Topping LA90, Class AB Power Amplifier: High-Resolution Audio AMP (LA 90)

Linear Amplifier: LA90 reaches a new level of purity and accuracy. Unprecedented level of performance brings absolute wonder to sound quality. The background will never be darker.

Low distortion at high output: LA90's signature THD + N is 0.0007% @ 8Ω 10W, 0.0008% @ 4Ω 220W. This is already as low as the good DAC. This means more accurate playback of the music source. The LA90 has a very wide range of operation with less distortion at stress The LA90 can control the distortion of 0.001% around 0.001% from the common 4 Ω load 1 W to 40 W output

Control the volume with the LA90 or set it to bypass the volume control of the LA90, then you can use the preamp with excellent volume control. This is especially useful when synchronizing two LA90 volumes in mono mode

Pre90 preamp is recommended for use as a pure power amplifier. The Pre90 provides better volume control, remote control, and more input, and can easily achieve high output combination of 1x Pre90 +2xLA90
