Topping - LA90 Discrete

TOPPING IS BACK WITH THEIR ALL-NEW HIGH-POWER DISCRETE POWER AMPLIFIER - THE LA90 DISCRETE

The Topping LA90 is a high-powered discrete power amplifier meticulously crafted with top-tier components, catering to premium speaker systems. Its distinctive feature is the NFCA discrete amplifier circuit, specially designed to meet the demands of high-end speaker setups. This amplifier effortlessly transitions between Stereo and Mono Modes, delivering substantial power in both configurations. The LA90 offers two-step gain settings, ensuring up to 120W per channel in stereo mode and 220W in mono mode. With the precision-engineered NFCA circuit, the Topping LA90 provides clean power, with minimal distortion and impressive SNR (Signal-to-Noise Ratio) performance. As a flagship product, the Topping LA90 is the perfect choice for elevating the audio quality of your speaker system.

EXPERIENCE TOP-QUALITY PERFORMANCE OF THE NEWLY DEVELOPED NFCA CIRCUIT WITH THE LA90 DISCRETE

The Topping LA90 Discrete incorporates a state-of-the-art discrete NFCA (Nested Feedback Composite Amplifier) power amplifier circuit, which relies on meticulously optimised individual components rather than integrated circuits, resulting in enhanced audio performance. This innovative design significantly reduces distortion, improves linearity, and offers precise control over the audio signal. Prepare to be amazed by the exceptional level of performance, immersing yourself in an audio experience characterised by a clean and deep background. This updated iteration of the LA90 model brings increased power in stereo mode, a heightened signal-to-noise ratio for clean amplification, and a broader dynamic range, further enhancing the quality of sound reproduction.

DELIVERS HIGH POWER OUTPUT WITH LOW DISTORTION AND OFFERS SELECTABLE STEREO AND MONO OUTPUT

The Topping LA90 Discrete sets new standards for performance with its high-quality discrete circuit. It boasts a low distortion level of under 0.0001% while delivering high power output. This means it maintains minimal distortion even under heavy loads, such as commonly used 4Ω and 8Ω loads, where it keeps distortion at around 0.0001%, ensuring pristine sound quality. These distortion levels are comparable to top-tier Amps, guaranteeing accurate reproduction of the original music source. The LA90 Discrete maintains low distortion across a wide operational range and under various load conditions. It offers both stereo and mono modes, allowing flexibility for different audio setups. In stereo mode, it delivers 120W x2 @4Ω and 66W x2 @8Ω, while in mono, the LA90 Discrete impressively provides 180W @4Ω and 220W @8Ω.

SELECTABLE GAIN SETTING FOR OPTIMAL AUDIO CONTROL WITH AN ARRAY OF INPUT AND OUTPUT PORTS

Topping has a rich history of creating exceptional and audiophile-friendly products, and the LA90 Discrete is no exception, offering both an appealing design and impressive sound quality. Its 2-step gain settings provide users with the ability to fine-tune their audio experience. In stereo mode, the gain settings include +9.4dB and +19.4dB, while mono mode offers +15.4dB and +25.4 dB options. You can utilise the LA90 Discrete's volume control or set it to bypass mode, allowing for the use of an external preamplifier for volume adjustments. The LA90 features three input ports that support both XLR and TRS connections, giving users the option to connect the LA90 to three different sets of input sources and switch between them seamlessly. Additionally, speaker outputs are available to connect to your speakers.

SEAMLESS INTEGRATION WITH 12V TRIGGER INTERFACES AND WITH THE TOPPING A90 DISCRETE DAC

The Topping LA90 Discrete is thoughtfully designed with a 12V trigger input and output trigger interface, making it easy to integrate with other devices. This feature allows users to conveniently power multiple audio devices on and off simultaneously, eliminating the need to manage them individually. If you require a headphone amplifier, it's recommended to consider pairing the LA90 Discrete with the A90 Discrete. This combination not only provides a headphone amplifier but also functions as a pre-amplifier for the LA90 Discrete. It's worth mentioning that the A90 Discrete offers additional features such as a remote control and input expansion for enhanced convenience.

EXPERTLY BUILT WITH AN ALL-ALUMINIUM ENCLOSURE WITH PASSIVE COOLING FOR OPTIMUM PERFORMANCE

The Topping LA90 Discrete is crafted with precision from top-grade CNC-machined aluminium, resulting in an enclosure that not only boasts a refined appearance but also offers robust protection. This elegant design is not merely aesthetic; it serves the crucial purpose of safeguarding the LA90 Discrete while facilitating passive cooling on both sides. This dual-sided cooling design plays a pivotal role in maintaining the amplifier's reliability during extended usage. By efficiently dissipating heat, it ensures that the LA90 Discrete's amplifier circuitry functions optimally, even during prolonged listening sessions. This meticulous attention to both form and function reflects Topping's commitment to delivering a premium audio experience.
