Topping Comes Up With A Powerful Power Amplifier: Topping LA90
Topping is one of those brands whom we trust with their premium desktop gears. In their catalog, we have got DACs, Headphone Amplifiers, Pre-Amplifiers, and many more desktop gears. Today, Topping has released a brand new power amplifier, the Topping LA90. It’s their flagship power amplifier that is designed to accompany premium products including the D90SE+A90 stack, the Pre90 Pre-Amplifier, and more. The main attraction of the LA90 is its set of three inputs where we can connect three different sources at once and select between them as required. All three of these support both XLR and TRS inputs. LA90 can be used in both Stereo and Mono modes, easily switchable between the two modes. LA90 is launched with a price tag of 899$, you can check out more details here.
Topping has got years of experience in designing premium audio gears. They have treated the latest LA90 with stunning build quality. The chassis here is made up of high-quality aluminum alloy using CNC machining processes. This frame houses two huge heat sinks at the sides of the. With the help of these heat sinks, the LA90 works perfectly normal and doesn’t heat up a lot.
The LA90 here is an extremely powerful amplifier with a power rating of up to 110Wx2. Topping LA90 not only has a powerful output, but it also maintains ultra-low distortion and clean background in the output signal. The amplifier achieves as low as 0.00009% THD+N ratings @ 4Ω of load. Topping LA90 can be configured to work either in traditional Two-Channel Stereo mode and it can also be used as a mono amplifier. In mono mode, the LA90 produces highly-powerful output(up to 220W x 8Ω).
