Thanks to the use of a Qualcomm Bluetooth 5.4 QCC518x chip, the Diablo 2 is able to support the new aptX Lossless codec, which offers a maximum data rate of 1200kbps. In comparison, aptX Adaptive offers a maximum bit rate of 420kbps, while LDAC offers a bit rate of 990kbps.

iFi Audio iDSD Diablo 2: A host of proprietary technologies

The Diablo 2 features PureWave, Servoless DirectDrive, OptimaLoop and Advanced Jitter Reduction technologies, delivering exceptionally pure, detailed sound.

PureWave's fully symmetrical dual-mono circuit improves clarity by separating channels and reducing noise. DirectDrive eliminates the need for coupling capacitors, ensuring a cleaner sound. OptimaLoop uses multiple custom feedback circuits in the amplifier stage, refining gain control and reducing distortion. Finally, the femto GMT clock using Smart cache memory minimizes phase noise.

iFi Audio iDSD Diablo 2: Silent power supply

The Diablo 2 can be powered by battery or mains. Battery power provides clean, stable DC power, avoiding the problems associated with mains power, such as dips, spikes and noise-generating RFI/EMI pollution. However, to ensure that mains power can still be used satisfactorily, the Diablo 2 is equipped with the iPower2 power supply featuring Active Noise Cancellation II technology, which effectively cancels all incoming EMI and RFI noise, making it over 10 times quieter than most audiophile power supplies.
