Audio Science review!

Conclusions
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.

The amplifier is not for everyone though. Power level is modest as compared to competitors. And you have that large external power supply. My wish is another version of this amp with built-in power supply, motorized volume control with bridge mode standard. For now, we need to celebrate one of the most important development in delivering transparent, high fidelity amplification to audiophiles in a very attractive package.

It is my absolute pleasure to recommend the Topping LA90. History is made on this day folks!
