يتربّع iDSD Diablo ، بتصميمه الجديد الأنيق ولونه الأحمر الناري، بفخر على قمة مجموعتنا من المحولات الرقمية التناظرية ومضخمات صوت سماعات الرأس DAC / Amps المحمولة. تم تصميمه للمتخصصين - عشاق سماعات الرأس الحقيقيين الذين يتوقون إلى أداء صوتي نقي وصافي. تمامًا مثل سيارة السباق المصممة لسرعة لا هوادة فيها ، يخصص iDSD Diablo الإداء الصوتي بالإضافة إلى اتصال Bluetooth للتركيز على الطاقة الصوتية الخالصة. استعد لرحلة مثيرة لأن iDSD Diablo سيقود أي سماعة رأس على هذا الكوكب بثقة.
الميزات:
Balanced, differential analogue circuit design reduces noise and cross-talk within the signal path by fully separating the left and right channels. The iDSD Diablo benefits from further refinements to our balanced, symmetrical dual-mono topologies with short, direct signal paths. We call this PureWave.
Negative feedback is used in amplifier circuits to compare the output signal with the input signal and correct errors. BUT there are drawbacks. iFi turns the negatives into positives with OptimaLoop.

The iDSD Diablo’s focus on pure, unadulterated performance, means much attention has been applied to the power supply circuity.
Battery power provides ultra-clean and stable DC current avoiding the issues of mains electricity – dips, spikes and noise-inducing RFI/EMI pollution. BUT there are sonic downsides resulting from low output voltage and inconsistent output impedance as batteries discharge.
These issues are fully tackled by the iDSD Diablo’s design.
In order to make less efficient headphones, like planar magnetics, sing, the voltage needs to be stepped up from 3.7V to +/- 15V. We use a step-up converter running at 1.2MHz – a frequency far beyond audibility that is easier to filter than a typical switch-mode supply, enabling high linearity and ultra-low noise.
At the front of the unit, alongside a standard 6.3mm single-ended headphone socket, resides a 4.4mm Pentaconn output for headphones offering balanced connection.
At the back are two digital audio inputs: USB-A and a S/PDIF socket that accepts both electrical and optical signals, the former via a 3.5mm connector and the latter via a supplied adapter.
The USB-A input features a ‘male’ connector, rather than a typical ‘female’ port for greater mechanical integrity. A separate USB-C charging port is also provided, along with a 4.4mm Pentaconn balanced output to connect to an external amp.
