Topping PA5 II Speaker Amplifier for Compact Desktop Audio Enthusiasts | Topping PA5 II Fully Balanced Amplifier Best S

A Complete Look At Features

Fully Balanced Structure and Pure Sound Quality

The PA5 II and PA5 II Plus adopt a fully balanced structure and an innovative Class D amplifier circuit, delivering high power output with minimal distortion. Our expert engineers have fine-tuned the system to ensure clear, deep, and noise-free audio performance.

Extremely Low Distortion

The distortion levels of PA5 II and PA5 II Plus are exceptionally low, comparable to those of high-end DACs. When outputting 5W under a 4 Ω load, THD+N is as low as 0.0004%. Under an 8 Ω load, it drops to 0.0003%. This ultra-low distortion enhances your music experience by eliminating audible noise, ensuring that every note is pure and faithful to the original recording.

High Output Power

The PA5 II Plus can deliver up to 140W x 2 for a 4-ohm load at 10% distortion and 125W x 2 at 1% distortion. The PA5 I can also produce a robust 100W x 2 for a 4-ohm load at 1% distortion. This high output power, combined with minimal distortion, ensures that these amplifiers are powerful enough to drive a wide range of speakers and meet the demands of various use occasions.

Comprehensive Circuit Protection

Your PA5 II series amplifiers come equipped with extensive protection features, including overvoltage, undervoltage, short-circuit, overcurrent, and overheating protection. The amplifiers operate silently and seamlessly, providing peace of mind even during power outages.

D10 Balanced Partner

D10 Balanced offers high-fidelity USB decoding and a TRS balanced output, making it an ideal partner for PA5 II series amplifiers. This combination seamlessly adds a high-performance USB input jack to your PA5 II amplifiers, optimizing performance when only USB input and amplifier output are required.
