Test By Audio Science Review

It is my pleasure to strongly recommend the Topping Pre90. If you needed to have another source beside your DAC to play in your system, you now have a wonderful way to accomplish that with zero impact on performance.

Balanced & Single-Ended

Versatile, the SP400 has both balanced and unbalanced inputs and outputs. The SP400 is equipped with both balanced and unbalanced inputs and outputs, so both unbalanced RCA and balanced XLR inputs are available. On the output side, the SP400 offers an unbalanced 6.35mm jack headphone output, a balanced XLR 4-pin headphone output and a balanced XLR Pre-Out output.

Design

All of the SP400's components are integrated into a beautiful CNC machined aluminum housing. The design of the SP400 follows the design of the other devices in the range for visually consistent integration.

The front of the device is also adorned with a beautiful OLED screen, displaying all the useful information and allowing intuitive navigation.

Adjustable gain

In order to adapt to all types of helmets, the SP400 offers a 3-level gain control. Thus, it is possible to use either a high-sensitivity helmet or a high impedance model.
