Design
The thing about design in the audiophile world is that it becomes fairly easy to tell if something is high-end. The high-end design does not just mean a high price tag, but rather that it’s made with premium components, quality materials, and a keen understanding of how these things go together in a package that looks worthy of what you pay for it. DCS is synonymous with elegance and modernity. They’re not gaudy or industrial-looking like some audiophile equipment can be, but rather it’s an understated external chassis design that has just a brush of suave - enough to show off the fact that it takes a lot of planning and precision engineering to make a chassis this smooth and sleek. I’m a big fan of the Rossini design. Sure from afar you can mistake it for just another CNC aluminum-milled box, but it’s not until you get right up to it that you see the elegance that only dCS can accomplish. The wave pattern on the top of the front face sets it apart from the lower-tiered Bartok series.
On the front of the Rossini DAC, you'll find a display screen to the left on the faceplate, followed by the power button, the Menu button, Filter, Input, and Mute buttons. On the right side of the front face is the navigation and volume wheel, allowing you to make your selections in the menu and adjust the volume output as needed.
The back of the DAC is where the real fun is, however, providing the user with a multitude of inputs and outputs. On the left side, you'll see balanced (XLR) and single-ended (RCA) stereo analog outs, followed by 2 AES/EBU inputs, 3 SPDIF jacks (RCA, BNC, and Toslink), 2 wordclock inputs, 1 wordclock output, USB Type A, USB Type B, 2x Network/Ethernet ports (Main and Loop), RS-232 Connection (Crestron, AMX RTi, URC, Control4), and the power switch. The Rossini provides an outstanding I/O suite for any hi-fi system out there, allowing you to integrate this world-class DAC for top-of-the-line conversion.
Available in silver or black finishes, the Rossini Apex is designed to complement any high-end audio setup while making a statement of its own. But the Rossini's beauty isn't just skin deep. Every aspect of its design serves a purpose, from the carefully chosen materials to the precise placement of each component. This marriage of form and function is a hallmark of dCS's design philosophy, where nothing is superfluous and everything contributes to the ultimate goal: unparalleled audio reproduction. The Rossini's chassis is a testament to dCS's commitment to excellence. Constructed from aerospace-grade aluminum, it's not just about looks – this robust enclosure serves a critical function in isolating sensitive internal components from external vibrations and electromagnetic interference. The chassis is precision-milled to incredibly tight tolerances, ensuring perfect fit and finish. This level of precision serves multiple purposes. First, it creates a visually stunning product that exudes quality. Second, and more importantly, it provides a stable and inert platform for the delicate electronics within. By minimizing external influences, the Rossini ensures that the only thing you hear is the music, reproduced with utmost fidelity.
Peek inside the Rossini, and you'll find a layout that's as much a work of art as the exterior. The internal architecture is a study of optimal signal path design and component isolation. Critical analog and digital sections are physically separated to minimize interference, with careful attention paid to power supply routing and grounding schemes. This meticulous internal design is crucial to the Rossini's performance. By keeping sensitive signal paths as short as possible and isolating potential sources of noise, dCS engineers have created an environment where each component can perform at its absolute best. The result is a vanishingly low noise floor and exceptional clarity across the entire frequency spectrum.
Heat is the enemy of precision electronics, and dCS has addressed this with an innovative passive cooling system. Carefully designed heatsinks and ventilation pathways ensure optimal operating temperatures without the need for noisy fans, preserving the Rossini's silent operation. This approach to thermal management is a perfect example of dCS's holistic design philosophy. By eliminating fans, they've not only reduced potential sources of noise but also removed moving parts that could potentially fail over time. The result is a product that runs cool and quiet, ensuring consistent performance for years to come. It's the small details that elevate the Rossini from excellent to extraordinary. The precision-damped feet minimize vibration transfer, the carefully chosen and positioned screws ensure rigid construction without introducing resonances, and even the silk-screened labels are designed for clarity and longevity. These seemingly minor elements add up to create a product that feels as good as it sounds. From the satisfying weight of the unit to the smooth action of its controls, every interaction with the Rossini reinforces its quality and craftsmanship.
Creating each Rossini is a painstaking process that combines high-tech manufacturing with artisanal craftsmanship. From the initial CNC machining of the chassis to the final assembly and testing, each unit undergoes rigorous quality control checks. dCS employs skilled technicians who hand-assemble critical components, ensuring that every Rossini meets the company's exacting standards. This blend of cutting-edge technology and human expertise is what sets dCS apart. While machines ensure precision and consistency, it's the trained ear and experienced hand of a skilled technician that provides the final stamp of approval. Each Rossini is not just assembled; it's crafted with care and attention to detail that borders on obsession.

