New TOPPING LA90 Power Amp


When it comes to home HiFi, one of the most important elements of a system is the amplifier. Amplifiers are inherently noisy when it comes to signal output – when you’re pushing out large amounts of power, electrical noise is generated as well. Until now that is.

The new TOPPING LA90 is changing the game in regards to THD+N (Total Harmonic Distortion + Noise). THD+N is a scale used for expressing the sound quality of an audio power amplifier. Most average power amps have a THD+N of around 0.0008%. The LA90 takes that all the way down to a THD+N of 0.00007%. Yes, there’s an extra 0 in there!

The TOPPING LA90 can operate in both stereo two-channel mode or in a high-power mono mode. It has a high-precision CNC-machined all-aluminium housing with a utilitarian but prestigious aesthetic.

With a power output of 110W x 2 @4Ω in stereo mode and 220W x 1 @8Ω in mono mode, the LA90 has enough power to drive a wide variety of speakers. Thanks to the unit’s impressive performance, you’ll only hear a good kind of noise from this amp and one that’s free of distortion.

FYI. Chinese amps grossly overstate their power using total power at 10% distortion. ASR has measured this amp as 56 wpc @4ohm, and 36wpc @8 ohm. Not a power house at all. Gee

Would love your thoughts, please comment.x
