Metrum Acoustics ONYX Balanced NOS DAC (Black)

Description

With the goal of creating a very affordable, yet superior
DAC in mind the designers of Metrum Acoustics have developed a new DAC, the
ONYX By Metrum Acoustics.

It was an unprecedented challenge, which was eventually
solved by using an entirely new chip, which has been exclusively developed by
Metrum Acoustics and was first used in the PAVANE.

The parallel driven R2R ladder networks as used in the four
DAC modules performs , especially when combined with our FPGA-driven “forward
correction module”, on a higher level. This module splits up the audio samples
for each channel into new separate data streams. Each dac cluster processes a
portion of the data in the most linear region of the dac chips. The result of
this process is an extremely high linearity, right down to -140 dB, which gives
the ONYX a realistic 24 bit dynamic range. Due to the dual mono design over the
entire frequency range an extremely high channel separation of 120 dB is
realized. This contributes to the flawless positioning of instruments.

In short, the ONYX is a DAC that has taken all the lessons
and experiences that her designer has learned over the years, and combined them
in an ambitious DAC that can fit in every system. It is musical, honors the
Non-oversampling principle while simultaneously incorporating the technological
progress that has been made over the years.