Sound
-dCS
The heart of the dCS Rossini is its proprietary Ring DAC, a testament to dCS's commitment to audio excellence. Unlike many manufacturers who rely on off-the-shelf components, dCS builds its Ring DACs entirely in-house, allowing for unparalleled control over the digital-to-analog conversion process. To appreciate the significance of this approach, it's essential to understand the fundamentals of digital audio conversion. Sound in its natural form is analog - continuous waves of air pressure that our ears interpret as music or speech. To store and manipulate audio digitally, these analog waves must be converted into digital data through a process of sampling and quantization. The quality of digital audio is primarily determined by the sample rate (how often the analog signal is measured) and bit depth (how many binary digits are used to represent each sample).
When we play back digital audio, we need to reverse this process, converting the binary data back into an analog signal that can drive our speakers or headphones. This is where a Digital-to-Analog Converter (DAC) comes into play. A DAC's primary function is to translate binary numbers into corresponding analog voltages, using a series of current sources - electronic components that generate specific amounts of analog voltage based on the digital input. Traditional DAC architectures, such as ladder DACs, face several challenges including component tolerances, zero crossing point distortion, and linearity issues, which can result in various forms of distortion potentially compromising the purity of the audio signal.
The dCS Ring DAC takes a fundamentally different approach to digital-to-analog conversion. Instead of using a fixed ladder of current sources, it employs a large number of identical current sources arranged in a ring configuration. Rather than assigning each bit to a specific current source, the Ring DAC dynamically maps the digital signal across its array of current sources. This mapping changes constantly, following a complex algorithm. By spreading the conversion across multiple current sources, the Ring DAC effectively averages out small errors in individual components. The dynamic nature of the conversion process helps to minimize issues like zero crossing distortion and improves overall linearity. Before the actual D/A conversion, the Ring DAC employs sophisticated digital signal processing to upsample the audio and shape the noise spectrum, pushing quantization errors out of the audible range.
This unique architecture offers several advantages. By averaging across multiple current sources, the Ring DAC achieves a level of precision that's difficult to match with traditional architectures. The dynamic mapping and advanced signal processing help to minimize various forms of distortion, resulting in a purer audio signal. The Ring DAC maintains its accuracy even at very low signal levels, crucial for preserving the subtle details and ambiance in music. As a proprietary design, dCS can continually refine and improve the Ring DAC through both hardware and firmware updates, allowing existing products to benefit from ongoing research and development. In essence, the dCS Ring DAC represents a groundbreaking approach to digital-to-analog conversion, addressing many of the challenges inherent in traditional designs and aiming to deliver the utmost fidelity to the original audio signal, allowing listeners to experience their music with unprecedented clarity and realism.
dCS' Ring DAC seeks to correct the issues that are inherent in ladder DACs. The Ring DAC uses a network of FPGAs (field programmable gate arrays) that run proprietary dCS software that performs digital-to-analog conversion and digital filtering. A couple of things to note about the Ring DAC that make it different from a ladder DAC. A key point here is that the ladder DAC removes the link between the original signal and the physical resistor value errors associated with specific sample values.
- The Ring DAC uses current sources of equal value
- The Ring DAC does not use the same current source(s) for the same bit every time
One of the key advantages of the Ring DAC is its upgradeability via firmware updates. Featuring DXD upsampling as standard, the Ring DAC's multi-stage oversampling design offers optional DSD upsampling plus an extensive selection of DSP filters to suit individual tastes and music choices. You've got four filters with DSD content, plus six filters with PCM. I played around with PCM filtering and found the differences to be subtle, with Filter 4 offering a discernible lift in warmth and fullness to the sound.
If 1080p is the standard for high-definition video today, 4K is the premium version, 8K is still a ways off, then the Rossini APEX is easily the 16K of the future. We've talked about "realism" before here in reviews, but it's like you don't know how far something can go until you've heard the next best thing, right? That's the case with the Rossini. The Bartok and the Lina all sound end-game (as they should), but the Rossini is another game entirely. It's on another plane of existence in comparison. Details abound, and there's something about the "tone" of rings DACs that I really like the more I listen to them. It's hard to explain, but it's an extremely subtle element that makes the recordings feel a touch more organic. Perhaps it's the nature of dCS products in general, but there's a level of transparency and musicality that stands out.
