The analog preamplifier is the heart and soul of any high-performance audio system. It’s the point in a system where music’s magic can be won or lost. For more than 45 years, PS Audio has been building preamplifiers that honor the music and preserve the magic. The Stellar Gain Cell DAC is no exception. It features fully balanced class A analog circuitry from input to output, along with a state of the art DAC that ensures perfect symmetry between analog and digital. Rediscover the wealth of music in your library, with Stellar. Rich, sweet, and always a musical treat, Stellar GainCell DAC is our best value in bringing life to music.

Design

The idea of building a no-loss analog preamplifier with its own built-in cutting edge DAC was the basis of the Stellar GainCell design imperative. At this instrument's heart is the analog GainCell. Rather than using additional sonically-degrading elements inserted in the signal path to control volume, the GainCell eliminates this problem without additional circuitry in the signal path by varying its gain in response to front panel controls. Based on industry leading Sabre32 bit Hyperstream architecture, Stellar DAC features a fully balanced Class A analog output stage with multiple power supplies, independent jitter-reduced inputs, DSD, I2S, and asynchronous USB.

Application

The Stellar GainCell DAC is a full function analog preamplifier featuring a state of the art built in Digital to Analog Converter inside. It is all you need as the basis of a reference quality music system. Add a power amplifier and a pair of loudspeakers and you'll be reveling in sonic bliss within moments. Connect a computer, CD player, or digital source to any of Stellar's multiple digital inputs, or a Stellar Phono Preamplifier to its analog ins, and you've just built one of the highest value music systems in the world.

Technology

Overview

Think of the Stellar GainCell DAC as a complete analog control center with an exceptional performing DAC at its heart. All the features and functions you’d ever want in an analog preamplifier and modern DAC are right here in Stellar. A zero-loss, fully balanced, pure, analog signal path combined with DAC features rarely found at any price level: pure DSD, asynchronous USB, Digital Lens technology, I²S to connect to our best transport, balanced throughout. Replace your preamplifier, your DAC—or both—and be stunned at the level of improvement when the full and rich tapestry of music surprises and delights your senses. Together, or separately, they create an extraordinarily rich, full-bodied musical experience few standalone products can match. The Stellar Gain Cell is the perfect foundation for those unwilling to compromise sound quality. Rich. Lush. Powerful. A music lover’s answer to spiraling cost-no-object equipment without sacrifice. In the more than forty years of PS Audio’s design innovations and breakthrough products, Stellar’s groundbreaking level of performance as our gateway standalone DAC and preamplifier is unmatched for price and performance by their standalone competitors. Taken together, we’re willing to bet you’ve never heard anything quite this good at anywhere even remotely close to this price.

The preamp

At the heart of the Stellar Gain Cell is its analog preamplifier section called the GainCell, a unique approach to solving a classic problem for preamplifier designers, the volume control. All preamplifiers must provide a means for the volume level to be turned up or down. Typically this is accomplished by inserting a mechanical or electronic element in the signal path which degrades the musical signal to some degree. PS Audio's unique GainCell solves the sonic losses associated with classic volume controls by using a different technology known as a variable gain amplifier. Instead of adding additional circuitry to the signal path to vary loudness, the preamplifier’s actual amplifier stage varies its gain in response to the user’s front panel volume control. This method requires zero additional circuitry in the signal path, thus eliminating the need for additional circuitry that loses musical information. Stellar’s GainCell's sound is rich, full and engaging in ways few preamplifiers can claim. From the quietest micro-dynamics to the loudest macro-dynamic passages, Stellar’s GainCell outputs gorgeous music through either its balanced or single ended outputs or its headphone amplifier. Music takes on new life through the GainCell.

The DAC

The DAC inside the Stellar GainCell will transform your expectations of what’s possible in resolving all of music's nuance and splendor without a trace of digital harshness. The DAC itself is based on the acclaimed 32-bit ESS Sabre Hyperstream architecture, the output of which is passively filtered to reduce transient distortion. The DAC's output stage is a unique Class-A configuration, fully balanced and direct coupled hybrid array, with an extended bandwidth of -3dB at 60 kHz feeding directly into Stellar’s analog GainCell. The GainCell DAC features a high-resolution USB path based on the same XMOS technology found in our DirectStream DAC, as well as our exclusive I²S inputs featuring a separate clock and data signal from the source. I2S outputs are sent via an HDMI cable and I²S compatible sources can be purchased from PS Audio as well as other manufacturers. We believe that one audition of a simple CD, played through the Gain Cell DAC, will open your eyes to the magic these design efforts have brought. And once you hear what the Gain Cell DAC does on ordinary CDs, we can’t wait for you to hear what the Gain Cell DAC can do for higher resolution PCM and DSD.

