Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply
Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply is rated 4.4392 out of 5 by 296.
Rated 5 out of 5 by from Quite GoodFor a 20$ amp it is fantastic, far exceeding my expectations!!! Some wanted a little amp to hide behind my TV to drive some Polk omw3 speakers, anything to sound better than those terrible things they call speakers on LCD/Plasma TV's. So it seems to put out a really good 5 watts per channel with the supplied 12v 3a power supply. " That's what came with mine" I will say that the tone controls kinda ruin the sound. Causes the midrange to become real thin bass gets muddy and highs way to bright. With tone controls off. Sounds great, maybe slightly, bright but its a very enjoyable bright. I was impressed enough to plug my martin Logan motion 12's and Denon DVD player into it and listen to some Eric Clapton unplugged. My jaw hit the floor not expecting to hear what I did... there was a decent amount of bass, not real controlled but pleasingly full. On to the midrange, very smooth and open but just a tad relaxed and surprisingly a Simi deep soundstage.. now to the highs, there are some artifacts apparent but still the highs are great. Overall the tonal balance of this thing is real good. Its not super clean but still really enjoyable but after all it is a 20$ amp and shouldn't be overly scrutinize on its sonic ability, but the fact that you can is astonishing for 20$. I will be modifying this guy for sure.. at least double the power capacitance with a eley or nichicon cap somewhere around 6.8-10uf should suffice, bypassing the tone controls for sure cause it doesn't need them, and replacing those junk output inductors with some Jantzen air core's. Mods should clean up some of the artifacts open up the soundstage a little and speed up/clean up that bottom end and drive with more authority... if you want something to play around with or maybe a good amp for computer or simply what I did add a more enjoyable sound to a TV, just buy it..you will not regret

Rated 5 out of 5 by from Lepai LP-2020A+ Class T AmpI bought this little amp a couple weeks ago to improve the sound of music coming out of my laptop. I used this with a pair of older bookshelf speakers. The set up sounds terrific. Amp has way more volume available than I will ever need. No "muddy" sound...... everything is crisp and distinct. Box came VERY carefully packed. My brother has been doing business with these guys for years; this was my first time. But hey, with products like this, free shipping, and a very liberal return policy..... what's not to like?

Rated 5 out of 5 by from Compact design and perfect for my 19 inch TV.Have been using this amp for a couple of weeks now to power two 3 inch midrange speakers circumventing the TERRIBLE speakers in my 19 inch TV. Could not be more satisfied.

Rated 5 out of 5 by from great valueI use the amp in my office at a university. So I really can't crank up the volume without disturbing others. I'm using BIC indoor/outdoor speakers with it. The amp does everything I wanted it to. So if you don't want to play music loud, this is great value.

Rated 5 out of 5 by from Nice little amp!I was skeptical of this little unit, but based on reviews I gave it a try. I can now say I am very happy I did. The output of the unit is surprising. I am a little hard of hearing so my wife banishes me out to the garage when I want to jam a little. This unit was used to replace my 100W Kenwood surround amp that died on me a few months back. I won't say it shakes the walls like the Kenwood did, but for the price It can't be beat.

Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply

What power supply is this amp currently shipping with? Is it a 12VDC 2A...? Or are they now shipping with a higher amp rating PSU? Thank you!

Asked by: tylerdurden

How can I hook this amp up to a battery for a portable application 

Asked by: Travis51
You can use either the (335-370) 2.1mm adapter or the (090-489) 2.1mm cable and connect it to a 12vdc battery.

I have mono ceiling speakers, can I get mono output from the amp? Can I hook speaker leads to one channel , then bridge + outputs with a wire?

Asked by: Steverino
Unfortunately this amplifier is not bridgeable. All you will be able to do is use either the left or right outputs, they cannot be combined.

Hi Guys, love the amp, but is the blue light around the volume control supposed to flicker?   Loose connection perhaps, or is there a replacement bulb? thanks, PJ7

Asked by: pacojoe7
