The Heart of the System - Preamp and DAC
This product is a unique combination of a very high performance DAC and the ultimate passive preamp.
For the best possible sound in your system, it should be connected directly to your audio amplifiers.
Our preamp philosophy is based on the belief that from the moment analog audio is created, every
transition that is made degrades the sound quality. This is why we offer a passive preamp within the
DAC, to achieve the simplest, shortest possible signal path, with the least possible degradation of the
true music. The DAC's modular design is very flexible with the option for one or more analog inputs,
and many digital inputs. It is designed to be the last component in your system before the amplifiers
and replaces the need for a traditional preamp. The analog input can be enabled in the menu and
can be set to volume control the analog input or bypass the analog input if you want to use another
volume control for your analog source.

Loading new firmware

Always be certain that you are updated with the current firmware by checking our website. The DACs'
firmware is always updated using a .WAV file. If you experience issues with playback of the update file,
be sure to check for bit-perfect playback in your system.
All firmware updates can be found at:

Bit-Perfect Source Testing
The following files can be downloaded from the MSB website to verify bit-perfect playback on any
transport:
16 bit x 44.1 kHz sample rate file (CD standard).
16 bit x 48 kHz sample rate file.
16 bit x 88.2 kHz sample rate file.
16 bit x 96 kHz sample rate file.
16 bit x 176.4 kHz sample rate file.
16 bit x 192 kHz sample rate file.
They are .WAV test files that when played, will be identified by the DAC and checked, and will be
reported on the display if they are bit-perfect. If there is a problem with the test, it will play but the
display will not indicate any change. Be sure upsampling is turned off in any transport as this prevents
a file from remaining bit-perfect. This system will allow you to easily test your source, especially
computer sources, to see if all your settings are correct. There are files at all sample rates for both 16
bit and 24 bit operation.
24 bit x 44.1 kHz sample rate file.
24 bit x 48 kHz sample rate file.
24 bit x 88.2 kHz sample rate file.
24 bit x 96 kHz sample rate file.
24 bit x 176.4 kHz sample rate file.
24 bit x 192 kHz sample rate file.