INDUSTRY

The PS Audio Stellar Preamp and S300 Amplifier are a couple of the most musical components I’ve heard in a long time, especially in solid state, and especially in this price point. What we’re really looking for from our hard-earned dollar is the enjoyment of our music and if this were my current market, I would snatch these two components up in a heartbeat. PS Audio continues to impress me with their products, their service, and their attention to detail. The Stellar Gain Cell DAC has certainly forever changed my viewpoint on what a good DAC can do, and I encourage you to audition this for...

All PS Audio components I’ve encountered (or owned) are incredibly well-built and the Stellar line is no exception. They have a weight, look and feel that exudes quality belying their sub-$5,000 USD total cost and puts me in mind of gear I’ve reviewed costing double this price point.

The PS Audio Stellar ‘three-fer’ proved itself to sound far more captivating, powerful, lyrical, musical and possess a humanity to its sonic signature in playback of all types of music than I previously thought a preamplifier and mono blocks priced under $5,000 USD would be capable of. They would, without fail...

“…I could not fault the sound of the Gain Cell DAC -- its neutrality and honesty were captivating, leading to compelling listening. During my time with it and the pair of M700s, I always felt they had total control over whatever music was thrown at them, in whatever format. From the understated nuance of an unaccompanied lute to the bombast of a symphony orchestra going full tilt, the laid-back drive of dub or the pulse of electronica, I not once felt deprived of any of the music’s emotion, rhythm, dynamics or detail. Whether using planar, stand-mounted or floorstanding speakers, I knew I...

Speaking of price, there's nothing about the Stellar Gain Cell DAC/Preamp that says under $2k. This holds for the music it makes which is really great news. Based on my experience, albeit time-worn, I get the impression that PS Audio likes to make music sound highly listenable through its products. You know, the way we want it to sound. The Stellar Gain Cell DAC/Preamp commits no digital crimes against music. It is smooth, well-balanced, and eminently listenable… The preamplifier, as advertised, is very good sounding and there's no reason not to mate Stellar with your amp-O-choice. Again...

They sounded so good together I couldn't bring myself to try too many other speakers. The sound was rich with resolution to die for.
Magnepan speakers aren't known for their deep bass punch, but here with the two Stellars the .7 speakers' low bass was kicking with "The Legendary Skatalites in Dub" reggae album with really low, feel-it-through-your-toes bass. Austin Wintory's orchestral score for "The Banner Saga" sounded downright huge, and the low bass drums definition was truly stellar!

that's its greatest strength: the Stellar Gain Cell DAC allows you to seamlessly, transparently switch between sources, increase gain, and make meaningful sound adjustments, all the while calling zero attention to itself. This unit is not merely a DAC with a volume control: it's the ideal analog preamplifier, and the fact that it includes PS Audio's idea of trickle-down engineering in the form of an affordable, nearly world-class, budget-friendly DAC is the icing. The GCD is a keeper—it comes very highly recommended!

The headphone amp section of the Stellar DAC appears to build on that device. So let's call it an improved version of the GCHA (originally $999), with far lower output impedance for better compatibility. Then throw in a PS Audio NuWave DSD for the DAC section (which is still in their catalog at $1299), making sure to tweak a few things for improved performance. At this point we've already far surpassed the $1699 asking price for the Gain Cell DAC, and that's not even counting the superb analog preamp section designed specifically for this device.

Let me just cut to the chase. The Stellar exceeded my expectations for sound quality in nearly every respect. The digital inputs produced gobs of detail, great dynamics, proper soundstage, and wide frequency range. Ripped CDs and hi-res downloads sounded astoundingly good via USB input played by my player of choice, Channel D’s Pure Music, on my Macbook Pro. Plus, the analog inputs sounded clean, full, and lively. Exactly like I hoped they would!
There’s no way around it, this is one hell of a lot of value packed into a single chassis. And the sound is as good or better than you are going to..

It is rather amazing to consider how much excellence PS Audio has managed to squeeze into this one product. Would you get better sound, say from a standalone DAC that costs as much as the Stellar? Possibly, but you’d still need to buy a preamp to go with it. And chances are, one with similar flexibility and performance as the Stellar’s won’t be available on the cheap. Factor in the excellent headphone amp section and it’s hard to argue with the appeal and value of the Stellar.

If your system already comprises top-notch gear, this may not represent a significant improvement over the existing..
