4.0 out of 5 stars Inexpensive entry-level amplifier, December 27, 2013
This review is from: Lepai LP-2020A+ Tripath TA2020 Class-T Hi-Fi Audio Amplifier with Power Supply (Electronics)
I have been using the Lepai amp for almost 2 years. There are good and bad things that I noticed. Below is my summary of the Lepai mini amp:

1) This amp is really inexpensive. If you cannot spend more than 20 bucks then you may want to take a close look at this amp.

2) The sound quality albeit at low volume is pretty decent. This amp uses the TA2020 chip set which does offer quite low distortion at low volume.

3) The amp has tone controls so you can fiddle with the sound to some degree.

The BAD:
1) You'll be hard pressed to drive a pair of low-sensitivity or 8-Ohm speakers to decent volume with this amp. With an 8 Ohm speaker, you get clean sound to around 5 Watts only. If you crank the amp up to 10 Watts you'll already hit 10% distortion. With 4 Ohm speakers you can get up to 10 Watts per speaker. In fact, the wattage rating of this amp (2 x 20 Watts rms) is truly false. The power supply that comes with this amp gives 2 Amps at 12 Volts. At a power efficiency of 90% you'll get 2 x 10 Watts rms at the most. However, if you have some fairly small speakers then you may be fine. Otherwise, spend a little more and buy another amp.

2) This amp DOES NOT connect to many newer TVs which often no longer have analog RCA outs. Instead you'll either need to get an SPDIF-to-RCA converter or an amplifier such as the Amphony 250 or similar model that has an optical input which is compatible with TVs. My TV luckily does have RCA outs but be sure to check if your TV does.

3) The enclosure of this amp is fairly bulky and not exactly high quality. I opened up the enclosure and found that most of the interior is empty. What a waste of space! Also, there are some gaps and areas where Lepai could have spent a little more attention to detail in terms of quality. The knobs are fairly basic too and tend to come loose.

4) The rear speaker connector easily snaps out of its socket and doesn't accept thicker speaker wire easily. So you'll have to stick to fairly thin speaker wire.

To summarize, if you really cannot afford more than $20 on an amp then the Lepai is a decent choice. But don't expect the amp to drive larger speakers.

Thanks for your review, and based on what you said, not sure this amp is for me unfortunately. I actually do have a couple of Sony 8 ohm speakers I wanted to hook up to this for use on my digital piano. Since I don't know much at all about amps and ohms, what do you think would be a decent amp for 8 ohm speakers? What power output should I be looking for from the amp?

Thanks again.

If you are looking for a small form-factor amp then the Amphony 200 and the Dayton 100 would be some decent amps that can drive 8 Ohm speakers well.

Between the Dayton and the Amphony, I would vote for the Amphony. It is less expensive and super small. I got one recently to power a pair of 8-Ohm speakers. It comes with a 36 Volt power supply (the Lepai comes with a 12 Volt supply) and drives my 8 Ohm speakers very well.

i would still recomend this amp despite the power supply. just purchase a 12 volt (or even better a 13.8 volt power supply) that is 5 amps. garentee it can make those speakers loud. I have run this with a 16 ohm load and it was so loud that it was rattling the whole house with no distortion. the power supply is like 8 bucks.

Link to power supply?

This review is spot on. I purchased this amp to hook up to my desktop and a pair of Infinity Primus 140 Bookshelf speakers. The speakers are rated for 10-100 watts 8 ohms and about 86db sensitivity. Decent quality speakers. I run ITunes, Pandora and computer game sound through them. This amp works until the dial is about 65% louder than that the sound falls apart. For $20 its great unless you want to pump it up. If you want 20 per channel get a 50 per channel minimum. For audiophiles this amp will not work for you. I used 18 gauge wire and it fit no problem I'm sure 16 gauge would fit. In honesty you might get to 75% around before it becomes unlistenable. I have a particular ear.

I have an LP Player with a ground cable? Am i able to use the ground cable on an amp like this one as.
Example is: PYLE-PRO PP444 Ultra Compact Phono Turntable Preamp Please let me know.

I use this power supply with my LP-2020A+: Replacement 60W 12V 5A Adapter Charger for Benq LCD Monitors and it gets good and loud with no distortion. I'm running through a pair of 1977 Teledyne AR15 speakers and it sounds fantastic!

The math just doesn't work on the included power supply: this is a 20 watt x 2 channel amplifier, so you will need at least a 40 watt power supply to run it cleanly, but the wall wart I got with mine is only capable of 24 watts.
