The Diablo 2, dressed in Devil Red, succeeds the Diablo-X with a series of improvements, such as increased headphone output power, support for lossless Bluetooth codecs, xMEMS technology, iEMatch, USB-C input, enhanced circuits, and more.

This headphone amplifier offers the best performance for both home and portable systems. It features a powerful maximum output of 5,180mW and symmetrical dual mono audio circuits, making it the most powerful headphone amplifier in its category.

The Diablo 2 is the world's first portable DAC/Amp with Bluetooth 5.4, supporting the aptX Lossless codec, allowing for CD-quality wireless audio streaming without loss.

The previous version introduced support for xMEMS technology, enhancing the performance of IEMs and headphones with significant advantages:

• Mechanical response of 15µsec, 150 times faster than standard drivers.
• Stable phase response of 2°, for accurate sound and simultaneous phase of +/- 1° for improved spatial sound accuracy.
• Silicone diaphragm speaker, 95 times more rigid than plastic, reducing speaker breakup and providing clearer mid-high frequencies.

The Diablo 2 offers three power modes: Normal for IEMs, Turbo for medium-sensitivity headphones, and Nitro for demanding headphones, with a maximum output of 19.2V. The iEMatch mode is specifically designed for high-sensitivity headphones, reducing noise and extending the usable volume range.

It comes with one 6.3mm headphone jack and one balanced 4.4mm jack, as well as a 3.5mm to 6.35mm adapter for flexible connectivity.

The Diablo 2 supports all modern Bluetooth formats and provides Bit-Perfect support for DSD and PCM with samples up to 768kHz and DSD512, as well as full MQA decoding.

It comes with four wings for horizontal or vertical placement, enhancing cooling with twenty-two rails that are compatible with the Diablo wings.

On the front panel, there is a volume lock switch next to the volume control, preventing accidental adjustments during transport. There is also a mode selection switch and a Bluetooth pairing switch.
