AudioSource AMP-100 2-Channel Bridgeable Stereo Power Amplifier

I bought this unit to power an Energy 2.1 TV sound set up. I have a high-end reference system in my living room with top of the line NAD components driving Energy 22.2 speakers, and Straightwire cables and interconnects. The amp 100 which costs 10% of the NAD amp is as clean, but not as transparent or as warm, but for under $100 it is great. All the bad reviews about the auto switching are bogus, it is stated in the manual to use the 2d input if you have only one device. I have the digital cable box connected to a DVD player which then is connected to the input 2 of the amp, with an internet radio connected to input 1. When I turn on the radio, the amp switched to input 1 perfectly and quickly. Anyhow, the auto switching was important to me, as is the AB speaker selection - I have the sub wired to output B. When I turn on the TV, the amp comes on, and the Energy sub which also has auto switching comes on. Later when I turn the TV off, all goes off too. I am very satisfied with the sound (of course, the Energy speakers help here) and that the amp performs exactly as I wanted re the switching.

This has autosensing but you can flip a switch on the back and make it into a manual amplifier as well. Autosensing works best if you use line 2 input as your primary. Smooth response curve and does a great job.

I bought this to replace an unreliable NAD amp that was beginning to drive me nuts. The NAD sounded great, when it was working properly. I just needed something really basic to plug a Vestax mixer and two Technics 1200's into, as well as the occasional laptop. I'm running this with a set of 15 year old Boston Acoustic speakers and it sounds great. Really impressed for the price. Would reccomend this to anyone needing a solid amp at a great price.

I bought the AudioSource Amp 100 to replace a 30-year-old Harmam-Kardon that had died - I used it to make cassette copies of old phonograph records. The Amp100 does accept the signal from my turntable and pre-amp and puts the sound on the speakers, proving that there was nothing wrong with my system but the dead stereo amplifier. However, although the Amp 100 clearly has stereo output jacks, the signal there will not provide anything useful to the cassette deck. Way down in the fine print of the instructions I discovered that this "output" is referred to as a "pass-through", which apparently means it is unamplified. Phooey!

This amp is powering some remote speakers, where we wanted a seperate volume control. It's cheap, works great. My only complaint is that, while you can hook up two pairs of speakers, it will only power one at a time! This is not an issue for what we're doing with it, but came as a minor surprise.

Good product at a great price.
