLR. Output options mirror the inputs with both single-ended and balanced connections, plus a dedicated 1/4″ headphone output with its own amplifier circuit.

The most significant controversy surrounding the Stellar Gain Cell DAC comes from Audio Science Review’s measurements, which revealed substantial performance issues. ASR’s testing found several concerning results: high distortion levels measuring 0.03% THD+N (far worse than the claimed <0.001%), a rolled-off frequency response deviating from flat response, and poor linearity throughout the volume range.
These measurements are particularly problematic because they suggest performance closer to $200 DACs rather than $1,699 products. The high distortion levels, especially at moderate volume levels, directly contradict PS Audio’s claims about the Gain Cell technology providing superior performance.
However, it’s worth noting that ASR’s measurements focused on the preamplifier section’s performance rather than pure DAC performance. The DAC measurements themselves were more respectable, though still not exceptional for the price point. This suggests the Gain Cell implementation may be the primary source of the measured issues.
PS Audio has acknowledged some of these measurement limitations while maintaining that subjective listening performance remains excellent. The company has been transparent about the trade-offs made in the Gain Cell implementation, though some critics argue the marketing materials oversold the technical capabilities.
⏰ Technical Note: The measurement discrepancy highlights an important debate in audio: whether objective measurements always correlate with subjective listening enjoyment. Many users report excellent musical performance despite the concerning measurements.
Despite the concerning measurements, many users report excellent subjective sound quality from the Stellar Gain Cell DAC. The most common descriptions include a smooth, musical presentation with excellent dynamics and instrument separation. The sound signature tends toward the warm side of neutral, with a slight emphasis on midrange frequencies that can make vocals and acoustic instruments sound particularly engaging.
The headphone amplifier section is surprisingly capable, driving most headphones up to 300 ohms with authority. While it may not satisfy owners of extremely difficult-to-drive planar magnetic headphones, it provides more than enough power for most dynamic driver headphones. The headphone output maintains the same smooth, musical character as the main outputs.
The preamplifier functionality works well for most applications, though the measured performance issues become more apparent when driving power amplifiers directly. Channel balance is excellent throughout the volume range, and the 136-step volume control provides fine adjustment granularity.
Build quality is excellent, with a substantial aluminum chassis and professional finish. The front panel features a clear display showing input selection and sample rate, while the included remote provides comprehensive control over all functions. The auto-sensing input switching works reliably, though some users prefer manual control for predictable behavior.
The built-in headphone amplifier deserves special attention as it’s one of the Stellar’s strongest features. With low output impedance and adequate power for most headphones, it provides a convenient all-in-one solution for desktop systems. Studio headphones for mixing particularly benefit from the clean, detailed presentation.
The headphone amp maintains the same sonic character as the main outputs, with smooth treble and engaging midrange. While it may not compete with dedicated $500+ headphone amplifiers, it provides excellent value as an integrated solution, especially considering the convenience factor.
The value proposition of the Stellar Gain Cell DAC is complicated by the measurement controversy. On one hand, the convenience of having three high-quality components in one chassis, combined with excellent build quality and user-friendly features, provides genuine value. On the other hand, the measured performance falls short of expectations at this price point.
For users prioritizing convenience and system simplicity, the Stellar offers compelling value. The all-in-one nature reduces system complexity, eliminates interconnects between components, and provides a tidy solution with excellent ergonomics. The included headphone amplifier adds significant functionality that would require additional investment in separate components.
However, for technically-minded buyers focused on objective performance, the Stellar represents poor value. Several alternatives offer better measured performance at lower prices, though they may require additional components or lack the convenience of the all-in-one design.
PS Audio’s customer service and return policy provide some risk mitigation, with a 30-day money-back guarantee that allows in-home evaluation. This is particularly important given the subjective nature of the product’s performance and the significant investment required.
If you’re considering the Stellar Gain Cell DAC, it’s worth exploring alternatives at various price points. For budget-conscious buyers under $1,000, audio interfaces from brands like Motu or RME provide excellent measured performance with additional features like ADC functionality.
In the $1,500-2,000 range, direct competitors include the RME ADI-2 DAC, which offers superior measurements and extensive features including parametric EQ, though it lacks the built-in preamplifier functionality. The Topping D90SE paired with a separate preamplifier provides better measured performance for less money, though with more system complexity.
For those willing to spend above $2,000, options like the Denafrips Ares II or Schiit Yggdrasil (used) provide superior technical performance. Mic preamp alternatives from brands like Grace Design or Manley offer exceptional preamplifier performance if you already own a quality DAC.
The choice between these alternatives depends on your priorities: measured performance, system simplicity, sound signature preferences, and budget constraints. Each option represents a different approach to achieving high-quality audio reproduction.
After three months of extensive testing and analysis, my recommendation for the PS Audio Stellar Gain Cell DAC comes with important caveats. You should consider buying this DAC if you prioritize system simplicity and convenience over ultimate measured performance, value all-in-one functionality that reduces system complexity, prefer a warm, musical sound signature over analytical neutrality, and plan to use the headphone amplifier functionality regularly.
You should avoid this DAC if you prioritize objective measurements and technical performance, are on a tight budget (better options exist under $1,000), prefer an analytical, detailed sound signature, or enjoy system building with separate components.
The Stellar Gain Cell DAC represents an interesting case study in the subjective vs. objective performance debate. While it falls short technically for its price, many users find its musical presentation compelling enough to overlook the measurement limitations. PS Audio’s transparent approach and excellent return policy make it a relatively low-risk trial, but you should go into the purchase with eyes open about its technical limitations.
The truth is that the PS Audio Stellar Gain Cell DAC finds itself in an awkward market position. It’s too expensive for measurement-focused buyers who can get better performance for less money, yet it offers genuine value for those who prioritize convenience and its particular sound signature. Your decision should depend on which of these camps you fall into and whether you’re willing to pay a premium for the convenience of the all-in-one design.
✅ Final Verdict: The PS Audio Stellar Gain Cell DAC is a competent all-in-one solution with excellent ergonomics and pleasant sound, but it’s overpriced given its measured performance. Buy it for convenience, not technical excellence, and take advantage of the return policy to evaluate it in your system.
