[🎶SG] Topping LA90 AB Class Power Amplifier

Breaking New Ground
Ultra-High Performance Power Amplifier

--
Descriptions:

>The come back of linear amplifier
The new LA90 is breaking new ground. It reaches a new level of pristineness and accuracy. The unprecedented level of performance will bring you the absolute amaze on the sound quality. The background doesn't get any darker than this. The sound doesn't get any cleaere than this.

>Rock solid
The 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 provides realiable and fast heat dissipation for the LA90's amplifier circuit.

>Low distortion while outputting high power
The typical THD+N of LA90 is 0.00007%@8Ω10w, 0.00008%4Ω20w. This is already as low as an excellent DAC. It means a more accurate reproduction of the music source. The LA90 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 can control the distortion around 0.0001%.

>Three sets of balanced inputs, compatible with XLR and TRS interfaces.

> 2 Step Gain settings.
Low Gain = +6.7dB
High Gain = +19dB

>Mono mode and Stereo mode
The LA90 can be configured in a common stereo two-channel mode, or can be configured in a high-power mono mode. When using mono mode, the minimum load is 8Ω.

You can control the volume on LA90, or set to bypass the volume control of LA90, then you can use a better pre-amplifier for volume control. This is especially useful when synchronizing the volume of two LA90 in mono mode.

When used as pure power amplifier, the LA90 can be used with D90SE DAC, which is almost the lowest distortion DAC + amplifier combination.

When used as pure power amplifier, the Pre90 pre-amplifier is recommended. The Pre90 brings a better volume control, remote control, more inputs, and a high-power combination of 1x Pre90 + 2x LA90 can easily be achieved.

When a headphone amplifier is required at the same time, it is recommended to use LA90 with A90 or A90 Discrete. They not only provide the heaphone amplifier, but also can be used as a pre-amplifier for the LA90. It is worth mentioning the the A90 Discrete also supports remote control and input expansion.
