The Pro iDSD Signature is our new flagship reference and much more, it is both a DAC, preamplifier, network streamer and headphone amplifier with exceptional sound quality.
The Pro iDSD Signature uses a quad DAC in an interleaved configuration to deliver exceptional resolution.
The powerful XMOS XU216 X-Core 200 series chipset processes the incoming digital data and enables the Pro iDSD Signature to offer 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 DSD remastering to a wider audience. It can convert PCM and DSD files to DSD512 and DSD1024.
The Pro iDSD Signature has a darker sonic backdrop and more punchy bass. Its power supply system has been improved to reduce overall system noise by 300% by incorporating our acclaimed iPOWER Elite external power supply as standard.
Unlike other amplifiers that have the same circuit and only switch the tube section, the original Pro iDSD and now the Pro iDSD Signature are among the first to have two individual input circuits: one tube (General Electric 5670 tubes!) and one solid state. The result is the "best sound of both worlds".
The amplifier's audio circuitry is totally discrete, fully balanced, with switchable tube or J-FET input, bipolar second stage and bipolar Class A power stage with MOSFET damping.
We have given the Pro iDSD Signature an additional Tube+ setting. This reduces overall loop gain and negative feedback to a minimum and presents a different sonic perspective between natural tube harmonics and transient performance.
The Pro iDSD Signature is packed with premium components: a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps "super capacitors".
The Pro iDSD Signature, like its predecessor, takes sonic tailoring to the extreme. Listen to your music in your choice of solid-state, tube or tube+ modes at the flick of a switch.
Our Crysopeia FPGA digital engine strikes again, allowing the Pro iDSD Signature to offer several options when it comes to digital filtering. The GTO filter adds gravity and a new dimension, while the Bit Perfect, Bit Perfect+, Apodising and Transient Aligned filters give you even more options for fine-tuning your sound.
The Pro iDSD Signature employs the new 16-core XMOS XU216 X-Core 200 Series processor. All digital processing is Bit-Perfect unless particular digital filters are explicitly selected.
Data is sent to the memory buffer from all inputs. Here it is de-jittered to eliminate any jitter transmission from the source to the DAC output. The data in the memory buffer is re-synchronised to the low jitter Global Master Timing® clock, which also drives the X-Core 200 and the FPGA.
The discrete, fully balanced Class A amplifier stage offers adjustable gain.
All inputs are galvanically isolated (including USB). The USB input section has its own power management system with multiple regulators and filtering operating from the galvanically isolated voltage generated to power this section.
Stream wirelessly from Tidal, Spotify, Napster, QQ Music and more.
Use Airplay to enjoy playback from your iPhone, iPad or Mac.
Connect via wired Ethernet connection to playback from a router or NAS (Network Attached Storage). Use DLNA network audio playback with smartphones, tablets and Windows/Linux computers. Connect to a hard disk drive (HDD). Insert a USB stick or Micro SD card.
With integrated WiFi/network playback LINKPLAY, Spotify and Tidal, and extensive protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD Signature can also be used without a computer to stream audio directly.
The iFi iDSD Signature offers a variety of headphone outputs: Single-Ended 6.3mm, S-Balanced 3.5mm and Balanced 4.4mm making it compatible with the vast majority of headphones on the market.
And all controlled from the included remote control or via a free downloadable app for smartphones or tablets.
