The amp boasts a precise frequency response of 20 Hz to 20 kHz and total harmonic distortion of 0.02 percent. Additional features include A, B, or A+B speaker selector switches, front-panel mounted volume and balance knobs, and five-way binding posts that work with both bare wire and banana plugs. Plus, at 16.5 by 2.9 by 9.25 inches (W x H x D), the device should fit comfortably in most rack mount or home entertainment setups. All AudioSource amps are backed by a two-year warranty on parts and labor.

Content: Amplifier works well for a single audio source. This unit has an auto on feature that responds to the presence of an audio signal at the input.
Summary: Stereo Amp

Content: We have two reference systems in the home plus digital or analog over ethernet feeds to all of the other rooms. Speakers tend to be high end, source material ranges from digital music fed to dac's or cd's. I have two AudioSource 100's, one in the kitchen driving Energy's and one that drives a set of B&W's on the porch.

Totally devoid of musicality. This amp will kill any source signal you put in it. Compared to any amp we've had in the past 40 years, this is the worst. The sound has nothing going for it, 0 energy, no low end, sounds like it compresses music, no soundstage, no rhythm, just plain boring.
Summary: Take a pass on this one

Content: A couple of years ago I was looking for a stereo amp to power 8 sets of ceiling speakers in my home. I had already installed impedance matching volume controls so I was not overly concerned about the amp getting dragged down with a 2 ohm or similar load. My choices narrowed down to an Onkyo M-282 or the Audiosource Amp 100.

The Onkyo put out 100 watts per channel and the Audiosource did 50 watts at 8 ohms. Nod to the Onkyo

The Onkyo had an Amplfier Protection Circuit and the Audiosource had a fuse. We will come back to this point.

The Onkyo was $200 and the Audiosource was about $90 at the time. Nod goes to the Onkyo because it just had to be better at the price difference.

Last week, after just over 2 years, the Onkyo rolled over and quit. After way too much time on the phone at Onkyo Customer support, it became clear to me that there was no repair route that would be less than the cost of a new Onkyo; the culprit was the "Amplifier Portection Circuit".

Since the Onkyo was now a doorstop, I decided to try the Audiosource 100 and since they were 50 watts at 8 ohms or 160 watts bridged, I bought two from Amazon. They got here in 4 days and I took one out and inserted in into the system. It is now playing all 16 speakers at a level of sound volume and quality that is way beyond what the Onkyo did at 3X the price.

Did I mention that I set one of the amps up in 50 watt stereo mode? There is no need to use both amps in mono mode. The sound is very impressive.

Onkyo is dead to me and Audiosource has a new and happy customer. I only wish I had taken the chance before blowing good $$$ on the Onkyo M-282.


Summary: What I should have bought in the first place

Content: A quality product at a good price. I wish the A/B switch would turn on both sets of speakers instead of either/or--if so, I would have given it five stars.
Summary: A good amplifier
