I got some more details about the stepped attenuator. Because this pot is so very small, the contacts and the shaft need to be long term reliable and of great quality. Therefore, the shaft and the contact points need some tolerances. Hence one may need to play around to dial in their volume
According to iBasso, when adjusting the volume, 5%-10% of the time, there will be no sound in both channels and you need to gently turn the volume knob clockwise slightly more to restore the sound.

This could become annoying if I adjust the volume frequently. So would the sound improvement be worth the inconvenience?

No more Tantrums!

Some specs:

- The digital and analog sections of the DX320MAX are powered separately, with each having an independent charging system. The digital and analog hardware and signal communications, adopt optocouplers and I2C isolators to completely isolate the digital to analog sections from any interference.
- The AMP section is powered by a true +/- 8.4V battery pack. No voltage boost is used, which ensures the highest purity and current output.
- An optimized super class A discrete amp circuit, which eliminates the switching distortion
of transistors, while providing the sound signature of a class A amplifier, that also significantly reduces heat generation, is used.
- The DX320MAX has versatile outputs that incorporate a 4.4mm balanced phone out/ line out, and a 3.5mm single ended phone out/ line out.
- The voltage output of the 3.5mm single ended is up to 4.5V RMS, and the balanced phone output is up to 9V RMS.
- Electrolytic capacitors and film capacitors are used in the DX320MAX.
- A custom analog 4-wiper stepped attenuator that has less than +/-0.1dB channel tolerance imbalance, has been selected.
- 4 settings for the physical gain control.
- 5.0" IPS screen (1080*1920), with On Cell capacitive touch panel.
- Quad BD34301EKV ROHM DAC Chips are incorporated.
- Bit for Bit playback with support up to 32bit/768kHz.


Changing the batteries is easy. Two screws are used to hold on the back.

Impressive, most impressive.

Right!!! Seems to be amazing as adopting 4X ROHM as the flagship of Ibasso implementation.

The Cayin N8ii sports 2X of them and heat up like a griller. Now we have 4X ROHM with easily battery swap that means a lot longer life time to keep!!

The amplification adopt from previous generations with more improvements to suit the flagship implementation of the DAC ? Though more details in that would be nice !!!

Ibasso once again is showing their innovations in engineering and developments !! Who else is out there enabling all DAC channels from desktop DAC like Ibasso in Ultimate mode ?
