The Come Back of Linear Amplifier

New LA90 is making a new breakthrough, reaching a new level of pristineness and accuracy. The unprecedented level of performance will bring you absolute amazement at the sound quality. The sound doesn't get any clearer than this.

High-precision CNC-machined All-aluminum Housing

TOPPING LA90 adopts a high-precision CNC-machined all-aluminum housing, providing the product with exquisite details and solid protection. The built-in giant heat sink offers reliable and fast heat dissipation for the LA90'samplifier circuit.

Low Distortion While Outputting High Power

The LA90 features 0.00007%@8Q10W and 0.00008%@4Q20W typical THD+N, which is already as low as an excellent DAC. It is a more accurate reproduction of the music source. The LA90 has a wide working range with low distortion under load. Even in the commonly used 4Ω load 1W-60w output and 8Ω load 1W-40W output, the LA90 can control the distortion by around 0.0001%.

Selectable Working Modes & Mono

The TOPPING LA90 can be configured in a regular stereo two-channel mode, or in a high-power mono mode. When using mono, the minimum load is 8Ω. You can control the volume, or set to bypass the volume control of LA90, and then you can use a better pre-amplifier for volume control. It is useful when synchronizing the volume of two LA90 in mono mode.

Designed for Various Purposes

As a pure power amplifier, Pre90 and LA90 can associate with the D90SE DAC, which is almost the lowest distortion DAC + amplifier combination. When used as a pure power amplifier, Pre90 is the best. The Pre90 brings better volume control, remote control, more inputs, and a high-power combination of 1x Pre90 + 2x LA90 can easily be achieved.
