Amplifier/Dac Bluetooth ifi neo idsd 2

The first DAC/AMP Bluetooth without losses in the world

It supports the new APTX Lossless, the only Bluetooth codec capable of transmitting audio with CD quality without losses, and has a powerful 5551 MW output that eclipses many headphones amplifiers.



It is Head-Fi. It is a desktop. And it is high fidelity.

The neo IDSD 2 is our new and versatile DAC/AMP 3 in 1, specifically designed for CAS audiophiles. It is combined effortlessly with its headphones such as a DAC/AMP Head-Fi, it can be used as a pure DAC with its integrated amplifier or serve as Dac/Preamplifier for its active speakers and power amplifier.

It has the last Bluetooth 5.4, compatible with the new APTX Lossless, the only Bluetooth codec capable of transmitting audio with CD quality without loss without sacrificing audio quality.

The NEO IDSD 2 has improved line outputs and headphones, which provides wide power for its most demanding headphones, as well as for power amplifiers.


My blue is not your blue. It is new and without losses.

The NEO IDSD 2 has the latest Bluetooth 5.4 technology, compatible with the new Aptx Lossless codec, which provides a maximum bit rate of 1200 kbps. In comparison, Aptx Adaptive has a maximum 420 kbps bits rate, while LDAC offers a higher bits rate than 990 Kbps.

However, Aptx Lossless is the first and only Bluetooth codec capable of transmitting Audio with CD quality without using a compression method that degrades sound quality. While other Bluetooth codecs claim to admit CD quality and even high -resolution audio, they use compression with loss during transmission, which negatively affects sound quality.

The NEO IDSD 2 used the new Bluetooth audio chip QCC518x of Qualcomm, is qualified for Bluetooth 5.4 and admits all* the Bluetooth formats, including: Aptx Lossless, Aptx Adaptive, APTX, LDAC, LHDC/HWA, AAC and SBC.

*As of September 22, 2023. Verify that your device is compatible with the Bluetooth codec.


5 times more headphones output power than your predecessor.

You listened to me correctly: the output power of the Neo IDSD 2 headphones is 5 times more powerful than that of the first generation neo IDSD. With a maximum headphone output power of 5551 MW (@ 32Ω), it even exceeds some dedicated headphones amplifiers, making them sweat. The headphones section has experienced a significant improvement, since we have essentially integrated a devil headphone circuit in it.

It has Auto Iiematch to reduce the annoying whistle of high sensitivity headphones without losing dynamic range and four gain configurations ranging from -12 dB to +16 dB, which makes it appropriate for all its IEM and types of headphones, from Super sensitive to those who consume a lot of energy.

The neo IDSD 2 is not only powerful, but is also designed for your ears. The recently added analog processing modes, Xspace and XBBASS II, along with the four digital filters, allow you to refine the sound. Both Xspace and XBBASS II are purely analog signal processing modes designed to adjust the sound scenario and the low frequency response to match its headphones.



Stop next to you. It doesn't matter above or down.

Whether you are using the neo IDSD 2 such as Desk-Fi or Hi-Fi, you can place it horizontally or vertically. The new 2 -inch color screen automatically rotates to adapt to orientation.

When you use it as desk-fi, you can place it vertically on your desk to save space. Configure it in variable output and with its powerful maximum balanced output of 19.5 V, it will work well with its active speakers with volume control. Volume control is analog, which is superior to any digital volume control.

When you use the NEO IDSD 2 as Hi-Fi equipment, you can place it in a horizontal position. It can serve as a pure DAC, reproducing all high -resolution music files from 32 -bit PCM/768 kHz to DSD512 and complete MQA decoding. You can also connect it directly to your power amplifier as a preamplifier, using its analog volume control.



GMT femtoprecision clock. Update.

The internal GMT femtoprecision clock, combined with an intelligent storage cache memory, forms an advanced fluctuations reduction system. Effectively reduces fluctuation of the digital signal, producing a cleaner and more precise sound.

If you have a more precise external clock, or if you want to synchronize with other devices such as CD players or network transmitters that have an external clock input, you can connect both the neo IDSD 2 and the other devices to the external clock through the entrance of 10 MHz external synchronization clock for even larger clock signal accuracy.

It is rare to find an external synchronization clock input in this price range. Even if it does not have an external clock, the internal GMT femtoprecision clock offers excellent performance in its class.


More than new functions. Improved circuits.

The improved design of the Purewave Circuit of the Neo IDSD 2, with its balanced dual monkey topology and short signal routes, is known for its excellent linearity and its minimum noise and distortion, offering exceptional sound purity.

The results are a improved signal -fed -signal relationship (SNR) of> 120 dB (A), a dynamic range (DNR) of -120 dB (a) and a total harmonic distortion plus noise (thd+n) of <0.0015 %, which brings the performance of the neo IDSD 2 is along with the DAC of a higher price.
