DCS Lina Headphone Amp
No one knew exactly what to expect from dCS Data Conversion Systems' first separate analog power amplifier, but neither is anyone surprised by the excellence of Lina headphone amplifier anyway.
Stereophile's extensive review saw Lina pitted against flagship competition and emerge with distinction ... "watch out for goosebumps, tears and laughter, because that's how you'll know if they can please for the long haul".
Exhibiting remarkable specs on paper, it's immediately apparent how Lina's discrete transistor solid-state reference amplifier product translates those into spectacular audible results – an analog product that proves worthy of bearing the dCS name. [See Product Desc. For More]
A pinnacle of frequency extension and transparency, Lina headphone amplifier makes its case to be the ultimate, final headphone source you'll ever need – conjuring macro and micro dynamics before your ears while always sounding relaxed and completely natural in its tonality.
READ ALSO How Lina is the perfect amp for Susvara
When fed by dCS' accompanying Lina network DAC, Lina amp's fully-balanced, differential design encased in solid aluminium brings out even more than you thought your flagship headphones could produce.
Headfonia didn't do a very good job, trying to prevent their jaw from dropping at Lina's performance. From "planar headphone fan" Headfonics, "this is a tremendously satisfying and engrossing world-class solid-state amplifier". Lina saw Headphone Guru's headphones replace his speakers over a month of testing.
READ ALSO Lina – designing the perfect voltage source
She was a Hi-Fi News Outstanding Product. Lina amp outputs in excess of 4 watts with enough current-handling ability for loads like the Abyss AB1266 Phi TC, Hedd Audio HEDDphone and HIFIMAN's Susvara. At the drawing board, dCS invest every effort in building Lina amp as a linear open-loop design.
READ ALSO Building a dCS statement in analog design
Rather than achieving current-handling capability via the usual technique of building with more output transistors in parallel, Lina amp opts for quality over quantity and a lower parts count.
Less is more, and dCS elegantly selects fewer but more unconventionally capable devices with 8 ampere current capability exceeding the normal needs of headphone amplifiers.
Feeding this potent array of beastly power transistors is a proprietary driver stage that dCS designed to operate linearly with low open-loop distortion, unfazed by pushing the large output devices.
This secret voltage gain circuit is more than up to the task of passing along and upsizing the signal of Lina DAC transparently without adding noise and distortion, thanks in part to cascodes operating supplementary and reducing voltage-induced non-linearities.
READ ALSO Lina power quality matters – not just quantity
Said cascodes also play a part reducing capacitance at the bases of transistors where they operate, which provides tremendous high-frequency performance with Lina amplifier extending out to 100Khz at -3dB.
Meanwhile, Lina amp's DC-coupled nature also means bass extends down to subterranean levels – this kind of frequency performance down low and up top guarantees superbly flat phase reproduction in the audible human hearing range for potent and realistic musical dynamics. Through the audio microscopes that are flagship headphones, Lina's perfect phase response is undisputedly audible.
The above – low output impedance, excellent current-handling, low distortion and frequency extension – all remarkably achieved in the open-loop. After getting these basics of an excellent analog circuit right, dCS then apply the cherry on the cake – closing the loop with negative feedback to make an already good design great.
dCS thus achieves the amplifier ideal of a straight wire with gain, adding as little colouration as possible to let your transducers speak freely, to the fullest of their potential.
It's been thoroughly thought out. When used with Lina DAC, Lina amp takes advantage of the former's high-current line-stage. The latter boasts an unbuffered balanced input, bypassing unnecessary active input stage devices and simplifying the circuit further for less chance of error.
Now we see – with the gargantuan task of creating a standalone amplifying product that lived up to the dCS name, these digital specialists pulled off a masterclass in analog design. A true testament to the skill of the designers, for the benefit of the most dedicated headphone listeners.

DCS Lina Network DAC
The Lina network streaming DAC boasting Ring DAC technology is both a continuation and a new beginning for dCS Data Conversion Systems.
Lina DAC's design combines renowned dCS technologies with new innovations developed for headphone listeners – resulting in a bold new interpretation of the dCS experience, and a complete re-imaging of form and function alongside Lina headphone amp and Lina master clock.
READ ALSO The inside story behind Lina DAC's creation
What doesn't change, however, is a level of new immersion, resolution and realism that accompanies any dCS; even at Lina's new entry-level point. There are multiple ways to get your music aboard Lina DAC, with Spotify and Tidal Connect, plus Roon Ready status, standing by for easy connectivity right from set-up.
