## Metrum Acoustics DAC3 - Next-Generation R2R Upgrade Modules
**Double the Performance of Your Metrum Device with This Plug and Play Module Upgrade!**
The next generation of Metrum Acoustics digital-to-analog conversion technology is here. The DAC module is the core of our digital to analog converter products and is the upgrade you've been waiting for!
### What DAC3 Delivers
DAC3 effectively doubles the amount of R2R ladders with respect to the DAC2 transient modules. This fundamental advancement brings several audible improvements:
- **Tighter, More Defined Bass:** Output impedance is lower, leading to more precise and controlled low frequencies.
- **Laser-Accurate Imaging:** The placing of instruments can be spotted with laser accuracy. Space between instruments increases while the visceral impact of your entire setup increases in a defined way.
- **Enhanced Micro-Detail:** While adding more R2R ladders and IV stages, linearity is improved, leading to more audible micro details and that sense of: "I have never heard that in a recording I know so well."
Guaranteed listening pleasure while listening to all your recordings again...
### Compatibility
All Metrum DAC power supplies are fully capable of powering DAC3. The following modules are required for plug and play replacement in these Metrum Acoustics DACs:
| Model | Modules Required |

| [**Adagio**](/product/adagio) / [**Pavane**](/product/pavane) (Level 2 or higher*) | 8 |
| [**Jade**](/product/jade) / [**Onyx**](/product/onyx) | 4 |
| [**Amethyst**](/product/amethyst) | 2 |
| Musette | 2 |
| Pavane Level 1 (after in-factory modification*) | 8 |
| Menuet (after in-factory modification) | 4 |
*Flint is not recommended for DAC3 upgrade*
Please note, DAC3 is sold per piece, where [DAC2](/product/dac2) is sold as a set of 2 pieces.
### Installation
When upgrading and placing the modules, please note that the dot on the DAC module aligns with the dot on the main circuit board. See the Attachments section for placement instructions.
For those with Flint or Musette DACs, consider the [**DAC2 Transient modules**](/product/dac2) as your upgrade path.
