4.0 out of 5 stars A Good Mini Amp for Bookshelf Speakers Sept. 16 2013
By VRadha TOP 1000 REVIEWER
Verified Purchase
I hooked up this mini amp to two satellite speakers (Energy Take Classic). The input was either from a karaoke machine or from a wireless microphone. Also tested with output from my laptop. The sound is amazingly great for a mini amp. The MP3 (3.5 mm stereo) input is very convenient to hook up laptops or other portable audio devices. The Direct/Tone control is also very useful (though I use the Direct mode predominantly). The blue LED lighting around the volume control knob is pleasing to the eyes. Overall, I am happy with the purchase.

5.0 out of 5 stars Great, especially for the price Nov. 25 2013
By Andy TOP 500 REVIEWER
Verified Purchase
I'm driving a pair of Sony SS-B3000s with this little amp and I'm very happy with the results. Tests around the internet show that the amp maintains very good levels of harmonic distortion up to about the 5-10 watt per channel range (this improves quite a bit with 4 ohm speakers), so don't expect high fidelity with this thing cranked. But for home listening at relatively low power, it's sounds fantastic. And for $20, you can't knock it. The bass is solid, treble is clear, mids are strong.

On a side note, when talking about sound, 5-10 watts is quite a lot. Perceived volume is a logarithmic function of power. Almost no home system had over 10 watts of usable volume until the 80s and it often came along with a loss of fidelity at lower volumes. Especially when it got ridiculous in the 90s with 500 watt home systems. The funny thing was that people still didn't use more than about 5 watts, even with their music "loud". And most home systems still sound terrible at full volume.

I'd put this up against most home receivers from the 90s in a heartbeat for fidelity in the first 7 or 8 watts, which is all I ever use. It's just unbelievable for its price and size.

5.0 out of 5 stars Good value for money Dec 11 2013
Verified Purchase
I've had the Lepai 20W stereo amp for a few weeks. I'm using it with the provided power adaptor (110V mains to 12V @ 2A) which is a small, light SMPS unit that plugs into the wall. You also have the option to connect a 12V battery power supply if you want something portable for travelling, camping, picnics, a busking amp, etc. A rechargeable 12 sealed lead acid (SLA) battery (burglar alarm/emergency lighting battery) would be ideal but remember that you can't take SLA batteries on planes or through security checks.

I have it plugged into a pair of small, low quality bookshelf loudspeakers so I can't really comment on the sound quality. The tone controls (bass and treble) make a noticeable difference and I think have a sufficient range for what you'd expect from a small cheap amp, plus there's a bypass switch. The case and controls have solid construction and I think the unit would survive a few knocks and drops - important if you intend to travel with it or use it for busking. I haven't tested it but I expect the 2A power supply is easily enough to get a full 20W out of the amp without distortion or losing bass response, however, that doesn't mean it wouldn't overheat if played at full volume for long periods of time. It's easily serviceable but, for the price, it's probably cheaper and easier to buy a new one if anything goes wrong with it.

Overall, I'd say it's a bargain at the price, robust and flexible, a decent quality... ...and no, I wasn't paid to write this review! I genuinely like it.

The quality of the LP-2020A+ is surprisingly good. I hooked it up to a pair of good bookshelf speakers and it works well from my iphone itunes at 192kbps over the analogue wire. Is it as good as a 500$ or 2000$ amp ? less full, so no. Is it well worth the price and surpasses most peoples' needs ? yes, i was surprised at the sound. Is it loud ? loud enough to cover a few rooms at moderate intensity. A good purchase for my needs which was to drive a few very good speakers with fairly reasonable quality with a very low cost, small size (it's super light too), and with good enough quality.

It's small, incredibly easy to hookup, and the sound quality is perfect.
I've four small speakers installed in my cafe and this mini amp takes the sound from my iPhone and distributes it seamlessly.

Price is amazing as well!

The product works well for it's price, However, at loud volumes it has a humming noise, so just make sure you don't turn it up too much.

5.0 out of 5 stars Excellent for powering spare speakers May 12 2013
Verified Purchase
Great little amp for powering any spare speakers you have laying around. Doesn't get hot after hours of use. It also has a speaker protection circuit so that when turning the power switch, there is no loud pop only a tiny click.

5.0 out of 5 stars Phenomenal! Jan. 18 2014
By moose TOP 500 REVIEWER
Verified Purchase
I had some high quality bookshelf speakers that couldn't be used due to a malfunctioning amplifier. I purchased this unit based on others positive reviews and am now writing my positive review! This unit is actually much smaller than it looks in the picture. My speakers perform just as they did when hooked up to my old, top of the line amp.

The blue light is a bit too bright, I wish it could be turned off. I've used some electrical tape to cover it as I use the speakers in a bedroom.

I don't use the equalizer settings and leave the unit on direct mode. It's hooked up to a wireless receiver making the system pretty sweet for the price!

Would recommend.
