Metrum Acoustics Onyx

Metrum Onyx (Black) with I2S connection- NO USB

***I do have the USB module if you want to install USB (pics included)

The I2S connection is where the "USB" port is on the back

I used for just over a year and was purchased directly from Metrum Acoustics

I used this with Metrum Ambre and It was fantastic, but moving to an all in one  (streamer/DAC) solution.

"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."
