iFi Audio 0303021 iDSD Valkyrie Portable DAC Headphone Amp (0303021)

iFi Audio 0303021 iDSD Valkyrie Portable DAC Headphone Amp (0303021)

The iFi Audio 0303021 iDSD Valkyrie is a flagship portable DAC/amp that brings studio-grade DSD Remastering and JVCKENWOOD K2HD Technology to everyday listening. It transforms any file with higher resolution and lower distortion to aim for sound that rivals a professionally remastered recording, while delivering powerful headphone drive and flexible wired or lossless Bluetooth playback.

DSD Remastering and K2HD processing

A custom-coded FPGA powers iFi’s bespoke DSD Remastering, like the technology used in Sony’s mastering studios. By increasing resolution and reducing distortion, the Valkyrie works to deliver sound closer to a professionally remastered recording.

• Professional-grade DSD1024 Remastering
• JVCKENWOOD K2HD Technology restores rich, natural harmonics
• Advanced high-frequency extension revives overtones beyond 22kHz
• User-selectable ‘K2’ and ‘K2HD’ modes, plus six additional digital filters

Quad-DAC architecture for detail and separation

A quad-stack of Burr-Brown DACs in a hybrid multi-bit configuration underpins the Valkyrie’s clarity. This mastering-grade design achieves unmatched linearity and impeccable channel separation, delivering the dynamic punch and slam associated with legendary multi-bit chipsets alongside superior low-level linearity for breathtaking detail.

• Four Burr-Brown DACs mix eight pairs of differential signals
• Design legacy from iFi’s Pro iDSD and inspiration from the Philips TDA1541A
• Analogue path on a dedicated board to minimise crosstalk

Headphone power and control

The iDSD Valkyrie integrates an extraordinarily powerful headphone amplifier for demanding listening.

• Up to 5,700mW maximum peak output
• Balanced 4.4mm and 3.5mm headphone connectivity

Wireless and digital connectivity

Qualcomm’s flagship QCC518x platform enables lossless Bluetooth and high‑resolution wireless playback. For wired sources, the Valkyrie accepts USB‑C and S/PDIF (Coaxial/Optical) inputs, and it offers full xMEMS support.

• aptX Lossless with a maximum 1,200kbps bitrate for CD‑quality audio without losing data
• LDAC and LHDC/HWA support for up to 96kHz/24‑bit audio
• Bluetooth 5.4, plus USB‑C and S/PDIF inputs
• Full xMEMS support

Analogue sound tailoring

Beyond digital filters, the Valkyrie includes iFi’s signature analogue processing to customise playback.

• XBass II reinstates missing bass for open‑backed headphones or recordings that crave a bass boost
• XPresence adds midrange presence
• XSpace restores an expansive soundstage

Battery capacity and silent power

Four 5,000mAh lithium‑ion batteries total 20,000mAh, providing up to 18 hours of playback on a single charge. Battery operation keeps the signal free from electrical interference and noise, and the included SilentPower iPowerX enables mains use at noise levels 20x quieter than most audiophile power supplies.

Frequently Asked Questions
