iFi micro – iDSD Black Label USB DAC Headamp
|The iFi micro iDSD Black Label is the newest iFi micro flagship product.At the heart, beats the Burr-Brown DSD512/PCM768/2xDXD True Native® DAC with headphone amplifier.
The Black Label looks very good on the outside yet the inside is even better where relentless attention has been paid to advancing the sonics with the very latest components:
|• DAC digital signal and digital power sections upgraded
• AMR Global Master Timing® femto-precision clock system upgraded for ‘super low’ phase-noise/jitter
• Analogue signal and power sections revised
• 3D ® performance-tuned / XBass ® performance-tuned
• Latest Output stabilisation network offers less distortion
The micro iDSD BL retains the unrivalled technical capabilities of its predecessor. This means it is capable of true native playback of all music formats from MP3 all the way up to 512DSD/768PCM/2xDXD.
The Burr-Brown DAC chip used was one of the last chipsets from BB Japan (though it was introduced post-merger). This chipset was Burr-Brown’s ‘swansong’ and embodied all their converter technology. It is unrivalled in terms of subjective musicality and is a mainstay of the iFi line including the micro iDSD Black Label and is used in the upcoming showstopper, the Pro iDSD.
The latest iterations of 3D and XBass are appreciated technologies that further enhance the enjoyment of music. With a larger soundstage and deeper, tighter bass respectively, both are even more engaging and satisfying than ever.
iFi/AMR ‘OV’ series stands for ‘Operationsverstärker’ (German for Operational Amplifier). The ‘OV’ range IC’s use HCOFC copper lead-frames and 4N Gold bond-wire which are streets ahead of mainstream commercial chips that use inexpensive aluminum bond-wire, low-grade/low-cost copper in the lead-frames.
It is seldom found because it requires the custom packaging of chips from wafers and has a very high MOQ (30,000 pcs per part and purchase) to do – a small insight into the parts used in the micro iDSD BL which are ‘above and beyond.’
Os-Cons, originally from Sanyo (now taken over by Panasonic), have been around for a good while. Among the larger value capacitors useful in power supplies, they hold a special place. They have been used in AMR components up to the revered CD-77 Reference Class CD Processor.
There are three power output modes, Eco, Normal and Turbo. If used in conjunction with the built-in iEMatch, the micro iDSD BL is able to have the power and gain dialed-in to perfectly suit all headphones from the super-sensitive Sennheiser IE-800 up to the hyper-hungry HiFiMan HE-6.
Digital Audio Players (DAP) and home SPDIF sources are abound. Flexibility remains key and the micro iDSD BL retains the intelligent SPDIF in/out socket for optical/coax signals. So for those who wish to upgrade their DAP, simple use it as a transport and feed the micro iDSD Black Label.
From the very hungry HiFi Man HE-6 down to the Sennheiser IE-800, the micro iDSD Black Label is able to play hi-res out and about for 6 to 12 hours respectively. Even when not in use, it is able to charge an iPhone from 0% to 100% two times through its side USB charging port.
