A Signature step up

The Signature takes the original Pro iDSD and pushes it even further towards perfection. It has a darker sonic background and punchier bass, upgraded power supply components for 300% lower system noise, matched NOS GE5670s tubes, USB1.0 support for PS4/PS5, a new aluminum remote, and the premium iPower Elite power supply included.

E-tailoring

The Pro iDSD Signature offers extreme sonic tailoring with solid-state, tube, or tube+ modes at the flick of a switch. The Crysopeia FPGA Digital Engine provides multiple digital filtering options, including GTO, Bit Perfect, Bit Perfect+, Apodising, and Transient Aligned filters, for precise sound tweaking. Its fully balanced Class A amplifier stage features adjustable gain.

Stacked. With tech.

The Pro iDSD Signature uses a quad-stack DAC – 4 x DACsin an interleaved configuration – to deliver exceptional resolution. The powerful XMOS XU216 X-Core 200 series chipset processes incoming digital data and enables the Pro iDSD Signature to provide state of the art audio support – from MP3, 32-bit/768kHz PCM, DSD512, 2xDXD and full MQA decoding. Thanks to the Crysopeia FPGA Digital Engine the Pro iDSD Signature brings studio grade DSD remastering to a wider audience. It can upconvert PCM and DSD files to DSD512 and DSD1024. And all controlled from an app in the palm of your hand.
