The counterattack of discrete amplifier: LA90 Discrete, an unprecedented performance benchmark will bring you a breathtaking listening experience. The newly developed discrete NFCA power amplifier reaches a new level of pristine sound and accuracy. The unprecedented level of performance will bring you the absolute amaze on the sound quality. You will experience the darkest background you ever experienced with jaw dropping clarity.
Rock solid : The LA90 Discrete’s housing is a high-precision CNC machined all-aluminum enclosure that provides exquisite detail and rugged protection. Passive cooling on both sides provides reliable and fast heat dissipation for the LA90 Discrete’s amplifier circuitry.
Low distortion while outputting high power: The LA90 Discrete’s THD+N is <0.0001%@4Ω/5W, <0.0001%@8Ω/5W. This is already as low as an excellent DAC. It means a more accurate reproduction of the music source. The LA90 Discrete has a very 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 Discrete can control the distortion around 0.0001%.
BTL mode，More power than you need： High current discrete output circuit gives higher bridging power. With 4 ohms bridged, up to 180W of power is enough to make the sound more complete and fuller.
Mono mode and Stereo mode： The LA90 Discrete can be configured in the common stereo two-channel mode or in high-power mono mode, with a minimum load of 40 when using the mono mode.
