Ehrmantraut Posted November 8, 2019 Posted November 8, 2019 Item: iFi Audio Pro iDSD Professional tube/Solid-State DAC/Headphone amplifier - As new condition Location: Brisbane - Express post to all states included Price: $2799 ono - all offers considered, please PM me Item Condition: As new - about 30 hours of use Reason for selling: NLR - I may regret this. I combined with iCAN Pro for planars and it's a great sound. Hugely adaptable DAC and MQA decoder. As my experience grows, I've upgraded my HeadFi system.

Big ones, little ones, balanced ones… The Pro iDSD now currently comes in two ‘balanced’ versions – with 4.4mm or 2.5mm balanced headphone sockets. You choose which version you need. So, whatever your mood, however you connect or listen, the Pro iDSD has an option for you. The Pro iDSD 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. The Pro iDSD employs the new XMOS XU216 X-Core 200 Series 16-Core processor. All-digital processing is Bit-Perfect unless particular digital filters are explicitly selected. Explore the XMOS…. Upsampling to DSD1024 has previously only been available to a select few. The Pro iDSD 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. Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA. 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. With LINKPLAY™ WiFi/network playback, built-in Spotify and Tidal, and wide protocol support for 32-Bit/192kHz and DSD64, the Pro iDSD can be also used without a computer to stream audio directly. 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. Unlike other amplifiers that have the same circuit and just switch in/out the tube section, the Pro iDSD is the very first of its kind 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’. We’ve given the Pro iDSD 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. 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. The Pro iDSD is packed full of premium components – a Japan Alps rotary volume potentiometer, audio-grade ELNA Silmic capacitors and a bank of Elna Dynacaps ‘super capacitors.

Ehrmantraut Posted November 8, 2019 Author Posted November 8, 2019 I know - perfectly partnered with iCAN Pro.....I'm upgrading to Auralic Vega G1 and Luxman 750...hope I'm not making a mistake!
Ehrmantraut Posted November 9, 2019 Author Posted November 9, 2019 PS - I’m taking delivery of Luxman 750 this week, so will be posting my iCAN Pro in similar condition to the iDSD listed above. If you’re thinking about a combo deal (they’re made for each other!) then PM me thanks....
Ehrmantraut Posted November 12, 2019 Author Posted November 12, 2019 Tuesday bump - any takers on both iFi's? Combo deal?
Murray Hodges Posted November 14, 2019 Posted November 14, 2019 SOLD to me. Thank you @BlueOceanBoy I will be making payment today. 1
