MSB The Cascade Dac (Black With Matte Stainless Accents)

An all-new rethinking of digital reproduction.

The 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.

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.

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.

Bit Diffusion Technology

Bit Diffusion Technology was invented by MSB’s Chief Circuit Designer, Dustin Symanski, while working on the forthcoming Sentinel DAC project with astounding results.  Adapting this into the Cascade DAC with a minor hardware update, the result is much more than a small tweak! It is a significant, technological step forward in musicality, resulting in wonderfully natural playback. Dustin’s concept for BDT was initially sparked by considering the relationship between an atom and an electron’s probability density function. Mimicking this natural phenomena, Bit Diffusion is applied to the Cascade’s unique architecture of 16 independent DAC channels. Low-level ambient noise and digital artifacts are diffused, adding to analog-like sound and a much more relaxed, fatigue-free presentation. Listening to that one recording you know and love so well, thinking you knew every detail, it is shocking to then hear so many new nuances and beautiful moments washing over 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.

A clean source

The Cascade Powerbase builds on our extensive experience with power supplies for critical analog circuitry. AC power is often polluted with interference from local computers, lighting, and appliances. This is why we have added an additional layer of protection with internal AC filtering that acts to significantly reduce this interference. To increase performance, we have three higher VA custom wound transformers that are electrically and magnetically shielded. After being converted to DC by discrete silicon carbide rectifiers, the raw power is then filtered by new optimized banks of inductors and capacitors to remove the majority of the residual noise from the raw DC. This is then regulated by our discrete, ultra-low noise linear power supplies. The five individual power rails are output for use by the Cascade Analog Converter.
