AudioSource Amp One/A 160-Watt Stereo Power Amplifier with Internal Bridging

AudioSource Amp One/A 160-Watt Stereo Power Amplifier with Internal Bridging

Product Description
Amazon.com Product Description
Not everyone wants or needs a single feature-loaded surround receiver, which is where the AudioSource Amp One/A 160-watt stereo amplifier comes into play. A favorite of audiophiles everywhere, the device is built to deliver powerful music, pure and simple, with few gratuitous extra controls to get in the way. Listeners can use the Amp One/A as an independent stereo amp (80 watts x 2) when used with a preamp, or as an adjunct amp for a low-powered surround receiver with preamp outputs (it delivers 200 watts of mono power). Combine the Amp One/A with an additional monoblock amp and a preamp and listeners can powerfully drive two front left/right speakers or two rear speakers, further clarifying each channel to create dynamic, high-end sound. To connect additional components to the amp, use the included line-in jacks (for connecting to a source such as a receiver, CD player, or preamplifier) or the line-out/thru jacks (for creating a multi-amp setup). It's also simple to switch between stereo and mono modes thanks to the bridging switch.

The amp features a precise frequency response of 20 Hz to 20 kHz and total harmonic distortion of less than 0.04 percent--barely enough to register to the human ear. It also boasts color-coded five-way binding posts that make it easy to hook up stereo speakers. And at 16.5 by 2.38 by 11.62 inches (W x H x D), the device should fit comfortably in most rack mount or home entertainment setups. In addition, the Amp One/A is covered by a two-year warranty on parts and labor.

Disapointing.......2007-05-12

We purchased this amplifier to drive a 5-ohm load based on the manufacturers claim of a low impedance 4-ohm capability. The unit arrived dead out of the box. Amazon promptly credited us and provided a return label. We purchased an identical amplifier locally because of time constraints. When connected to the 5-ohm load it worked but got extremely hot and we shut it down. We double checked the ohm load and it was 5-ohms. We returned the amp and purchased a completely different amp in slightly higher price range from a different manufacturer. The new amp worked fine. The audiosource is OK for a basic, small 8-ohm load and does not have the low impedance characteristics advertised by the manufacturer.

A great buy.......2007-04-14

I have owned two of these amps for almost a year now and I am very fond of them. I have four bookshelf speakers that were being power by a stereo receiver. This stereo receiver bragged that it produced 100 Watts per channel for four channel. So, supposedly each of my speakers was getting 100 Watts of power. However, power in the audio industry is not well defined. Believe me as I am a physicist, they are pretty wacky in the audio business. To calculate power, one uses the formula Power=V^2/R, where V is the RMS voltage and R is the resistance of the circuit or load. Sorry this is getting a bit technical, but the moral of the story is the audio industry feels free to choose R at will. This means they can claim any power. The sad thing is it is legal to so do. Anyway, back to the review. I bought two of these amps to power my four speaker. That means I am running 80 Watts into each speaker. This should be quieter than my old receiver, but it is not. It is much louder because these amps actually put out a real 160 Watts as opposed to my old stereo receiver which most likely put out 50 Watts per channel.

Also, the signal to noise seems excellent. These are the first amps I have owned where if I run a clean signal in and turn the volume all the way up, I do not hear a hiss coming out of my speakers. In fact, they recommend that one keeps the amps turned all the way up at all times and simply adjust the input signal volume. This is what I do an it works well. I am very satisfied this this product.

Good Value, Prompt Delivery!.......2006-11-10

This is a top rated audio component. Price was equal to the lowest I could find online. Delivery was as promised (actually a day early). I chose Amazon for this transaction because of past experience and reputation.

Excellent value and sound; one of the best deals in amps!.......2004-12-12

I have been an audiophile since I was a teen (over 20 years), having owned some truly high end amplifiers like Bryston, Audio Research, and currently in my main system, a McIntosh MC162. All phenomenal amps. I also happen to own an AudioSource AmpTwo and an AmpOne, both superb amps for the money. The only difference with the AmpTwo, is that it has left and right channel lit VU meters that measure watts output and 'headroom' in db units. Very cool indeed! Other than this, the AmpOne is identical to the AmpTwo. The AmpOne is set up in my home office connected to higher end equipment like Parasound and a Denon HDCD player. My speakers are the very venerable and respected bookshelf horn speakers, the JBL HLS-610, which is very well balanced and revealing of source material and equipment. And lastly, I run fairly expensive 'StraightWire' interconnect cables between my components. That said, I have been blown away by the quality and neutral sound of this amplifier! The amp sounds detailed, accurate, warm, sweet, and powerful - attributes usually found in more expensive high end amplifiers as mentioned above, usually costing thousands of dollars! Quite an amazing feat for this solid little affordable AudioSource that satisfies even high demand audiophile ears like mine. Moreover, I have tested the AmpOne and AmpTwo while driving difficult power hungry loads, such as Magneplanar 4 ohm speakers, and they performed beyond my expectations. Kudos to AudioSource for providing one of the truly 'best bang for the buck' deals in stereo amplification out there! I highly, HIGHLY recommend this product.

VERY good amp for the money.......2003-07-23

very flat sounding. i'm tired of people comparing other amps and thinking they are better for one reason or another.. but thats consumer audio for you... the goal should be to have flat sound that is as true to the origional recording as possible.

at any rate, this amp doesnt stray much in frequency response across the spectrum, has practically no noise (most notably, you can turn it up all the way with no audible hiss at all) and very low harmonic distorion.

the only real downside to this amp (for this price.. or mabye even a much higher price) is that it would have a pretty hard time driving some of the bigger floorstanding speakers.. but if you have a good subwoofer, who cares, right?

Product Description

AudioSource power amps provide high sound pressure levels, as well as subtle details, with accuracy and transparency. You won't find better sounding amps at anywhere near the price. A torodial power transformer keeps stray magnetic fields to a minimum, and the discrete output devices ensure pure signal fidelity. Separate channel level controls allow for individual adjustment. A defeatable peak limiter circuit protects speakers from distortion at high volumes, and an auto-on circuit powers up the unit with a preamp signal and powers it down when no signal is present. AudioSource amplifiers, with dedicated power supplies, have dynamic power reserves lacking in receiver combos. AudioSource separates are better able to isolate individual parts, providing a clean signal path. AMP One/A is extremely easy to set up and can be configured to function in either stereo or mono modes. One pair of speakers can be used with this amp. Its Power Output is 80 watts per channel and 200 watts monobridged. You will certainly enjoy the value and quality of your AudioSource AMP One/A for many years to come.

First rate amplifier.......2007-02-15

I am using this amp in a biamp setup to drive only the lower frequencies, so I have not examined it's performance as a "stand alone" unit. It appears to be nearly noisless and gives a very clean and punchy low end, which is what I was looking for. Bargain price for such a fine amp.
