Flux Atlas is the outcome of 10 years of experience designing High-End audio equipment and 2 years of continuous development of this model only. Happy to present our flagship DAC/preamp/headphone amplifier!
Smart ergonomics
This device is equipped with a touch screen, a digital encoder, a motorized volume control and an infrared port (used along with the remote control) to control all the functionality. The front panel is made of solid aluminium milled on a high-precision five-axis milling machine (SMC Machine)
Flexibility
Taking an attention wide number of digital interfaces on market and customers traction for an experiment Flux Atlas equipped with all necessary digital interfaces. To provide the best sound quality there are realised two separate outputs of the DAC and pre-amplifier, AUX input. Trigger out socket and micro-USB update port.
The Atlas digital-analog part is built using two best-in-class converters made by Asahi Kasei Microdevices – AK4497EQ. These converters have a lower level of non-linear distortion and have a noticeable superiority in dynamic range as compared to the previous generation. A dual mono circuit with one separate AK4497EQ chip per channel is used to ensure the maximum dynamic range and channel separation.
4 independent low-noise linear regulators are used for each chip including a separate core power supply taking into account the relatively high dependence of AK4497EQ on the power supply quality.
The power supply module circuitry includes capacitors of Fine Gold series manufactured by Nichicon and tailored to audio devices. The use of these capacitors allows you to get a clearer sound in the entire frequency range and, in particular, a magnificent low-frequency range.
The signal of each AK4497EQ is filtered by an individual low-pass filter (LPF) developed entirely on a discrete-component circuit. The choice of such a complex decision is conditioned by the fact that only the use of certain radio parts which cannot be located inside single-chip devices (an operating amplifier) makes it possible to obtain a noticeably better result. The LPF circuit uses resistors made by the Japanese company Takman Electronics which are designed for the use in audio devices. Installing them in a discrete-component circuit of LPF allowed us to obtain an exceptional level of naturality and softness of the sound which is challenging or even impossible to achieve using the “factory-made” metal-film resistors and most surface-mounted resistors (SMD).
Amanero Technologies software is used for integrated USB converter. It is arguably one of the best solutions for the output of a digital stream from USB in asynchronous mode. The USB connector is additionally isolated from the chassis of the device by means of an anti-short bushing. This minimizes the parasitic capacitive coupling between the USB connector that connects to the PC and the DAC case which is connected to the analog ground.
All digital signals at the output of the USB converter are galvanically isolated from the board on which the AK4497EQ digital-to-analog converters are installed. This solution prevents the transmission of digital noise from the PC and prevents the formation of a parasitic circuit (an “earth” loop). As a result, it is possible to get the maximally clear sound of the system in any situation.
Clocking the digital part is carried out from ultra-low-noise generators manufactured by Crystek Corporation – CCHD-575. It allows achieving exceptionally stable and accurate operation of the digital part of the DAC circuit.
Raspberry Network Core. The Flux Atlas can link wirelessly or directly to a router for network music playback. With, and wide protocol support for 32-Bit/192kHz and DSD128, the Flux Atlas can be also used without a computer to stream audio from any network device or USB-drive.
Being a true balanced circuit design the Flux Atlas built on a premium Japan Alps motorized rotary volume potentiometer with 4 tracks.
An Oyaide single-crystal copper cable made in Japan is used for internal analog wiring layout.
The preamplifier/headphone amplifier is built entirely on a basis of balanced layout for which four identical amplifier units are used. Amplifiers operate in deep class A that allows gently transmitting the smallest peculiarities when playing audio recordings.
The amplifier circuit has three basic amplification gain factor setting options (GAIN) for matching with headphones with various impedance and sensitivity.
Only high-quality connectors are used to connect external devices. RCA connectors are manufactured by CMC and AC-INLET Furutech. XLR and headphone 6.3mm outs made by Neutrik.

At $3,400 with unknown condition, this Atlas asks an ambitious price given its $4,995 MSRP—used examples in very good shape have surfaced around that original figure recently, but expect $3,000-$3,800 for clean units with full kit on the secondary market. It's no steal unless pristine and low hours, as Flux's reference gear holds value but softens with age in a niche market dominated by bigger names.
Before biting, verify the touchscreen and motorized volume respond smoothly—early Atlas units have shown encoder glitches under heavy use—and confirm all accessories: original remote, power cable, and manual. Probe usage hours via the service menu if possible, and insist on biased listening to check for class-A heat signatures or channel imbalance, as these balanced amps can develop subtle offset issues over 2-3 years.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Atlas Cables emerged from Scotland's vibrant hi-fi scene in 2000, rooted in the expertise of industry veteran John Carrick, who developed value-driven cable lines for the British retailer Mountain Snow in the 1990s. A group of five dealers acquired the brand in 2003, rebranding it as Atlas Scotland Ltd. and propelling its growth from those early successes. Today, headquartered in Kilmarnock, Ayrshire, the independent UK-owned company designs and handcrafts nearly all its products on-site, embodying a quarter-century commitment to Scottish engineering precision.
The brand specializes exclusively in high-performance cables and accessories, spanning interconnects, speaker cables, digital links, power cords, and specialized components like tonearm cables. eschewing amplifiers, speakers, or source gear in favor of eliminating signal loss between system elements. Their philosophy distills cable design to five essentials—conductor, dielectric, connector, screening, and manufacturing—using premium materials such as Oxygen Free Copper (OFC) and superior Ohno Continuous Cast (OCC) variants for open, accurate, natural sound.
Atlas holds a respected niche in the high-end market as a boutique specialist, earning global acclaim through award-winning lines like Mavros and Asimi, distributed in over 30 countries. Knowledgeable audiophiles value its no-nonsense, hand-built quality that punches above its price, positioning it as a go-to for system upgrades without hype or excess.
