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.

Find Your Sonic Valhalla.

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.

The Valkyrie is built around four Burr-Brown DACs in a hybrid multi-bit configuration, drawing from our long-standing experience with the legendary multi-bit Philips TDA1541A. This design enables the mixing of eight pairs of differential signals to capture the magic and impact of the iconic multi-bit chipset, but with superior low-level linearity for breathtaking detail. To minimise crosstalk, the analogue path sits on its own dedicated board, isolated from digital components.

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.
