iFi audio iDSD GR 2 MT Master Tuned Portable DAC & Headphone Amplifier

The iFi audio iDSD GR 2 MT takes iFi’s advanced portable DAC and headphone amplifier platform and gives it a specialized Master Tuned treatment developed with Grammy and Brit Award-winning producer Steve Levine. Built around the Burr-Brown PCM1795 DAC, the GR 2 MT features two exclusive Steve Levine digital filters—one optimized for PCM and one for DSD—along with carefully selected component upgrades designed to reveal greater depth, nuance, and emotional detail from your music.

Inside, an aerospace-grade hydrocarbon ceramic PCB with near-zero signal loss is paired with an upgraded OV4627A DAC I/V stage, audiophile-grade tantalum resistors, and Audio Note Kaisei capacitors in the amplifier stage. The result is a refined signal path engineered for exceptionally clean playback. With 1,513mW RMS of output power at 32 ohms, the iDSD GR 2 MT has the muscle to drive demanding headphones while retaining the control and low-noise performance required for critical listening.

For wireless listening, Bluetooth 5.4 supports premium codecs including aptX Lossless and LDAC, while JVCKENWOOD K2 and K2HD technologies help restore depth, harmonics, and nuance to digital recordings. A high-resolution 2.3-inch color OLED capacitive touchscreen places important settings within easy reach, while USB-C, optical, coaxial, Bluetooth, and analog connections make the GR 2 MT equally capable in portable and desktop audio systems. Hybrid power operation helps maximize battery longevity, and a dedicated desktop mode bypasses the internal battery when appropriate for a more permanent listening setup.
