In addition to the headphone amplifier section, the A90 Discrete also includes a preamplifier. In the preamplifier, you get the same performance as in headphone amplifier mode. Single-ended 20Ω and balanced 40Ω outputs allow for the use of a wide range of amplifiers. What's more, both modes can be used simultaneously, and the remote control provides easy access to every function.
The A90 Discrete can be combined with the Topping EXT90, the latter offering the option of expanding the device's connectivity. With the EXT90 connected, you will have a total of four XLR inputs and two RCA inputs.
