Review Summary

Ifi idsd signature is a great little gadget. It comes in portable format but has specs that can shame high end desktop audio setup with DAC and AMP. So far I have used it with earbuds as well as full sized cans like Sennheiser HD58X. Everything sounds phenomenal. Too much power on reserve. Very musical and natural sounding. I did not care much about the bass boost feature and 3D sound feature, but it does not obstruct anyway. If you can spend this much money, it is well worth it. I would like to compare it with chord MOJO 2 as it can be it's only competitor.

Discover the pinnacle of portable audio enhancement with the micro iDSD Signature DAC and Headphone Amplifier, a premium device designed to elevate your listening experience to celestial heights. Encased in a striking Space Blue finish, this top-tier desktop/transportable DAC and headphone amp is engineered to supercharge your music with unparalleled clarity and power.
At the heart of the micro iDSD Signature lies a custom 'interleaved' configuration of two Burr-Brown DAC chips, which work in harmony to deliver a quartet of differential signals - two per channel. This advanced setup results in a significantly lower noise floor, exceptional channel separation, and the revelation of intricate musical details and micro-dynamics. The device supports an impressive array of audio formats, including native playback of PCM up to 768kHz, DSD up to 512, 2xDXD, and MQA files, ensuring your audio remains 'bit-perfect' and true to the original recording.
Precision is the hallmark of the micro iDSD Signature, which boasts an array of jitter-eradication technologies. The GMT (Global Master Timing) femto-precision clock and intelligent memory buffer work in concert to ensure a pristine digital signal. Additionally, the pre-installed GTO (Gibbs Transient Optimized) digital filter further refines the audio output.
With an impressive output of up to 4100mW, the micro iDSD Signature confidently drives a wide range of headphones, from sensitive in-ear monitors to power-hungry planar models. The signal path is meticulously crafted to maximize sonic texture, utilizing high-spec components known for their low ESR, high stability, and minimal distortion. The absence of a coupling capacitor in the direct-coupled circuit underscores the device's commitment to delivering top-notch sound quality and musical enjoyment.
The micro iDSD Signature offers versatile sonic tailoring options to suit your personal listening preferences. The digital stage includes filter settings such as 'Standard', 'Minimum Phase', and 'Bit-Perfect' for PCM files, as well as 'Standard Bandwidth', 'Extended Bandwidth', and 'Extreme Bandwidth' for DSD files. The amplifier stage features three power and gain settings: 'Normal', 'Turbo', and 'Eco', allowing you to customize the drive level for your headphones or extend battery life.
Enhance your audio further with iFi's proprietary iEMatch technology, which adjusts the output level, and the XBass+ and 3D+ signature sonic enhancements, which add depth and dimension to your music.
Connectivity is a breeze with the micro iDSD Signature, featuring two digital audio inputs - USB Type-A and an S/PDIF socket that accepts both electrical and optical signals (adapter included). It also offers RCA analogue outputs for integration with powered speakers or amplifiers, and two headphone outputs - a 6.3mm jack for standard single-ended connectors and a 4.4mm Pentaconn output for balanced connections. Both outputs employ iFi's 'S-Balanced' circuitry, reducing crosstalk and distortion.
The Burr-Brown True Native chipset is a testament to the device's commitment to maintaining the integrity of your music, ensuring that file formats stay unchanged throughout playback. The DAC's four-channel True Native design allows PCM and DSD to take separate paths, preserving the 'bit-perfect' quality of the audio.
Experience Master Quality Authenticated (MQA) audio right out of the box, bringing the original master recording's fidelity into your personal listening space. The custom OV Series operational-amplifier contributes to the device's extremely low noise and distortion, while the Texas Instruments low-noise ICs, Panasonic OS-CON capacitors, and the DirectDrive circuit design all play pivotal roles in delivering an audio experience that is as authentic as it is immersive.
Elevate your audio journey with the micro iDSD Signature DAC and Headphone Amplifier, where precision engineering meets audiophile passion, resulting in an out-of-this-world listening experience.
