The Audio-GD R2R-11 MK2 is a Swiss army knife for audiophiles. Combining the functions of a DAC, preamp and headphone amplifier, it will satisfy most needs. It features a discrete R2R NOS DAC, Amanero 384 USB interface, dual stage power supply, selectable digital filters and an MCU controller.
This version of the MK2 features several notable improvements designed to further enhance the musicality and sound quality of the unit.
Equipped with Amanero Combo 384 USB interface rather than USB32, it provides optimal performance and compatibility. It supports sample rates up to 32-bit 384 kHz PCM, as well as DXD and up to DSD512. Its design also allows it to have extremely low jitter.
The R2R-11 MK2 delivers optimal performance thanks to carefully selected components. So, in addition to supporting DSD / DXD and sampling rates up to 32 bit 384 kHz, it uses NFB (Non-Feedback) technology developed by Audio-GD at the ACSS stage. This allows the converter to provide less coloration of the sound and therefore accurate restoration, very low distortion and high linearity. This way you benefit from dynamics, detail and neutrality.
The R2R-11 MK2 features four discrete R2R DACs, two per DA-8 module, specifically designed and optimized for digital to analog conversion. They provide support for output sampling rates up to 32-bit 384 kHz and a signal-to-noise ratio of 100 dB.
