The Pro iDSD Signature is our new flagship reference class DAC and then some! The Signature edition builds on the strengths of the original, multi-award winning Pro iDSD.
It continues to cater for those who love good music delivered at the highest quality.
Use the Pro iDSD Signature as a standalone unit, a DAC/preamp, a network streamer and a headphone amplifier.
The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage.
We’ve given the Pro iDSD Signature an extra Tube+ setting. This reduces overall loop-gain and negative feedback to the minimum and presents a different sonic perspective between the tube’s natural harmonics and transient performance.
MQA (Master Quality Authenticated)
MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. The Pro iDSD Signature adopts MQA technology to receive and decode MQA audio and provide master-level sound.
Galvanic isolation is the ‘holy grail’ of computer audio.
All inputs are galvanically-isolated (including USB). The USB input section has its own separate power management system with multiple regulators and filtering operating from the galvanically-isolated voltage generated to power this section.
Data is sent to the Memory Buffer from all inputs. Here it is de-jittered to eliminate any transmission of source jitter to the DAC output. The data from the Memory Buffer is further re-clocked by the low-jitter Global Master Timing® clock, which also drives the X-Core 200 and FPGA.
The amplifier audio circuit is fully discrete, fully-balanced with either tube or J-FET input switchable, bipolar second stage and MOSFET-buffered bipolar Class A Power stage.
Upsampling to DSD1024 has previously only been available to a select few. The Pro iDSD Signature makes it available to a wider audience. The DSD1024 remastering is handled by the Crysopeia® FPGA and this is where we believe the FPGA excels.
With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD Signature can be also used without a computer to stream audio directly.
The Pro iDSD Signature has a ‘quad stack’ of Bit-Perfect DSD and DXD DACs by Burr-Brown. The ‘interleaved’ configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel.
Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the original Pro iDSD and now the Pro iDSD Signature are among the very first to have two individual input circuits – one tube (General Electric 5670 tubes!) and one solid-state.
This results in the ‘best sonics of both worlds’.
