TOPPING LA90 Ultra-high Performance Power Amplifier 90W*2 110W*2 220W*1 AMP 3*XLR/TRS Balance Input Stereo Mono 2 Step Gain Settings Power Amplifier (black)

Product Information

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.

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. 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 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. 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 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:-

Balanced inputs

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 It is clear that Topping engineers are bringing their expertise in designing ultra low noise and distortion in headphone amplification to power amplifiers. As such, they have outdone every amplifier I have measured in that regard, getting ahead to capture the #1 position with a large gap to #2 choice. Accidents, abuse, misuse, improper installation, problems with electrical power, acts of third parties. In terms of inputs, both models are equipped with three sets of balanced inputs: XLR and TRS, offering versatility in connecting various audio sources. Gain Settings: A Closer Look 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.

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.

Any item returned incomplete or with physical damage such as scratches etc., excessive signs of use, or abuse will not be accepted for return. If 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.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 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. Damage due to user negligence, accidents, disassembly, waterlog, misuse, abuse, alterations or vandalism. 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! 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 LA90D
