AudioSource AMP-100 2-Channel Bridgeable Stereo Power Amplifier

A few points from my short time with this product using it as an amp for my computer pushing two bookshelf speakers-

-I read all the other reviews, and the instructions so I use input 2 and don't have any problems with it turning itself off.

-The binding posts in the back are rather hard to maneuver around if you are using larger gauge wires.

-Power off isn't delayed or anything fancy like on other receivers, it's just a hard switch so you get the little "fwwoomp" noise.

-It is constructed very well and doesn't seem to heat up at all.

For the price, it is a great little piece, but it does seem a little low on power (couldn't push my towers well at all) but they do make a more powerful version.

Well, it's acceptable, given the price. I exchanged the first one Amazon shipped me, because even input line 2, and even when set to "Manual" mode, was not turning on when a quiet input signal was actually present.

The second one shipped to me works better. You definitely can only use line 2 if you might ever have a quiet signal (such as a pianissimo passage or rest in the middle of a piece!) and don't want your amplifier to decide all on its own to suddenly turn off, and then miss some music before it decides to turn on again.

We are using it to drive two bookshelf speakers with a single input line from our iMac.

I bought this power amplifier for my desktop computer to play a small pair of external speakers (B&W M-1's). It sounds great and has been working flawlessly for several weeks. It easily connects to the computer's stereo 1/8" analog audio jack (either headphone jack or line-out jack). Besides the attractive price it has a very nice power savings feature whereby it turns "off" and "on" by itself. Specifically, the power amplifier automatically goes into standby (i.e. very low power mode) after 10 minutes of not having detected any signal from the audio source (i.e. the computer). And it automatically turns "on" instantly when it detects an audio signal. So, basically you do not have to remember to turn this power amplifier "off" or "on". Note: To connect everything I only needed some speaker wire and an inexpensive audio cable available at any Radio Shack or other electronics store having a 1/8" male stereo connector on one end and RCA connectors (left & right channel) on the other end .

Suprised by the performance.Quiet and dynamic...tock the cover off ' it's well built. Just a clean amp with a balance and volume control. The automatic (Can be defeated)
swithing for the poweron and inputs can be annoying, but make sure the the input source has enough gain (output) and use the volume on the amp.Ipod needs to be at full volume for eample . a real deal!

The Amp 100 provides good amplification and is extremely simple to operate, it took me two minutes to plug everything in and get started. I would have liked bass and treble control knobs but you can regulate that from the source anyway.

NOTE: to all those complaining about the auto-off feature that turns the amplifier off whenever no signal is detected, it can be turned off via the switch in the back. Idiots.
