Audio46's Opinion
The iDSD Valkyrie delivers an exceptionally smooth and distortion-free sound, even at high volumes. The combination of high-resolution playback, customizable sound modes, and powerful amplification ensures that it can drive even the most demanding headphones with ease. Testing the Valkyrie with high-end headphones like the Abyss JOAL and Dan Clark E3, it proved powerful enough to rival desktop amplifiers.

- JVCKENWOOD's K2HD Technology
- DSD 1024 Remastering
- Four Burr-Brown DACs
- Up to 5,700mW Max. Output
- Lossless Bluetooth
- xMEMS Support
- USB-C Fast Charging

A Mastering Suite. In Your Hand
The iDSD Valkyrie isn't just powerful - it's personal.
Designed for those who seek musicality andemotional depth, it lets you sculpt the feel of yourmusic with technologies once exclusive to theworld's best mastering houses - empowering you tobecome your own remastering engineer.
Winged Wonder.
The front plate design of the iDSD Valkyrie is inspiredby the majestic wings of the Valkyrie's horse.
DSD Remastering
The iDSD Valkyrie is designed intently for those wanting tosculpt the feel and emotion of their music, to exactly howthey envision it.
Inspired by the artistry of mastering engineers, it featuresour bespoke DSD1024 Remastering algorithm, poweredby a custom-coded FPGA.
Similar to the technology used in Sony's masteringstudios, DSD Remastering transforms any file byincreasing resolution and reducing distortion - deliveringsound that rivals a professionally remastered recording.
The History of K2
Born from the legendary Victor Studios, this technologywas created to breathe life and emotion back intodistinctly clinical sounding digital audio.
To achieve this, JVCKENWOOD engineers analysedthousands of original masters at Victor Studios, fine-tuningK2's parameters guided purely by their own humanexpertise and intuition.
Once exclusive to JVCKENWOOD, this remarkabletechnology now resides within the heart of the Valkyrie,ready to be experienced at the press of a button.
K2HD Technology
The Valkyrie incorporates two modes; 'K2' mode and'K2HD' mode.'K2HD' optionally upscales audio files to 192kHz/24-bit before applying selected K2 parameters forprecise waveform shaping.
It extends high frequencies to restore naturalharmonics, achieving sound quality close to theoriginal master.
For those who prefer restoration without changingthe sample rate, 'K2' mode provides a similar effectwhile preserving the file's original resolution.
The Finishing Touch.
Alongside these powerful technologies, the Valkyriealso offers six digital filters, letting you fine-tune thedetails and craft a listening experience that's trulyyour own.
- Bit Perfect
- Standard
- Minimum
- GTO
- Apodising
- Transient Aligned
Perfect Your Headphones.
Complementing its digital customisation suite, theValkyrie features analogue processing that transformsheadphone listening into a captivating experience.
- Enhances the audio by creating a spacioussound field
- Adds back the lost bass frequencies from openheadphones
- Pushes mid presence towards the listener, formore forward sounding vocals
Quad-DAC Architecture
At the heart of the Valkyrie are four Burr-Brown DACs ina hybrid multi-bit configuration, drawing inspirationfrom our long-standing experience with the legendarymulti-bit Philips TDA1541A.
First introduced in the Pro iDSD, this interleaved designcaptures the magic and impact of the iconic multi-bitchipset, but with superior low-level linearity forbreathtaking detail.
Cut the Cord. Not the Quality.
Bluetooth used to mean sacrificing quality forwireless convenience. Not anymore.
As pioneers of Lossless Bluetooth, we've equippedthe Valkyrie with the latest technology to deliver CD-quality audio wirelessly, with zero data loss.
It also supports genuine Hi-Res Bluetooth playbackover LDAC and LHDC.
Next-Gen Compatibility.
xMEMS is a cutting-edge driver technology for IEMsthat uses the piezoelectric effect to deliver lightning-fast, accurate sound.
The Valkyrie provides the correct bias voltage andequalisation* required to optimally drive xMEMS IEMs.
- Some 150x faster than mechanical drivers
- Virtually no phase shift
Colossal Battery Capacity.
To power all its advanced features, the Valkyrierequires a serious battery configuration.
Lift the hood, and you'll find four batteries,combining for a colossal 20,000mAh.
Not only do batteries provide the cleanest powersource, but they do so with enough life to last aflight from London to New York… and back.
That's up to 18 hours on a single charge.
Rapid Recharging.
Get back to enjoying your listeningsessions without any long waits.
Valkyrie's impressive fast-chargingcapability, allowing you to fullyrecharge in just 2.5 hours.
It supports the latest USB-C PDstandards and is QC3.0 certified at 20V.
Powered by Battery or Mains
High-capacity 20,000mAh lithium-ion batteries provide long runtime despite extreme amp power.
iPowerX power supply with Active Noise Cancellation.
Design Philosophy
"At iFi, we create products that blend technology with emotion. We view our products as both precise tools and musical instruments; enabling you to hear music the way it was meant to be heard, with all the emotion it conveys.
The Valkyrie, our high-end portable DAC, merges timeless design with innovative functionality. Its shape evokes the spirit of bygone era and its legends; the SR-71 Blackbird and early sports cars.
Every surface is carefully considered for optimal sonic, visual, and tactile enjoyment:
- CNC-machined aluminium for flawless fit and finish
- Retro champagne anodisation with satin finish for a timeless aesthetic
- Solid aluminium buttons and an oversized control knob, inspired by a watch crown
- Gorilla glass display for scratch-resistant durability
Valkyrie is more than just a DAC; it's a gateway to rediscovering music in all itsemotional depth."
