Know before you buy
No, the iDSD Diablo is strictly a wired device. It was designed to bypass wireless transmission entirely to ensure the highest possible signal purity and audio fidelity.
Yes, it is exceptionally powerful. With up to 5000mW of output and three selectable gain modes, it is capable of driving even the most demanding planar magnetic or high-impedance headphones with ease.
The gain settings allow you to match the amplifier's power output to your specific headphones. Use 'Eco' for sensitive in-ear monitors to prevent background hiss, 'Normal' for standard headphones, and 'Turbo' for demanding over-ear models.
Yes, it features full MQA decoding. This means it performs the complete 'unfolding' of MQA files internally, ensuring you hear the audio exactly as the artist intended in the studio.
Battery power provides a clean, stable DC current that is free from the electrical noise and interference often found in AC wall power. This results in a lower noise floor and a more transparent, detailed sound signature.
The device is highly versatile, offering a 3.5mm single-ended jack, a 6.35mm jack, and a 4.4mm balanced output. It also includes an XLR balanced output, making it compatible with almost any headphone cable termination.
