Rated 5 out of 5 by from Great amp!Have two of these for outside dining-room speakers. Great performance for the price.

Rated 5 out of 5 by from Not bad...not bad at allBought this and a pair of Dayton Audio 61/2" speakers to replace my old PC speaker system.My old set (semi high price PC speakers) has the amplifier built into the left channel. Had them for a couple years until the left channel refused to play anything unless the balance was set so high to that speaker that they sounded like absolute garbage.So, after a lot of looking around, reviews, etc. I decided to get this amp and a set of regular old speakers. I'm so glad I did.This with the speakers sound amazing . Going from 3" to 6 1/2 " speakers, I know, is a huge difference, but this combination sounds so crisp compared to my old ones. No noticeable distortion when I decide to crank it. I only have the amp at half volume and it's more than enough for my listening needs. Don't wanna tick off the neighbors too much haha.The blue LED is a nice touch, matches my computer's light scheme.My only complaint is that the power adapter included has to have the shortest cable I have ever seen on AC power adapter. Must be what, 3 feet? It BARELY reaches down to my power strip. It also is one of lightest 12V 3A adapter I have ever felt, so I feel that it's probably going to cook itself like another lightweight AC adapter I had. I'll have to replace it eventually...any recommendations?Lovely little amp though, I should of done this years ago.

Rated 5 out of 5 by from Mighty!I purchased the upgraded version from this when Lepai changed their name to Lepy but very much the exact same. Very high quality knobs, smooth rotation, bass and treble bypass button "Keep it on eq" two methods of input, 1/8" headphone and RCA, as tiny this amp is, it's very practical and for 20 watts, it's mighty. It's powering my Cerwin Vega L-7 speakers and it's loud and very crisp and clean bass. I'd recommend this to anybody.

Rated 1 out of 5 by from Not ImpressedScratchy volume knob. Loud popping in speakers when touching volume knob. At 31 days it became un usable. Removed case to find poor solder joints. Not sure I even want to try a different brand T-AMP at this point.

Rated 4 out of 5 by from Good Sound, Clean and priced rightNice clean amplifier. Good looking. Seems to be dependable. I've enjoyed mine now for more than a year in a rough environment with no problems. The only disappointment was the tone controls. It adds so much noise into the amp it should be left out of the circuit. Other than that it's a very good value.

Rated 4 out of 5 by from RawI've owned this amp for about 2yrs. That should say it all $20 bucks 2yrs of service and its still works like a champ volume nob a little noisy, but you can't complain about that. Real value. I own the Dayton DTA-1, DTA-100, and of course the Lepai 2020. The DTA-100 sounds the best, really remarkable, very musical refined just love it. The DTA-1 not bad bust just not enough volume for the moments where you need just a little more volume. The Lepai has a little extra volume you need but, very raw no refinement for my taste. Not a bad amp by any means just a bit on the raw side lacks texture and smoothness. It's your go to garage amp gets the job done been reliable but not the kind of amp to listen to for long periods of time. Parts express thanks again for making life a little more fun!

i need a replacement amp chip for my 2020 how do I get one?

I need a power plug that will fit in a cover outside outlet -- the one shown looks like it is more "sideways" -- is that the only one available?

Asked by: spottythecat
We have several options that will work but most will be similar in style. You might consider this "brick" style which might work better for your application.http://www.parts-express.com/sure-electronics-ps-sp11111-12-vdc-3a-ac-power-adapter-with-21-x-55mm-plug--320-312

I upgraded from the 3A power supply this amp came with to a 60W 12V 5A and it made a big difference. Can this amp be improved further by purchasing a 72W 12V 6A or 84W 12V 7A adapter?

I'm an electronics novice and I want to power the Lepai LP 2020A and the Sure AA-AB41136 Bluetooth board in the same portable speaker. Can someone recommend a way to do this with either a rechargeable battery or at the very least a way to combine the powe

Asked by: MrTeeyoprice
Since these are both 12 volt, a simple sealed lead acid battery would work well and is a popular option. Simply split the power from the battery to each device.
