Unbelievable Sound on a Budget!
I recently found some hidden gems at Goodwill - a pair of bookshelf speakers in need of a worthy amplifier. After scouring the market for an affordable option, I stumbled upon these gems. Not only were they the most budget-friendly amplifiers around, but they also boasted the credibility of a name brand op-amp, Texas Instruments! To be honest, I didn't set my expectations too high, but oh boy, was I in for a pleasant surprise! This amplifier exceeded all my assumptions and then some. At this price point, it keeps things simple without unnecessary frills, but let me tell you, when I compared it to my $600 Yamaha Amplifier in "Pure Direct" mode (which essentially means no Yamaha DSP magic), this little powerhouse held its ground remarkably well. The music reproduction is phenomenal, matching the performance of its much pricier counterpart. The clarity, depth, and overall sound quality left me in awe. I can't stress this enough - for the price, this amplifier delivers an astounding performance. If you're on the hunt for an affordable yet impressive amplifier, look no further. This is the real deal, providing exceptional value for your money. Don't miss out on the musical magic this amplifier has to offer! Highly recommended!

Great amp!
Easy hook up, used for computer rear bookshelf speakers. Room sounds great!

Tests at 7 watts per channel, but works well for PC Audio
Someone gave me a small pair of speakers, and I needed an amplifier to drive them. Before putting it in service, I tested it into a dummy load on a Rohde & Schwarz UPV audio analyzer. Frequency response is reasonably flat. The tone controls give a lot of boost and modest cut, which is nice for getting more body to the sound on small speakers. The continuous RMS power measured at clipping is 7 watts per channel. I would imagine the power brick is the limiting factor. Overall, a nice little amp that uses almost no juice when idle and is adequate for computer sound when I want to watch a video online.

Highly recommended for its purpose - quality moderate-power amp
For what it costs, this is a total no-brainer if you're looking to power a single stereo channel with moderate power (wattage). Sound is very passable - and the tone controls help here. Great input section (both RCA and 1/8" jacks), and the blue light isn't obnoxious. For $20, this is simply an incredible value. I installed it as a sub-zone amplifier for a whole-house controller, allowing me to use fixed volume for the line out on the controller to pass signal to this amp and use a set of speakers for which we didn't have a dedicated controller channel. It works perfectly and drives the speakers (located outside) very nicely at about 30% on the volume pot. Such an elegant solution all around.

Good for the Price
What do you get? Mine was fully functional, without unexpected performance issues. Both channels evenly balanced and clear. Used for near field monitoring output volume satisfactory with included power supply. For larger spaces an upgrade would be better. Sound is clear and not harsh or brittle as some cheap class D can be. The housing is metal though thin, knobs are cheap and unattractive. The tone/direct switch functions well but feels cheap and I believe is something that will eventually fail. The tone controls seem well voiced. The direct setting may seem rolled off in the bass. However it is far more detailed with better sound staging in this mode. I would suggest a separate eq be used. With tone control the sound is not bad and may be more pleasing for people. Mine is for mobile music production, I appreciate the clarity of direct. The speaker spring clips are good, and easily accommodated 16awg wire. I can’t speak to the longevity of this amp with the entry level toy-like controls. But the price balances that out.

Amazing sound from a small, lightweight amplifier!
This little (and it is very small and lightweight) amplifier produces remarkably good sound, and lots of it. Since it uses a Class D output stage, it's highly efficient. In fact, according to the manufacturer, it makes 20 watts per channel RMS audio power. Since its power supply only provides 36 watts of power for it to run on, two channels of 20 watts each, or 40 watts of output is remarkable for a device that only consumes 36 watts of electricity. That's 133 percent efficiency! This claim aside, the amplifier works well, sounds great, and I highly recommend it if its power rating is appropriate for your use!

Excellent Economical Solution
I needed to connect my wall and ceiling speakers to my new bedroom TV which, unlike my old one, did not have speaker jacks. This amp allowed using either the optical or headphones and I opted for the headphones so that the TV volume still controlled the external speakers. I set the volume on the amp where I needed it and haven't touched it since. The speakers sound excellent. The amp is on 24/7 in a 24x35x18 cubby behind the TV and it is never warm to the touch. I get the occasional random pop through the speakers when the TV is off but there are plenty of unrelated possible sources that I have not yet had time to investigate. I knew this speaker connectivity problem was coming one day and this unit was a super cool and easy solution.

Not as nuanced a sound as Tripath TA2020-020, but an amazing value
For a simple amp that will drive some speakers at a really good price, this is terrific. Sound is not as nuanced or as enjoyable as the Tripath TA2020-020, but it's really a good performer, and amazing at this price. This is a fantastic upgrade for your built-in tv speakers, or a good starter system. It's great for the garage or dorm room if you don't have money to toss around, but have some speakers to use. If you can find one at a better price, though, get one with the Tripath.
