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
Test samples can be found on our website and downloaded for
playback and testing.
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.
