  • iFi Audio iDSD 2

    The NEO iDSD 2 is iFi Audio's versatile new 3-in-1 DAC/Amp, designed specifically for CAS audiophiles. It pairs effortlessly with your headphones as a Head-Fi DAC/Amp, can be used as a pure DAC with your integrated amplifier, or serve as a DAC/Preamp for your active speakers and power amplifier.

    NEO iDSD 2 is the world's first lossless Bluetooth DAC/Amp. Supports new aptX Lossless - the only Bluetooth codec capable of streaming lossless CD-quality audio, and boasts a powerful 5551mW output that outshines many headphone amps.

    It features the latest Bluetooth 5.4, supporting the new aptX Lossless, the only Bluetooth codec capable of streaming lossless CD-quality audio without sacrificing audio quality. The NEO iDSD 2 has improved headphone and line outputs, providing ample power for your high-demanding headphones, as well as power amplifiers.

    It’s head-fi. It’s desk-fi. And it’s hi-fi.

    My Blue isn’t your blue. It’s new and Lossless.

    The NEO iDSD 2 features the latest Bluetooth 5.4 technology, supporting the new aptX Lossless codec, which provides a maximum bitrate of 1,200kbps. aptX Lossless is the first and only Bluetooth codec capable of streaming CD-quality audio without using a compression method that degrades sound quality.

    Future-proof Bluetooth 5.4

    The NEO iDSD 2 used Qualcomm’s new QCC518x Bluetooth audio chip, is qualified to Bluetooth 5.4, supported all (As of 22 Sep 2023) Bluetooth formats including: aptX Lossless, aptX Adaptive, aptX, LDAC, LHDC/HWA, AAC and SBC.

    5x more headphone output power

    You heard me correctly – the headphone output power of the NEO iDSD 2 is a whopping 5 times more powerful than that of the 1st-gen NEO iDSD. With a maximum headphone output power of 5,551 mW (@ 32Ω), it outperforms even some dedicated headphone amplifiers, making them sweat. The headphone section has seen significant improvement, as we’ve essentially integrated a Diablo headphone circuit into it.

    Stand by you. No matter up or down.

    Whether you’re using the NEO iDSD 2 as a Desk-Fi or Hi-Fi, you can position it horizontally or vertically. The new 2-inch colour display automatically rotates to suit the orientation. When using it as a Desk-Fi, you can position it vertically on your desk to save space. Set it to variable output, and with its powerful 19.5V maximum balanced output, it works well with your active speakers with volume control. The volume control is analogue, which is superior to any digital volume control.

    GMT Femto-Precision Clock. Upgradable.

    The internal GMT femto-precision clock, combined with a smart storage cache, forms an advanced jitter reduction system. It effectively reduces jitter in the digital signal, producing cleaner and more accurate sound. If you possess a more accurate external clock, or if you wish to synchronize with other devices such as CD players or network streamers that have an external clock input, you can connect both the NEO iDSD 2 and the other devices to the external clock via the 10MHz External Sync Clock input for even greater clock signal accuracy.

    More than new features. Enhanced circuitry.

    The NEO iDSD 2’s enhanced PureWave circuit design, with its balanced dual-mono topology and short signal paths, is known for outstanding linearity and minimal noise and distortion, offering you exceptional sonic purity. The results are an improved Signal-to-Noise Ratio (SNR) of >120dB(A), Dynamic Range (DNR) of -120dB(A), and Total Harmonic Distortion plus Noise (THD+N) of less than 0.0015%, bringing the NEO iDSD 2’s performance on par with DACs at a higher price point.

    Hi-Res Audio

    Hi-res audio support is state-of-the-art with True Native® playback. It handles PCM data to 32-bit/768kHz, DSD up to DSD512 and single and double speed DXD. Thanks to the Burr-Brown DAC chip’s four-channel True Native design, PCM and DSD take separate pathways – this enables DSD, as well as PCM, to remain ‘bit-perfect’ in its native form right through to analogue conversion. This is not the case with all DAC devices from other brands – even if DSD compatibility is stated, many such DACs convert DSD signals to PCM.
