Topping LA90 Rock Solid Power Amplifier
For the past few days Topping has been teasing a brand new upcoming product through their social media profiles. Today, Topping has finally removed the drapes of this new product, meet the all-new Topping LA90.
With groundbreaking amounts of power, the LA90 is a brand new power amplifier from Topping designed to use with your HiFi speaker systems. Topping has designed the LA90 with a high-precision CNC machined all-aluminum housing giving an exquisite finish to the LA90. It has a giant heatsink built into the chassis ensuring fast heat dissipation for the circuitry inside. LA90 is a super powerful device that drives enough juice to power even the demanding speaker setups. It also supports mono mode outputting powerful driving force with ultra-low distortion. Topping LA90 Power amplifier is designed keeping in mind the premium range of desktop gears from Topping such as their current flagships D90, A90, and Pre90.

Your Rock-Solid Power Amplifier
Topping LA90 has a robust build with a CNC machined aluminum frame. The amplifier has an in-built giant heat sink on both sides that provides fast and reliable heat dissipation for the amplifier circuit. With its powerful amplification and dedicated heat sink, the LA90 provides you with a smooth and clean performance.
Ultra-Low Distortion & Clean Background
Topping has designed the amplifier circuit of the LA90 to achieve ultra-low distortion and high SNR ratings while driving powerful loads. The amplifier achieves as low as 0.00009% THD+N ratings @ 4Ω of load. The LA90 maintains this low distortion, when in Mono mode this even gets lowered to as low as 0.00001%.
Supports Both Stereo & Mono Modes
The Topping LA90 can be used as a stereo two-channel amplifier or as a high-power mono amplifier. In the Mono mode, it is recommended to use 8Ω and above impedance loads. The stereo mode supports 4Ω and above impedance loads. In the mono mode, the THD+N Distortion value is further lowered and achieves an even cleaner performance.
Three Sets Of Selectable Inputs
Compatible with both the XLR and the TRS interfaces, the Topping LA90 has three different input ports. These inputs can be switched easily as required. Connect your power amp to three different sources at once and switch as you require.
Ultra-Solid Amplification With Two-Level Gain
Topping LA90 houses boat loads of power. In stereo mode, it outputs up to 110W@4Ω of load and in Mono mode, it provides up to 220W@ 8Ω of load. These numbers are extremely good, these reflect the LA90 can power most speaker setups in the industry. It has two level gain settings with +6.7dB gain in Low-Gain mode and +19dB in the high gain mode.
Bypass The Volume With Pre-AMP
You can connect a pre-amp to the LA90 and bypass the volume control of the LA90. This is especially useful when you are synchronizing the volume of two LA90 power amplifiers in mono mode via a dedicated pre-amplifier. If you want to have a headphone amplifier too in the chain, you can connect it with A90, where A90 will act as a pre-amplifier for the LA90.
Price & Availability
Topping LA90 is priced officially for 899$. You can check out more details here.