I'll be honest - I'm obsessed with this setup (see the Dragon cable section for a full list). I used it in the Auris Audio Headonia Review, and I doubt I'll find a replacement for some time. Yeah, it's a pricey one, but the Rossini is at the top of the totem pole so it's hard not to go all out. Abbey Road is one of those albums that I know better than the back of my own hand. With every instrument entrance, harmonies, backing parts, flubs, and more, it's one of those handful of albums I use to instantly discern the sonic abilities of a piece of gear. On Here Comes the Sun, there's a gentle and sweet element of the acoustic guitar that usually gets lost in lesser systems once the rest of the band comes in after the intro. The Rossini helps sustain this tonality of the guitar throughout the rest of the arrangement, partly due to the excellent soundstage and imaging that it provides. There is a musicality to Paul's bass playing that comes to the forefront this time around. It equally drives the tune and there's a lot of dancing around notes that the Rossini is bringing out beautifully.
The Battle from Hans Zimmer's Gladiator score has been featured numerous times in my reviews in the past. It's an endurance and dynamics test that I like to put new gear through to assess overall performance. Soft lows to bellowing highs, sub bass that easily distorts the driver - it is not a test for the faint of heart and for systems not truly up to the task. It was no issue for this setup. The Rossini Apex, combined with the Master Clock, Headonia, and the Susvara Unveiled was simply the best I have ever heard this score sound. There are few moments in this hobby where you simply have to stop and admire what is coming into your ears. This was a top 5 experience for me, and the number one spot for The Battle. I've never heard it this encompassing, impactful, full of emotion and energy. I'm one of those people who get goosebumps when listening to music (apparently a rarity according to statistics), and my skin was crawling the entire 10-plus minutes from start to finish. The shine on the brass, the warmth of the French horns, and the thundering drums are something every audiophile should experience on this earth. The Rossini + clock combo is especially capable - delivering extremely fast and dynamically stable. The HiFiMan Susvara Unveiled is a superb headphone for this setup and sound, but I tried others including the Meze Audio Elite and the Dan Clark Audio E3 with equally exciting variations on a theme.
The sense of space and distance is something that stands out to me about the Rossini Apex. No matter the size of the ensemble, whether it be a small jazz trio, an eight-piece ska band, or a symphonic orchestra, the sound that comes from this set (the Rossini Apex and the Master Clock) is wonderfully dynamic according to the recording. The trio still fills up the room, but what helps fill in the space is provided by a sense of intimacy and proximity, being able to localize each performer and your proximity to them. Larger ensembles sound like so, but there is space provided for each performer, each section, with incredible third-dimensionality. I wish I could compare this to a non-Apex Rossini to see how much is improved with dynamics, tonal balance, soundstage, and resolution, but after listening to the Rossini Apex for the duration of this review, there's really no need. Once you hear something at this level of fidelity it's going to be hard to compare. The bar is set, and the Rossini Apex and Master Clock is the real end-game deal.

Clocking: A Closer Look
-dCS
dCS pioneered the use of external master clocks in the 1980s, and they've been perfecting their expertise since then. Now, you may wonder: "Why would I need an external clock? Doesn't the Rossini Apex DAC already have a clock?" It does. Every DAC contains a clock, but adding an external master clock to your system can result in significant sonic improvements. Subjective listening tests have shown improved imaging, resolution, dynamic expression, and localization, plus a greater sense of rhythmic movement and flow when you use a master clock. So while the Rossini Apex DAC delivers great performance, adding the Master Clock improves the sound quality when using the network or USB inputs. Does not having an external clock mean you can't enjoy your music? Of course not. But when you are trying to squeeze out every last drop of performance, adding one is the next upgrade.
Any digital component must have a clock to understand when it's time to do something with the audio samples it receives at its input. Clocking is like a "drill sergeant" that keeps digital files aligned along their time axis. This is not just limited to the DAC chip, if one is used, but also the other digital signal components that have to keep in line with the digital-to-analog process (digital power supplies, control chips, and other various pieces of the digital puzzle).
The timing of this process is crucial to ensuring the audio we hear provides an accurate representation. If audio samples aren't converted by the DAC at exactly the right moment, then we hear an artificially distorted version of the musical note. If the timing fluctuates during the digital-to-analog process, it is much more difficult to render an analog audio waveform that is identical to the original. This is even more critical with DSD audio signals over PCM, as they function at megahertz speeds in the time axis. Having as accurate a clock signal as possible is crucial for the re-creation of digital audio signals, particularly high-resolution files that use ultra-high sampling-rates, such as DSD at 22.5MHz or PCM at 768kHz.
The DAC must convert the signal at an exact moment in time along with its other partners in the signal path. Let's say we have a standalone CD transport and a standalone DAC. Each one of these devices has all sorts of components that need to line up with the data stream. Now, all off-the-shelf DAC chips have their own ability to do some clocking, and crystal clocks are implemented a lot of the time, but this only controls what is happening in that device. But when multiple devices are in the digital chain, you need more.
