Summary: I 've had this over a year and it has worked flawlessly. I use it in my office with my computer and iPhone and it has plenty of audio power for the job. I paired it with a Polk PSW-10 subwoofer with two ancient Radio Shack speakers and it sounds great.
Excellent driver of bookshelf or even floorstanding speakers but the front headphone port is mediocre at best

Summary: It's good but not perfect. I've been using it regularly for about a year now. The protective storage bag that's included makes it perfect for transporting. I have used this to drive 2 Polk floorstanding speakers and a PSW 505 12" sub, and it performed flawlessly.
Summary: I'm no audiophile. But this little amp is just right for what I needed. I had a set of Bose Acoustimass (with sub) that had been sitting idle for years. I hated to throw them away. So when it came time to buy new speakers for my desktop at work, I spent the extra money and bought the AE N22.
Great product but still can't justify the price tag.

Summary: Expensive as hell but top quality. I've got two Polk audio in-wall speakers in my bathroom and was using a Pyle POS to power them. I had all kinds of noise problems and the speakers sounded distorted. Gave this guy a whirl and all of my problems are cleared.
Summary: Pros It works great with Sensitivity (1w/1m): 85dB pair of Speakers I am using. It has plenty of power to spare for computer desktop distances and I run mine from 1/4 to 1/2 turn on the volume knob.
