The PA5 II and PA5 II Plus achieve a THD+N as low as 0.0004% under a 4 Ω load when outputting 5W and 0.0003% under an 8 Ω load. This enhances your music listening experience, making every beat count.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eHigh output power\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eWhether 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.\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eComprehensive circuit protection\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eNo more worrying about sudden power outages or short circuits.

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
