Eight Hybrid DACs.

With eight Hybrid DACs, we yield an unmatched level of detail, reproducing the musicality, soundstage, and texture of an original performance, bringing the artist to you. A fully balanced, ultra-high precision, discrete ladder DAC architecture ensures each note tells a story. Additionally, MSB’s robust in-house design enables the finest quality playback of PCM and native DSD, while our low impedance circuitry drives your amplification directly without adding coloration or buffering noise. The end result is a digital experience defying expectations.


Femto 33 clock.

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. Each Reference DAC comes with the our most advanced Femto 33 Clock featuring a custom oven controlled dual crystal design.


The Select powerbases.

Two dedicated power supplies provide increased isolation and electrical performance for both the digital and the analog power. With the increased space, each Select Powerbase has a much lower electrical noise design.


Completely modular.

Paired with performance increases, our modular design ethos increases flexibility for future updates and product support, guaranteeing a long-term product investment. As you pursue higher levels of playback, an MSB upgrade path is always available to help drive your own desire for innovation. Whether it’s a software update or a leading-edge modular component, we’re here to help the most valued aspect of MSB—our customers.


The last preamp you will ever need.

The Preamp Output Module will give you a cutting edge constant impedance passive volume control preamp.  Using this remarkable preamp will reduce system complexity and ultimately improve the audio quality of your entire system.  It’s a remarkable feat of electrical design that sets a new benchmark in the industry. The output modules are individually tuned for maximum quality balance or single-ended audio. With sideways expansion, the preamp can accommodate additional analog inputs, isolated sub outputs, and extra analog outputs.
