    It's a basic amplifier with good quality components and a neat assembly. Power rating at 50w/ch seems fair, but I got a 35w/ch Harman Kardon and a 30w/ch NAD that were more powerfull (and much more expensive) than the AudioSource. Sound quality is very good : it's neutral, clean and without audible noise, hiss or distortion, even at near full volume.

    I don't like the Auto-Switching inputs system, wich is too sensitive and keep switch between input 1 and 2 when there are quiet passages in music (on input 1). So I use only input 2. The same problem apply to the Auto-Sensing Power On, wich is useless for me.

    Overall, it's a great buy for the price.

    This is a solid stereo amplifier, physically and powerfully. It has a hefty weight and feel to it.

    I've only used this amp for a total of several hours at moderate to medium volume levels, but so far its lukewarm temperature at worst remains constant on the heatsink vents at the top and bottom. That was one of my concerns prior to buying it, and I'm glad that it's no problem.

    My sources are a laptop connected to an external USB DAC, which then connects to this amp. I haven't dared try playing music at 50% volume because it's already loud at the 3rd-4th volume knob's "dot". This is with 4-8 ohm passive bookshelf speakers, 90 dB sensitivity.

    A few cons:
    1) With my ears right up front to my speakers I hear a very small background "electronic" noise (not the hissing or humming noise), even when no audio is playing. Adjusting the amp's volume makes no difference whatsoever, even at its lowest setting. I thought it was due to my inexperience at setting up my 12 gauge speaker wires, but the same result occurs when I tested them with pre-made speaker wire that I've used with my previous PC speakers for 3 years. My previous speakers were dead silent up close. Only two 2 variables have changed since using this amp: the amp itself and the bookshelf speakers. I doubt it's my new Cambridge Audio S30 speakers that are highly regarded to be the culprit. Still, this flaw doesn't matter much since it's inaudible during practical listening positions.
    [Update] - Upon closer inspection the same noise emanates directly from the amp, and it's slightly more noticeable from there than from the speakers.

    2) At very low volume levels there's channel imbalance in the speaker output, with the right speaker being quieter than the left.

    An absolutely fantastic-sounding amp regardless of the price. Nice smooth top-end, a midrange to die for, bass extension that goes Barry White deep, and an open soundstage par excellence. One tip that cannot be ignored: read the manual! For normal stereo use, 'INPUT 2' is a must, as 'INPUT 1' is signal-triggered for standby use. Either way, it's insane sound quality for $100.

    Je suis très satisfait de l'achat de cet amplificateur. Il me permet de mettre en liaison la borne Airport Express avec mes haut-parleurs externes. Le signal de la borne provient soit de mon iMac iTunes ou de mon iPad. Ce petit amplificateur détecte automatiquement le signal provenant de la borne et s'arrête automatiquement lorsque le signal cesse.

    My rating is due to the fact that this AudioSource is relly what I need. So far I have no problems with it and I recommend it to anyone in need of this component The price is also very good.

    This is really a great product. The sound quality is great and it's a powerful little device.

    The only drawback I see is that the "auto switching" feature (between channel 1 and 2) is a bit too insensitive, so there has to be a good amount of sound on the first channel to avoid switching to the other, otherwise the sound cuts off. Since I use it for music which does have soft sounds, the result is not that great. But I still think it deserved 5 stars because it works really well.

    Auto on and auto switch inputs make this an easy to use inexpensive audio solution. Not for a complex system but for simple 2 input audio does the trick.
