Product Description
The MSB Technology Cascade DAC
The MSB Technology Cascade DAC was born of an unwavering dedication to perfecting our craft, enabled by our enthusiasm for in-house design and vertically integrated manufacturing. This starts a new era—one built on twin foundations of innovation and experience. We began by reimagining the fundamentals of known DAC architectures from the ground up. Critical to the success of the Cascade DAC has been dividing the conversion process into three dedicated chassis and functions. First, all of the processing, sources, and interfaces that are necessary, but electrically noisy, have been concentrated in the Cascade Digital Director. Next, all of the critical low noise analog electronics have been housed in the Cascade Analog Converter. Finally, all of the analog power supplies have been moved to the dedicated Cascade Powerbase. This ideal component division enables sublime analog playback in nearly any system and listening environment. Let’s dive deeper into these building blocks to explore the industry leading technologies involved.
Part 1: The Digital Director
The Digital Director is the brain of the Cascade system, handling all the digital processes. It acts as an intermediary between digital players, transports, renderers, servers, computers, and the analog domain. It is able to identify, configure and process nearly any digital format with advanced new algorithms for faithful reproduction. It features a low noise linear power supply, elegant user controls, and a high visibility discrete LED display, along with user installable digital input modules. It then outputs a conversion ready signal over the fully isolated optical Cascade-Link to the Cascade Analog Converter. This allows you to easily place the Digital Director anywhere in your system with the reassurance that the analog processes are free of digital interference.
Recovering the recording
In order to push our audio technology even further, the Digital Director uses two high performance DSPs, each capable of sustaining 12 billion operations per second that work in tandem with two dedicated FPGAs. This is more than 4x the power of our previous generation of DACs. But that’s not all: advanced new digital filters, born from decades of research and development and tailored specifically for the Cascade DACs hardware, ensure that the Cascade DAC offers a superior, authentic reconstruction of the original analog signal. This increased processing headroom allows for a more expansive soundstage with even more beautiful textures from complex performances such as massed horns, vocals, close mic’d pianos, large ensembles, and full orchestras, regardless of the format. What emerges is the most natural and emotional presentation we’ve ever created.
The Cascade-Link
With modern digital technologies, such as servers, WiFi networks and LED lighting, it’s nearly impossible to create analog signals that are not only accurate, but also unpolluted and low noise. MSB developed many unique technologies in-house to make precision analog performances possible in any music playback setting. One of those vital and unique technologies is the Cascade-Link. Based on modern diode laser fiber optics, the Cascade-Link is a noise free, high bandwidth data river specifically designed to feed the insatiable hunger of the Hybrid DAC MKII’s in the Analog Converter without conducting any upstream electrical noise. It carries the raw, uncompressed data directly to the converter modules. This allows the Cascade DAC to produce an unmatched level of analog purity regardless of the environment it finds itself in. This is an industry-first technology that we believe will change the way digital and analog systems are designed hereafter.
A display for the listening chair
Equipped with high-visibility and a wide viewing angle, the display is both stunning and easy-to-read. This attention to detail demonstrates our love for functional and intuitive features. The LED display, which is slaved to the audio clock, is refreshed using the Femto Clock as the time reference, ensuring that your analog system is not polluted with any harmful digital noise created by the display. The in-house discrete design is then enclosed into its own shielded CNC pocket for optimal EMI isolation. Sit back and be immersed.
Part 2: The Analog Converter
If the Digital Director is the brain behind the Cascade System, the Analog Converter is the beating heart. With 8 New Hybrid DAC MKII modules, a Femto 33 MKIII Clock, passive analog stages, and 75 ohm volume controls, the Analog Converter makes the music come alive. Freed from the burden of any brute force digital processing, the Analog Converter is supremely adapted for the task of meticulous analog conversion. Digital music flows over the noise free Cascade-Link directly to the hybrid DACs, while stunning analog performances are received by the integrated analog inputs. All formats are carefully converted to MSBs unique fully balanced, constant impedance analog format. This enables an optimal connection directly to your power amplifier.
The Hybrid DAC MKII
A new generation of Hybrid DACs allow the Digital Director to extract the maximum resolution from all of your music files and from all data formats. As a fully balanced, ultra-high precision, discrete ladder DAC architecture, it reproduces all of the musicality, soundstage, and texture of the original performance. With 4X the DATA bandwidth of our previous generation, the Cascade DAC brings you reduced noise and improved resolution and linearity, ensuring that all the finest analog musical details are faithfully reproduced—bringing the artist to you.
Femto Clock MKIII
Our industry-leading Femto 33’s new Mark III configuration has been optimized for maximum performance with the Cascade DAC. Featuring two hand-tuned, ultra-low phase noise, oven controlled crystals that yield the lowest jitter for both the 44.1kHz and 48kHz digital format families. Our clock module architecture is built with the customer in mind—we’ve made the clock module user-upgradable, ensuring future updates are simple and streamlined.
Unrivaled analog performance
The moment an analog signal is created, it becomes vulnerable to irreversible degradation. To combat this, we have designed our analog stages to minimally affect the fragile analog signals they create. Balanced signals from the Hybrid DAC modules are passed directly to a completely passive, 75 ohm, constant impedance analog stage. They are passively attenuated and then immediately exit the XLRs without ever touching an amplifier of any kind. This preserves signal purity to the utmost degree while still enabling any cable, amplifier, or preamp to be optimally driven. Selection of each volume step is done by precious metal contact, latching relays whose coils are switched to ground when not active to avoid any signal corruption. Volume attenuation is done with distributed components so that no one precision part has too much power dissipation, thereby preserving the maximum linearity of the signal. The signal path is fully balanced and differential to prevent any ground currents from polluting the delicate signals.
