Designed for those who seek musicality and emotional depth, it lets you sculpt the feel of your music with technologies once exclusive to the world’s best mastering houses.
Remastering content to high resolution DSD has previously only been available to a select few, including the world's best mastering houses.. The Valkyrie brings this once exclusive processing to the hands of the consumer via a custom-coded FPGA, to transform any file and ultimately make music sound closer to a professionally remastered recording.
K2HD restores rich, natural harmonics to lifeless digital recordings. Its advanced high-frequency extension revives overtones beyond 22kHz, delivering audio quality close to the original master. We worked with JVCKENWOOD for 18 months to develop this product and bring their renowned K2HD Technology back to the forefront.
Negative feedback is used in amplifier circuits to compare the output signal with the input signal and correct errors. BUT there are drawbacks. iFi turns the negatives into positives with OptimaLoop. Read more below.
Powered by quad-stack of Burr Brown DACs, the Valkyrie achieves unmatched linearity and impeccable channel separation – a design legacy from our mastering-grade DAC, the Pro iDSD. Inspired by the legendary Phillips TDA1541A which is hailed as the ‘king of multi-bit DACs’, this quad-core DAC architecture echoes the magic and heritage of the Philips chipset used inside the AMR CD-77. The Valkyrie offers the dynamic punch and slam of the iconic Phillips chip, but with superior low-level linearity for breath-taking detail.
The iDSD Valkyrie boasts an extraordinarily powerful headphone amplifier, capable of delivering up to 5,700mW of maximum peak output, measured our way. For more information on how and why we measured the Valkyrie using our own standards, please refer to
The iDSD Valkyrie is for those demanding more than pure power or precision; it’s for those who seek the power to sculpt the feel and emotion of their music. Fusing sonic customisation with cutting-edge technology, the Valkyrie hides thunderous amounts of sonic control, with K2HD Technology, DSD Remastering, six additional digital filters, and our signature analogue processing. Complete with quad-DAC architecture, 5,700mW* peak output, lossless Bluetooth, and 18hours of battery life, it is unmatched by any other portable.
Inspired by the artistry of mastering engineers, the Valkyrie features our bespoke DSD Remastering algorithm, powered by a custom-coded FPGA. Like the technology used in Sony’s mastering studios, DSD Remastering transforms any file by increasing resolution and reducing distortion, with the aim of delivering sound that rivals a professionally remastered recording.
These powerful technologies can be combined with six user-selectable digital filters, giving you more ways to experience your favourite music and discover the best for your ears.
Complementing its digital customisation suite are our all-analogue, renowned XBass II, XPresence, and XSpace processing modes:
aptX Lossless: 1200kbps
LDAC: 990kbps
aptX: 352kbs
SBC: 328kbps
We’ve equipped Valkyrie with the latest Bluetooth technology, courtesy of Qualcomm’s flagship QCC518x chipset and the aptX Lossless codec.
Offering a maximum bitrate of 1,200kbps, aptX Lossless is the first and only Bluetooth codec currently capable of wirelessly sending CD-quality audio without losing data.
For those wanting high-res Bluetooth playback, the Valkyrie also supports 96kHz/24-bit audio via LDAC and LHDC/HWA codecs.
The iDSD Valkyrie has other innovative, next-generation technologies up its sleeve – including full xMEMS support.
To power all its advanced features, the Valkyrie requires a serious battery configuration. Under the chassis lie four 5,000mAh lithium-ion batteries, totalling a colossal 20,000mAh.
Not only do batteries provide sound free from electrical interference and noise, but they do so with enough life to last up to 18 hours of playback on a single charge – lasting a flight from London to New York… and back.
For those moments when you need to use mains, the Valkyrie comes with a SilentPower iPowerX, operating at 20x quieter than most audiophile power supplies.
