Know before you buy
The discrete NFCA (Nested Feedback Composite Amplifier) design allows for exceptional signal purity and high current output. By using individual components rather than integrated circuits, Topping achieves an ultra-low distortion rate of less than 0.0001%, ensuring the output remains as close to the original recording as possible.
Yes, the LA90 supports a bridged mono mode. By switching to this mode, you can increase the power output to 180W into 4 ohms, which is ideal for driving more demanding speakers or achieving higher headroom in your audio setup.
No, the LA90 utilizes an efficient passive cooling system integrated into its high-precision CNC-machined aluminum enclosure. This design eliminates the need for noisy cooling fans, ensuring completely silent operation while maintaining optimal thermal performance.
The amplifier features three sets of combination XLR/TRS inputs. This versatile connectivity allows you to easily integrate balanced professional audio gear or standard TRS sources into your system.
The LA90 is designed to handle a variety of loads, with a minimum load requirement of 4 ohms in mono mode. It delivers 120W per channel in stereo, providing clean, stable power for most standard bookshelf and floor-standing speakers.
