The module features high voltage swing and low output impedance for powerful yet clean sound reproduction.
About iBasso AMP8 MK2
The iBasso AMP8 MK2 brings dedicated amplification power to the DX240 digital audio player. This discrete module adds both balanced and single ended headphone outputs so users gain flexibility in cable choices while enjoying stronger drive capability. The design supports demanding headphones through its high voltage swing and current delivery which translates into improved dynamics and better overall control during listening sessions.
On the 4.4mm balanced output the module reaches a maximum level of 6.2Vrms and delivers 980mW at 32ohm along with 128mW at 300ohm. Signal to noise ratio hits 125dB and dynamic range matches at 125dB with very low distortion and crosstalk values. These numbers help the music come through with excellent clarity and separation so every detail stays preserved even at higher volumes.
The 3.5mm single ended output complements the balanced side by offering 3.1Vrms maximum level together with 281mW at 32ohm and 32mW at 300ohm. It maintains 122dB for both signal to noise and dynamic range while keeping output impedance low at 0.32ohm. Listeners benefit from consistent performance across different headphones without worrying about compatibility issues.
Premium components such as ERO film capacitors contribute to the clean sound signature of the AMP8 MK2. The high 8 volt operating voltage improves open loop linearity and the transistor buffer stage supplies up to 2000mA of current. This combination creates more headroom and accurate reproduction that feels engaging across various music genres.
Frequency response stays flat from 10Hz to 45kHz within tight tolerance on both outputs. Low output impedance values of 0.55ohm on balanced and 0.32ohm on single ended ensure tight bass control and minimal interaction with varying headphone loads. Users experience reliable power delivery that brings out the best in their audio collection.

Reviews
Finally found the extra drive my headphones needed. The balanced output pushes them with real authority and the soundstage opens up nicely. Every track feels more alive now.
Swapped in this module and noticed cleaner background noise right away. Bass tightens up while vocals stay smooth. It handles my collection without strain during long sessions.
Love how this adds both output types in one compact card. Dynamics improved a lot and details pop without fatigue. Makes my daily listening way more enjoyable overall.
