Descriptions:

Power, Precision, and Purity
The Topping PA5 II Compact Desktop Amplifier is all about delivering a pure, balanced, and immersive audio experience right on your desktop. Engineered with a fully balanced structure and an innovative Class D amplifier circuit, it aims to transform your listening sessions into an unrivaled sonic journey. Its impressive power output, comprehensive circuit protection, and compatibility with other high-fidelity devices also ensure a smooth, worry-free user experience that adapts to your unique audio needs.

Fully balanced structure
Delight in the purity of sound with the fully balanced structure of these amplifiers. Engineers have tuned these devices for clear, clean, and deep sound with no audible noise floor. The fully balanced structure effectively eliminates the common issues of hum, noise, and ground loops.

Distortion as low as an excellent DAC
Relish incredibly low distortion. The PA5 II and PA5 II Plus achieve a THD+N as low as 0.0004% under a 4 € load when outputting 5W and 0.0003% under an 8 Ω load. This enhances your music listening experience, making every beat count.

High output power
Whether you're driving small speakers or large, these compact desktop amplifiers have got you covered. The PA5 II Plus delivers up to 140W × 2 for 4-ohm loads at 10% distortion and 125W × 2 at just 1% distortion. Similarly, the PA5 II can output 100W × 2 for a 4-ohm load at 1% distortion.

Comprehensive circuit protection
No more worrying about sudden power outages or short circuits. The PA5 II series provides complete protection for overvoltage, undervoltage, short circuit, overcurrent, and overheating. You can focus on your audio, knowing your gear is safe.

PA5 II vs PA5 II Plus?
While the Topping PA5 II and PA5 II Plus share a significant number of features, there is a critical difference in terms of power output. The PA5 II Plus takes the lead with a maximum output power of up to 140W × 2 for 4-ohm loads at 10% distortion, or 125W × 2 at 1% distortion. This is compared to the PA5 II, which provides a maximum of 100W × 2 under the same conditions. This power difference gives the PA5 II Plus an edge for those seeking a bit more amplification capacity for their audio setups, while the PA5 II may be sufficient for users with less demanding power needs.