Think of jitter as digital noise. It doesn't sound as drastic as, say, pink or white noise in the background, but what it does is smear the tonality of the music ever so slightly. The result might be less resolution and clarity. It's like looking through dirty eyeglasses: You can still see, but not as clearly. Digital clocks have very sensitive circuitry. And like anything else in the audio equipment realm, if you isolate functions of the process into its own device, you can do a much better job of isolating that one function.
Here is an easier way to explain this in the analog domain. Let's say you have an audio receiver. At one time, the audio receiver did it all. It had a tuner for radio, a preamp for volume control and switching, a phono equalization circuit, and an amplifier for the speaker. If you isolate each one of these pieces into its own chassis with its own power supply and filtering and so on, each one of these pieces can do so much better on its own and sound better than if they are all combined in one circuit. Now that is not to say that you can’t build a good all-in-one, but it is more complicated. If we can separate out the clock and have it control each digital device's timing, the lenses in those eyeglasses become ultra-clear and sharp. A clock circuit is very sensitive to interference and especially temperature. Temperature in a multi-circuit device like a CD player is not easy to control; there are just too many circuits and processes going on.
The Rossini Clock introduces a dual frequency output and auto-clocking mode, technologies previously seen in dCS's flagship Vivaldi series. These features significantly improve ease of use while minimizing jitter, a critical factor in maintaining audio fidelity, especially when dealing with computer audio sources. Flexibility is a key attribute of the Rossini Master Clock. Its output configuration can be optimized to accommodate a wide variety of digital audio sources, making it a versatile addition to diverse high-end audio setups. The clock's multi-stage regulation system effectively isolates sensitive clock and PLL circuitry from digital interference, preserving the purity of the timing signals. Housed in an aerospace-grade machined aluminum chassis, the Rossini Master Clock isn't just about internal excellence. The exterior is fitted with tuned acoustic damping panels, which work to reduce magnetic effects and vibration, further enhancing the clock's performance and the overall audio experience. The dCS Rossini Master Clock goes to extreme lengths to guarantee stability and reliability whether you are doing internet streaming or pulling stored music from your network. If you want the best performance for your high-resolution audio on your Rossini music streamer, then the Master Clock is a necessity giving you complete control and ensuring absolutely no aliasing in your hi-fi setup.
Software - dCS Mosaic
Mosaic at a Glance
Mosaic is dCS' proprietary software that allows you to browse and play music from any device running iOS or Android. Mosaic consists of three elements:
dCS Mosaic is the name for the audio streaming and networked control functionality of dCS products.
dCS Mosaic Control is the name of the iOS and Android software application for music management and product control.
dCS Mosaic Processor is the physical hardware component and associated software that is installed in the dCS product to provide streaming functionality.
dCS Mosaic is a bespoke collection of hardware and software modules that allow you to access your digital music in various formats. When it comes to controlling your music library, a well-executed app can make the experience that much more seamless and pleasurable. The dCS Mosaic app for iOS and Android offers an intuitive way to browse and access music from multiple sources and audio libraries. Mosaic brings together audio from multiple sources into a single, unified interface, making multi-source playback simple. You can use the app to browse media from various streaming services and to manage settings and configuration options for your dCS products. Mosaic is compatible with:
- UPnP
- USB
- Internet Radio
- TIDAL, Qobuz, Deezer Hi-Res Music Streaming Services
- Spotify via the Spotify Connect app
- Podcasts via Airable
Since the Rossini Apex is Roon Ready, you have the option of using Roon as your media management platform. If you have a Roon account, install Roon Core on your NAS drive or on a networked computer. You can then use Roon remote to control playback on your Rossini Apex. Why might you opt to run Roon instead of Mosaic? It comes down to user experience – and your willingness to pay a monthly subscription fee.
Roon was created for the music streaming enthusiast who wants a highly curated experience. It's a virtual playground for music discovery, where you can spend as much time researching as you do listening. Now, Roon offers the basics like album info, artist info, and track info. But Roon takes it many steps further with things like extensive artist bios, artist suggestions, and lots of visual pizzazz. The home screen in Roon is a personalized experience with personal stats, recent activity, suggestions, playlists, and more. One thing to note is that you can't access internet radio through Roon like you can with Mosaic.
Mosaic offers a more streamlined, minimalist user experience. A great thing about Mosaic is that it's a custom code developed by dCS that can be upgraded and enhanced over time. Neither Roon nor Mosaic is the better choice; it all comes down to user preference. And it's great to have the option to use either.
