## Features

- About this item
- 【Fully Balanced Amplifier】The newly developed Class D amplification circuit uses multiple novel optimization techniques to fully push the performance and output power to the maximum. The new circuit provides crisp, clean and deep sound with completely inaudible noise floor. The fully balanced structure makes PA5 no more hum, no more noise, no more ground loop.     【Distortion Is as Outstanding as DAC】<0.0005%@4Ω 5W; <0.0004%@8Ω 5W. The distortion of PA5 is as low as that of DAC. Even in the vicinity of the commonly used 20W, PA5 can achieve 0.0003% THD+N under 8Ω load.     【High Output Power】PA5 could output 140W×2 at 4ohm load, 10% THD+N. In higher standard of THD+N of 1%, outout power will be 125W×2 at 4ohm load. The high output power and low distortion on load are sufficient for most speakers and applications.     【Low distortion & Noise】Zero pop noise or thumping during turn-on or turn-off. Over-voltage, under-voltage, short-circuit, over-current, over-heat protection are complete.     【PA5+E50+L50】This is a fully functional combination. When you need a more comprehensive system, we recommend a combination of PA5 power amplifier, E50 DAC, and L50 headphone amplifier. In this way, there are corresponding equipment from the digital audio source to driving speakers and headphones.

### ⭐⭐⭐⭐⭐ 







  
  
    If the power is enough for your speakers, you may have found your last amp.
  

*by M***I on Reviewed in the United States on May 2, 2022*

The sound is just what is on the recording or the stream without any additional noise or distortion. If you look at the Audio Science Review, you will see the amp is among the very best available for a clean, transparent  sound.  Wonderful highs, without any glare. Deep, controlled bass. Simple to use. Occupies a minimal amount of space.  I use it to drive Polk LSiM 703 bookshelf speakers to very loud volumes in a room 20 x 20. (Sensitivity is listed as 88dB.)Sound is superior to Cambridge Audio, Rega Brio, and a whole series of Class D amps I have tried.Cons - no remote, pretty plain looking - it's not going to knock your audiophile friends' socks off (at least until they hear it).  May not be enough power to drive floorstanders or very inefficient speakers.Recommended without reservation, especially considering the price. On sale, it's about the same price I paid for a Marantz 1060 fifty years ago. We really do live in a golden age for electronics.

    Great compact amplifier delivering transparent audio
  

*by D***D on Reviewed in the United States on June 19, 2022*

This amplifier is a compact, transparent amplifier. It's a perfect fit for a moderate desktop or bookshelf stereo system. I use it to drive mid-sensitivity Polk R200 bookshelf speakers in my studio, and it does the job perfectly. If you want a stereo amplifier that doesn't add any color to your sound, this amp is a great fit.The amp is a bit overly simple and opinionated with only balanced TRS inputs, however I have tried single-ended input with RCA to TRS single-ended adapters and it works fine. An auto-on/off feature is also missing, which would have been nice to have.Pros:- Plenty of power.- Transparent audio output.- Compact with no heat issues and no fans.- Nice feeling volume knob.- Good build quality.Cons:- No auto on or off feature.- Large proprietary power brick.- Only accepts balanced TRS input, requiring additional adapters from most other equipment.My order was sold by Aoshida, and they have so far provided great service.

    Would not work, parent company Apos did not respond
  

*by D***K on Reviewed in the United States on April 19, 2022*

Hooked this up with a Topping DAC and got no sound. Contacted support after checking and triple checking all connections. Reached out twice to Apos through 2 different modes, no response in over a week. Thus returning the equipment and going with something else.Like others, found it on ASR, but really becoming less of a fan of that site
