Know before you buy
The LA90 is a versatile Class AB amplifier that performs well with a wide range of bookshelf and floor-standing speakers. With its 90W output at 4 ohms, it provides sufficient power for most standard home Hi-Fi setups, though you should verify your speakers' sensitivity and impedance requirements to ensure a good match.
Yes, the LA90 features both XLR and RCA inputs, allowing you to connect multiple audio sources. You can easily switch between these inputs depending on your current setup needs.
The Class AB design is chosen for its balance of efficiency and high-fidelity performance. It minimizes crossover distortion, which helps the LA90 deliver a cleaner, more precise sound compared to many standard amplifiers in its class.
Yes, the LA90 is a dedicated power amplifier, meaning it requires a pre-amplifier or a DAC with volume control to manage your input signals and volume levels before they reach the speakers.
The discrete NFCA (Nested Feedback Composite Amplifier) circuitry is designed to maintain signal purity and reduce noise. This results in an exceptionally high signal-to-noise ratio and ultra-low distortion, ensuring that your music remains clear and detailed even at higher volumes.
The LA90 is engineered to handle loads down to 2 ohms, where it can output up to 150W per channel. This makes it a robust choice for speakers that dip into lower impedance ranges, providing the necessary headroom for dynamic audio.
