Selling my Metrum Onyx R2R DAC.
Balanced NOS DAC using 2x DACTWO transient chips per channel. Upgrade your home sound system. With the goal of creating a mid range and affordable, yet superior DAC in mind Metrum Acoustics designed the ONYX. 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 FPGA driven R2R ladder networks as used in the 4x DACTWO modules performs on a higher level. These modules split 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 R2R ladder DACs. The result of this process is an extremely high linearity, right down to -145 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 realised. This contributes to the flawless positioning of instruments.
In short, the ONYX is a DAC that has taken all the lessons and experiences that Metrum Acoustics has learned over the years, and combined them in an ambitious DAC that can fit in every system. It is musical, honours the Non-oversampling principle while simultaneously incorporating the technological progress that has been made over the years.
Comes with box power cable and remote control.
The item being advertised is sold "as is", and no warranty should be assumed unless otherwise indicated and agreed between the Buyer and the Seller. Photos representing the item being advertised form part of the description unless otherwise specified.
Prices vary significantly by condition: new or mint units command premiums near original MSRP equivalents, while used examples in good to excellent condition sell for 60–80% of that due to the product's 8+ year market presence and limited recent listings.
Key factors affecting value include:
- Condition and age: Pristine, low-hour units with original packaging fetch higher prices; cosmetic wear or repairs reduce value by 20–30%.
- Region and currency fluctuations: Original prices were ~NZ$4,200 (2017, roughly AUD$4,000–4,200 then) or €2,062+ (about AUD$3,300+), with AUD estimates adjusted conservatively for inflation and exchange rates.
- Accessories and provenance: Inclusion of remote, original box, manual, or upgrades (e.g., I²S/USB modules) adds 10–20%; provenance from reputable sellers boosts appeal.
- Market demand and rarity: Low production volume and high-end NOS R2R appeal sustain value, but sparse recent used listings on global sites indicate softer secondary market liquidity.
These estimates are conservative due to outdated search data (pre-2026); actual prices may vary—check current platforms like HifiShark for listings.
