About this deal

In mono mode, the LA90 outputs 98Vpp@8Ω, while the LA90D offers a slightly higher 106Vpp@8Ω. Furthermore, the maximum dynamic range of the LA90 is 142dB, while the LA90D boasts a slightly higher 143dB. These differences, although subtle, can contribute to the overall sound quality and listening experience. Conclusion: A Look at the Evolution of the LA90 Series Topping LA90 houses boat loads of power. In stereo mode, it outputs up to 110W@4Ω of load and in Mono mode, it provides up to 220W@ 8Ω of load. These numbers are extremely good, these reflect the LA90 can power most speaker setups in the industry. It has two level gain settings with +6.7dB gain in Low-Gain mode and +19dB in the high gain mode. Accidents, abuse, misuse, improper installation, problems with electrical power, acts of third parties.

The LA90D comes with a 12V trigger interface, allowing it to be easily integrated into a larger audio system. This feature was not available in the LA90. Size: No Difference Here LA90 Discrete can be set up as a combined machine and can control its own volume. L A90 Discrete can be configured into a power amp without volume control. This is convenient especially for dual mono use. Furthermore, it can be used with the D90SE DAC, which is almost the lowest distortion DAC + amplifier combination. Amir has measured the A90-D and its nearly the same performance as the original A90 so it should be great match for the LA90-D Customers are to bear the consequences and fees incurred, if the parcel was undelivered due to any of the following situation: Specs aside, (amp numbers way better than dac!), couldn't be happier. Completely dead quiet & no sonic signature that I can discern. Just saying, the little LS-50's music never sounded cleaner & smooth clear with many familiar jazz & classical "refs". I've run them previously with an Odyssey Khartago, Plinius Odeon, Kinki M-7 & Purifi ET-400 etc So I've got their 'sonic flavour' down, and thru the Topping it's as good as, with a cherry and chocolate sprinkles!

Mono & Stereo

In the world of audio amplifiers, TOPPING has been making waves with its high-quality products. Recently, TOPPING discontinued their LA90 power amplifier to make room for the second generation LA90 Discrete NFCA Power Amplifier (LA90D). Both models offer impressive performance, but there are some key differences you should know about. In this comparison, we'll explore their similarities, differences, and use cases to help you understand how the newest model outshines its predecessor. Discrete Amplifier Circuit: Introducing NFCA While both amplifiers have 2-step gain settings, there are some differences in the values. The LA90 offers gain settings of +6.7dB and +19dB, while the LA90D provides +9.4dB and +19.4dB in Stereo mode and +15.4dB and +25.4dB in Mono mode. This distinction may affect the sound output depending on the user's preferences and listening environment. Mono and Stereo Modes: Flexibility for Both

Any item returned incomplete or with physical damage such as scratches etc., excessive signs of use, or abuse will not be accepted for return. Both the LA90 and LA90D feature a CNC-machined all-aluminum housing with passive cooling on both sides, ensuring efficient heat dissipation. This design helps to keep the amplifiers cool and operating optimally, even during extended use. Balanced Inputs: A Draw LA90 Discrete comes with three sets of balanced inputs, compatible with XLR and TRS interfaces, allows 2-step Gain setting. It can be configured in the common stereo two channel mode or in high-power mono made, with a minimum load of 42 when using the mono mode. Both amplifiers share the same dimensions, making it easy to compare them in terms of physical appearance and integration into your existing setup. Voltage and Dynamic Range: A Small Edge for the LA90D The LA90 offers a respectable 110W x 2 in stereo mode, while the LA90D steps up the game with 120W x 2. This extra power can make a difference for those who want a little more oomph in their audio setup. SNR: Advantage LA90D

Damage due to user negligence, accidents, disassembly, waterlog, misuse, abuse, alterations or vandalism. Any item returned must be complete with all accessories, hardware, manuals, or instructions, and in the same "new" condition as when it was when shipped to you. Please send us photos or videos of it. This warranty extends only to personal use & does not extend to any product that has been used for commercial use, rental use, or use that is not intended. There are no warranties other than expressly set forth herein. Topping LA90 features three input ports that support both XLR and TRS inputs. Users can connect the LA90 to three different sets of inputs and can switch between them easily and swiftly. Selectable Stereo and Mono Outputs:-

The comparison between the TOPPING LA90 and LA90D provides a fascinating look at the evolution of these power amplifiers. While the LA90 is discontinued, it's interesting to see how TOPPING built upon its design to create the improved LA90D, which boasts an NFCA discrete amplifier circuit, a higher SNR, and more powerful output. When it comes to signal-to-noise ratio (SNR), the LA90D holds the advantage with an impressive 143dB, compared to the LA90's 140dB. A higher SNR means a cleaner, more detailed sound. Built for Heat Dissipation: Both Models Shine If you also require a headphone amplifier, it is recommended to use LA90 Discrete with A90 Discrete. They not only provide the headphone amplifier, but also can be used as a pre-amplifier for the LA90 Discrete. It is worth mentioning that, the A90 Discrete also supports remote control and input expansion. Both the LA90 and LA90D can operate in mono and stereo modes, giving users flexibility in configuring their audio setups. Trigger Interface: A Unique Feature for the LA90DIf it is plastic sealed when you get it, it should remain plastic sealed. Some types of goods such as CIEMs and custom cables cannot be returned. You can connect a pre-amp to the LA90 and bypass the volume control of the LA90. This is especially useful when you are synchronizing the volume of two LA90 power amplifiers in mono mode via a dedicated pre-amplifier. If you want to have a headphone amplifier too in the chain, you can connect it with A90, where A90 will act as a pre-amplifier for the LA90.

The Topping LA90 can be used as a stereo two-channel amplifier or as a high-power mono amplifier. In the Mono mode, it is recommended to use 8Ω and above impedance loads. The stereo mode supports 4Ω and above impedance loads. In the mono mode, the THD+N Distortion value is further lowered and achieves an even cleaner performance. Three Sets Of Selectable Inputs:-

High power & Low distortion

Compatible with both the XLR and the TRS interfaces, the Topping LA90 has three different input ports. These inputs can be switched easily as required. Connect your power amp to three different sources at once and switch as you require. Ultra-Solid Amplification With Two-Level Gain:- The THD+N is <0.0001%@4Ω/5W, <0.0001%@8 Ω/5W. This is already as low as an excellent DAC. It means a more accurate reproduction of the music source. The LA90 Discrete has a very wide working range with low distortion under load. Even in the commonly used 4 Ω load 1W-60W output and 8 Ω load 1W-40W output, the LA90 Discrete can control the distortion around 0.0001%. High current discrete output circuit gives higher bridging power. With 4 ohms bridged, up to 180W of power is enough to make the sound more complete and fuller. This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.
