iFi iDSD GR 2: High-Res Portable DAC with Wireless Support
iFi has announced the iDSD GR 2, a portable digital-analog converter (DAC) priced at $529. According to the company, the device features a Burr-Brown PCM1795 chipset, supports PCM 768 kHz and DSD512, and utilizes JVCKenwood K2HD processing to restore high-frequency detail in compressed audio files.
How does the iDSD GR 2 handle high-resolution audio?
The iDSD GR 2 uses a Burr-Brown PCM1795 chipset to enable lossless PCM 768 kHz and DSD512 decoding, iFi reports. This hardware allows the device to process extremely high-sample-rate audio files that exceed the capabilities of standard smartphone or laptop internal DACs.
Power output is a primary focus for this model. iFi states the DAC delivers 1,513 mW RMS of power (peaking at 2,173 mW) into 32 ohm headphones. This level of amplification allows the portable unit to drive demanding over-ear headphones that typically require a stationary desktop amplifier.
Why is JVCKenwood K2HD processing significant for streaming?
Most streaming services use “lossy” compression, which strips away high-frequency data to reduce file size. iFi says the integrated JVCKenwood K2HD processing restores the depth, tone, and musikalitet (musicality) lost during that compression process.
This technology targets the gap between convenient streaming and audiophile-grade playback. By reconstructing missing elements, the iDSD GR 2 attempts to make Spotify or YouTube audio sound closer to a lossless FLAC or WAV file.
What wireless codecs does the iDSD GR 2 support?
The device supports high-resolution Bluetooth audio via aptX Lossless, LDAC, and LHDC codecs, according to the company’s specifications. It also maintains compatibility with standard SBC, AAC, aptX, and aptX Adaptive codecs.
The inclusion of aptX Lossless is a specific nod to the industry shift toward “CD-quality” wireless audio. While traditional Bluetooth compresses audio, these newer codecs aim to deliver bit-perfect audio over the air, reducing the need for physical cables without sacrificing fidelity.
How does the hardware design impact usability?
The unit is controlled via a color OLED touchscreen, though iFi provides further fine-tuning and OTA (over-the-air) updates through the iFi Nexus app for Android smartphones. The device measures 141 x 75 x 19 mm and weighs 268 g.
Battery life is rated for up to 7 hours of playback, powered by a 4,900 mAh lithium-polymer battery. iFi states the device requires 3.5 hours for a full charge.
