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!

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!

I mainly purchased this mini audio amp to replace the one I currently have because of buzzing noise it was making for the living room TV. It sounds better without that annoying buzz and does the job well. That's why my living room TV sounds better when I hooked it up to the RCA audio output behind the TV.

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.

I have purchased several small Kinter amps and they all work great. This one is no exception. I have it in my shop and it has plenty of power for a 3 1/2 bay shop. Sounds good to me, and none of my amps have failed with lots of use.

I've used this for about a week streaming music from a PC via the 3.5 audio output and other than a 5 second or so delay while it's powering up it works great for me. It's connected to six home speakers and a powered sub (no other amps) and in a shop where it gets loud, we don't raise the volume beyond 50%. Audio quality is pretty good for the $30 spent

My use for this item is as an audio amp for an XTL1500 mobile radio used as a base station at my computer desk. When hooked up to a standard mobile speaker indoors, the fidelity and audio just wasn't to my liking, too much treble and too much background hiss for p25 audio when it is receiving. Just wasn't clean and reminded me of a cheap scanner which this is not. First thing I did when I got it before even hooking it up was take it apart and rip out the Blue LED's. It is gimmicky and cheap looking. All we need is a green or red status LED. Hooking it up was easy. I hooked the amp up directly to the speaker out on the radio (Motorola prefers you don't do this, just dont turn the radio AND amp all the way up or you will fry the speakers and possibly the amp). I found that radio volume at 55-65% works best. I turned the treble all the way down and bass up halfway and it has really cleaned up the audio to my liking. I now just use the amp as volume control and I love it. I also got a set of Pyle 200 watt speakers to go with it which work great. I imagine this will last a very long time being used like this considering its just driving police and fire chatter and not music for hours.

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.
