THE COMEBACK OF THE ULTRA-HIGH PERFORMANCE CLASS AB LINEAR POWER AMPLIFIER
TOPPING is known to make the quietest and most linear power amplifiers. The design engineers keep the amplifiers precise so that they can deliver out of the box audio performance. The TOPPING LA90 comes as no surprise having near-perfect square wave performance, and the lowest noise of existing power amplifiers. The LA90 is a game-changer; it achieves a new degree of pristineness and precision. The unrivalled level of performance will leave you speechless with the sound quality delivered by LA90. The LA90 presents the most crystal-clear sound you'll ever hear. Topping engineers are bringing their expertise in designing ultra-low noise and distortion in headphone amplification to power amplifiers.
DELIVERS EXCEPTIONAL PERFORMANCE WITH LOW DISTORTION WHILE OUTPUTTING HIGH POWER IN STEREO AND MONO MODE
TOPPING introduces the LA90, a power amplifier with a class AB configuration that allows it to deliver high power without distortion. The TOPPING LA90 can be configured in stereo two-channel mode or high-power mono mode. In stereo mode, it is capable of delivering a power of 90Wx2 @4Ω (1% THD+N), 110Wx2@4Ω (10%THD+N), 65Wx2 @8Ω THD+N<10%, 50Wx2 @8Ω THD+N<1%. In the high-power mono mode, it will be able to provide a power of 180Wx1 @8Ω (1% THD+N) and 220W @8Ω (10%THD+N). The (total harmonic distortion) THD+N of the LA90 is 0.00007% @8Ω10W and 0.00008% @4Ω 20W, similar to a high-end digital audio converter. It entails a more precise reproduction of the music source. The LA90 has a vast operating range and minimal distortion when loaded. It can regulate distortion within 0.00001% in the commonly used 4Ω load 1W-60W and 8Ω load 1W-40W outputs.
STRIKING LOOKS WITH KEY FEATURES THAT INCLUDE SELECTABLE GAIN AND A WIDE ARRAY OF INPUT-OUTPUT CAPABILITIES
TOPPING has a long history of producing visually stunning and audiophile-friendly products. The LA90 looks incredible with its simple yet elegant design. You can utilise the LA90's volume control or set it to bypass, allowing you to use an external preamplifier for volume control. The LA90 has two gain settings: low gain +6.7dB and high gain +19dB, allowing you to link power-hungry headphones that demand high gain. Moreover, the LA90 provides three sets of balanced inputs (XLR), TRS single-ended and pre-amp and post-amp options, which are compatible with XLR and TRS interfaces and suitable for stacking/pairing with D90SE, A90, and Pre90.
IMMACULATE PERFORMANCE ACHIEVED BY PAIRING LA90 WITH THE TOPPING PRE90 AND D90SE DAC
If you're looking to achieve distortion-free and clean sound, consider pairing LA90 with D90SE DAC. When utilised as a pure power amplifier, the Pre90 preamplifier is recommended. The Pre90's improved volume control, remote control, and additional inputs make it easy to achieve a high-power combination of 1*Pre90 +2X LA90. When a headphone amplifier is required, the LA90 with A90 or A90 discrete is the ideal setup. They can be used not just as a headphone amplifier, but also as a pre-amplifier for the LA90. It's also worth noting that the A90 discrete has a remote control and input expansion capabilities.
ELEGANT BUILD WITH HIGH-PRECISION CNC-MACHINED ALL-ALUMINIUM HOUSING PROVIDING A ROCK-SOLID FEEL
TOPPING has always strived to push the frontiers by developing products that combine stunning design and build quality. The LA90 adopts a high-precision CNC-machined all-aluminium 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's amplifier circuit. The shell of the LA90 is the height of the stack of Topping D90se and A90.
