iFi Audio iDSD GR2 MT Master-Tuned Ultra High-Res Portable DAC / Headphone Amp

iDSD GR2 MT - Ultra-Res Portable DAC + Headphone Amp - Master Tuned Series, by iFi Audio.

The iFi iDSD GR2 MT Master Tuned Series takes bleeding-edge portable audio and reimagines it through the ears of Grammy and Brit Award-winning producer Steve Levine.

Featuring component-level refinements throughout, this ultra-resolution portable DAC and headphone amplifier delivers the exact balance and emotional potency that define a legendary signature sound. Every sonic decision is guided by decades of studio experience, resulting in a listening journey that approaches the quality of original master recordings.

At the heart of this master-tuned device lies a Burr-Brown PCM1795 DAC chipset, enhanced by two exclusive digital filters specifically voiced for PCM and DSD playback.

The upgraded aerospace-grade hydrocarbon ceramic circuit board significantly reduces noise, providing a flawlessly clean foundation for the music. Coupled with audiophile-grade Tantalum resistors and Audio Note Kaisei capacitors in the amplifier stage, the system adds remarkable warmth and richness through the midrange while maintaining a dead-quiet, stable soundstage.

Despite its portable form factor, the amplifier section delivers a staggering 2,173mW of peak output power, easily driving the most demanding headphones.

Three distinct power modes, including the proprietary iEMatch technology, optimize the output for highly sensitive in-ear monitors. Wireless listening is equally uncompromised, featuring Bluetooth 5.4 with aptX Lossless technology for true CD-quality audio without data loss, alongside JVCKENWOOD’s K2HD technology for unparalleled harmonic restoration.

Navigation is seamless thanks to a vibrant 2.3-inch high-resolution TFT touchscreen display that offers quick access to on-board features and settings.

A robust 4,900mAh battery provides up to seven hours of continuous high-fidelity listening, complete with advanced battery health and hybrid power options to maximize long-term lifespan. Fully compatible with the iFi Nexis app for seamless updates, this portable powerhouse represents the pinnacle of critical listening on the go.
