FOSI AUDIO ZD3 DAC

Fosi Audio's ZD3 is a balanced DAC with excellent connectivity thanks to its multiple inputs and Bluetooth 5.0 chip. The digital/analogue conversion is based on an ES9039Q2M chip, which supports PCM up to 32bit 768kHz and DSD up to DSD512. Three DIP8-mounted OPAs can also be replaced if you wish to have a different tone.

Fosi Audio ZD3: Balanced architecture

In order to deliver the cleanest possible sound, Fosi Audio opted for a symmetrical architecture during the design of the ZD3, drastically reducing the distortion that one channel could create on the other.

Fosi Audio ZD3: Interchangeable OPA

The ZD3's amplification stage is based on LME49720 OPAs with an output level of 5Vrms on XLR and 2.5Vrms on RCA. However, as these are DIP8 mounted, you can easily replace them with other OPAs with a different sound profile to adapt the pre-amplification to your tastes.

Fosi Audio ZD3: Low noise low-dropout regulator

To ensure the cleanest possible power supply, the ZD3 features a number of very low-noise voltage regulators, ensuring that the power needed to operate the device does not pollute your audio signal.
