Descriptions:

> Bring the magic of NFCA circuitry to your speakers
> Introducing the LA90 Discrete Amplifier, a high-fidelity audio solution that brings the benefits of discrete NFCA power amplifier circuitry to your listening sessions. This is a brand-new iteration of the LA90 model that features greater power in stereo mode, advanced signal-to-noise ratio for cleaner amplification, and wider dynamic range for even greater sonic reproduction.

> Explore the wonders of discrete NFCA circuitry
> The LA90 Discrete features a cutting-edge discrete NFCA (Nested Feedback Composite Amplifier) power amplifier circuit, which comprises individual components optimized for audio performance, rather than relying on integrated circuits. This design delivers superior sound quality by reducing distortion, improving linearity, and providing greater control over the audio signal.

> Versatile operation with stereo and mono modes
> The LA90 Discrete offers both stereo and mono modes, providing flexibility for a variety of audio setups. In stereo mode, it delivers 120W x2 @4Ω and 66W x2 @8Ω. In mono mode, the LA90 Discrete provides an impressive 180W @4Ω and 220W @8Ω.

> Gain settings for optimal audio control
> With 2-step gain settings, the LA90 Discrete allows users to fine-tune their audio experience. In stereo mode, gain settings include +9.4dB and +19.4dB, while mono mode offers +15.4dB and +25.4dB.

> Robust all-aluminum enclosure with passive cooling
> The high-precision CNC machined all-aluminum enclosure not only looks sleek but also provides reliable heat dissipation through passive cooling on both sides. This ensures the LA90 Discrete remains cool and performs optimally even when the evening gets away from you.

> Seamless integration with 12V trigger interface
> The LA90 Discrete comes equipped with a 12V trigger input and output trigger interface, allowing for easy integration with other devices. This feature enables users to switch multiple devices on and off simultaneously without the hassle of doing so individually.

> What's the difference: LA90 Discrete NFCA Power Amplifier vs LA90 Power Amplifier
> The LA90 Discrete NFCA version features the cutting-edge discrete NFCA (Nested Feedback Composite Amplifier) power amplifier circuit. This design uses individual components optimized for audio performance, delivering superior sound quality by reducing distortion, enhancing linearity, and providing greater control over the audio signal. The LA90 Power Amplifier version is now discontinued.