With Lina DAC, dCS took core playback technologies, including the dCS Ring DAC and Digital Processing Platform, and added new innovations developed for headphone listeners. [See Product Desc. For More]
5 ⭐ came from What Hi-Fi?. Headfonia didn't do a very good job, trying to prevent their jaw from dropping at Lina's performance. Lina's "energy, dynamics, and a very strong level of detail retrieval" floored Headfonics. It saw Headphone Guru's headphones replace his speakers over a month of testing. She was a Hi-Fi News Outstanding Product. These impressive results translated to speakers too, for Steve Huff.
A sensible flex-ridged circuit board allows dCS to deliver all of the features you’d expect from a dCS DAC in a much smaller chassis that would sit handsomely on a desktop or coffee table.
READ ALSO The exhaustive breakdown of dCS Ring DAC technology
At the heart of all dCS DACs is the Ring DAC, and Lina is no different. Ring DAC denotes a proprietary digital-to-analog conversion system.
Ring DAC is renowned for its ultra-wide bandwidth, technical accuracy, and ability to reveal astonishing levels of detail in digital recordings – from the subtlest of sounds, to the sense of time and harmonic movement, and the atmosphere that surrounds a musical performance.
A Xilinx Artix-7 FPGA comes loaded with the dCS Ring DAC mapping algorithm, and custom dCS oversampling linear-phase filters. FPGA technology allows dCS to supply constant firmware updates with time, by way of network updates.
This showcases Lina's status as a true software product with each firmware upgrade yielding audible and functional improvements that sees dCS DACs always stay relevant.
READ ALSO Software-driven hardware design at dCS
After digital signal processing at Lina DAC's FPGA, the oversampled signal is then processed by a high-performance array of resistors and current latches controlled by the Ring DAC mapping algorithm, to form the basis of Lina's supreme performance discrete delta-sigma DAC.
Designed from the ground up by dCS, not relying on performance-limiting off-the-shelf DAC chips, there is literally nothing out there like Lina DAC.
Lina gives all listeners the capability to expand its potential beyond a single box – its high-current discrete analog line output stage, fully balanced and differential – is designed to preserve the transparency of the Ring DAC.
It can feed directly the unbuffered input section of Lina headphone amp, for full resolution and best signal-to-noise ratio.
Lina master clock meanwhile sits alongside ready to supply a reference clock source via dual BNCs for Lina DAC. Pushing phase noise and jitter far below audibility, the difference Lina master clock makes is profound, even on a decoder already as supreme as Lina DAC – and must be heard to be believed.
The result is a powerful, supremely capable product designed for use in a wide range of environments, from living rooms to studios and workspaces.
With its wide dynamic range, crisp, clear playback, expansive soundstage, and tonal neutrality, Lina DAC provides a deeply natural, highly detailed, and profoundly musical sound that encapsulates our singular approach to audio.
Add unique headphone optimisation technology like digital crossfeed, an elegant and tactile design, and a high-performance streaming platform, and you have a hugely versatile source that delivers spectacular sound, however you choose to listen.

DCS Lina Master Clock
The Lina master clock is a product inspired by dCS Data Conversion Systems' absolute dedication to achieving the highest possible standards of sound reproduction.
Headfonia didn't do a very good job, trying to prevent their jaw from dropping at Lina's performance. Lina saw Headphone Guru's headphones replace his speakers over a month of testing. She was a Hi-Fi News Outstanding Product.
Design of Lina clock, to operate in tandem with Lina network DAC connected by dual BNCs, is informed by dCS experience developing master clocks for professional and home use. Headfonics clearly heard an improvement, certainly in a way he didn't miss Rossini clock.
READ ALSO Lina a timely addition to dCS heritage
Designed to further suppress jitter and phase noise in Lina DAC, it uses two oven-controlled crystal oscillators to deliver a precise and stable clocking reference for all audio formats and frequencies. [See Product Desc. For More]
When paired with Lina DAC, Lina clock allows its sibling's internal clock system to be locked to a master signal, for even greater precision and enhanced audio performance.
READ ALSO The scientific basis of dCS master clocks
Its standalone design ensures sensitive clocking components are protected from factors that can cause interference. Each crystal oscillator is oven-controlled to ensure its performance remains consistent, even under changing conditions and temperatures.
With its own dedicated chassis and power supplies, clock signals are thus protected from power interference, crosstalk and other factors that can affect integrity and in turn, audio quality.
The feedback dCS received from listeners and audio experts who’ve experienced significant sonic benefits after adding such a master of time to their system clearly advised their design for the most thorough headphone reference rig available to market.
Designed for maximum reliability and longevity, Lina clock is a silent but powerful component engineered to operate with absolute precision and consistency, so you can experience the best possible performance from your system.
Combined with the rest of the Lina system that you can view here, Lina clock delivers an even more profound and immersive dCS listening experience, and helps ensure the audio you hear sounds exactly as it should.
