I am very satisfied with the Topping LA90D power amplifier. I purchased four units to build an 8-channel active speaker setup. They are very solidly built and have a beautiful, professional appearance. The price-to-performance ratio is excellent. Their performance is outstanding. The measured specifications show exceptionally good results, with extremely low distortion figures. This results in a very pure sound without any coloration. In our opinion, this amplifier is highly recommended for use in a top-quality audio setup. The Topping LA90D performs as well as — and often better than — many other power amplifiers that are significantly more expensive.
