aptX Lossless Bluetooth is Finally Here: iFi NEO iDSD 2

The Wait is Over. Lossless Bluetooth is Finally Here.

Why the Old Bluetooth Codec Falls Short for Hi-Fi.

Bluetooth is a wireless technology that enables data exchange between devices over short distances. It’s commonly used to connect headphones, speakers, and peripherals to smartphones and computers.

However, Bluetooth’s biggest limitation has been transmitting high-quality audio. Originally designed for phone headsets and speakerphones, Bluetooth’s narrow bandwidth necessitates audio data compression, which compromises music reproduction quality.

What is Lossless Bluetooth, also known as aptX Lossless?

Many current Bluetooth codecs claim to support CD-quality and even hi-res audio. Yet, they employ lossy compression during transmission, leading to audio quality degradation. For context, AAC’s bitrate peaks at 320kbps, aptX Adaptive at 420kbps, and LDAC at 990kbps. Considering that a CD audio file’s bitrate stands at 1,411kbps, these codecs inevitably introduce some loss.

In contrast, aptX Lossless operates at a maximum bitrate of 1,200kbps. While it does use compression, the method produces results akin to FLAC (Free Lossless Audio Codec), ensuring no sound quality degradation. This distinction makes it the only Bluetooth codec delivering true CD-quality (16-bit/44.1kHz) audio.

The World’s First Lossless Bluetooth DAC/Amp the NEO iDSD 2

Our NEO iDSD 2 is a versatile 3-in-1 DAC/Amp designed specifically for CAS audiophiles. It seamlessly pairs with headphones as a Head-Fi DAC/Amp, serves as a pure DAC with an integrated amplifier, or functions as a DAC/Preamp for active speakers and power amplifiers.

Boasting the latest Bluetooth 5.4 technology, it supports the new aptX Lossless, the sole Bluetooth codec offering lossless CD-quality audio without sound quality compromise.

What differentiates us? Beyond using the standard QCC518X SDK (software development kit), we’ve partnered with Qualcomm engineers to bring new functionality and modules exclusive to NEO iDSD 2. These innovations encompass LDAC, LHDC, Custom XMOS interface, Personalized Device Name, Real-time receive & transmit switching, Stereo (non-TWS) receiver, SPDIF Input, aptX Lossless indicator*, and I2S Input*.

*Features are still under development.
