Lepy LP-2020A Hi-Fi Digital Amplifier, Mini Stereo Audio Amplifier with Power Supply Black US

This is the same unit as others on Amazon under the model number Lepy/Lepai 2020A T-class amp. This seller just sells it for cheaper.The box was surprisingly well packed, using soft foam material instead of styrofoam. It's easy to pack it up again and transport it if needed.The sound quality is VERY VERY good, considering this price point. This is the 3rd of these small T-class amps I've purchased, and I'll compare each of them.-First one is Topping TP32EX with TK2050 amp, rated for 50W but at 10% THD+N at 4ohm. I wrote a thorough review of that product, and found the maximum usable power is only about 10W per channel at 8ohm before it starts to distort too much. The TP32EX is 7 TIMES more expensive, but the sound quality is excellent and the USB DAC + Headphone Amp all in one device serves a different purpose than this Lepy.-Second one I tried and immediately returned is Pyle PFA400U 100W with who knows what T-class amp it has (they don't want to list it). I wrote a thorough review of that as well. It has HORRIBLE sound quality, completely unusable due to the distortion of mid bass starting at 20% volume. I didn't know how bad an amp can sound until I heard the Pyle of crap.This Lepy is the 3rd unit I purchased, which will be used at the office to drive a small pair of bookshelves. I tested the amp with Elac B6, Polk RTi-4, and an old Infinity US-1 Satellite speakers for the heck of it. The sound quality is worlds apart compared to the Pyle, and I was pleasantly surprised to find out there's little to no distortion even at maximum volume. It actually gets louder than the TP32EX even though that unit is marketed as higher power. They sound very different, however. Testing with both the B6 and RTi-4, the Lepy sounded warmer and bass was over pronounced compared to the TP32EX. The TP32EX in comparison sounded much tamer, and especially the details of mids on the B6 were present. At higher volumes with the B6 (which are known to be pretty flat speakers), the TP32EX maintained the balance well and nothing was overpowering. On this Lepy however, the boomy bass took over past 50% volume and started sounding muddy it became harder to focus on the details of the highs.In the end, I would hands down recommend this unit. For the price, especially from this seller, it's a great deal. It's the cheapest TA2020A based amp that I could find on Amazon, and I'm glad I picked this up. With the RTi-4s, which only has a 5.25" drivers, the bass was not as overpowering and it was pleasant to listen to at 50-75% volume. At lower volume, it sounded a little better than the TP32EX which was a bit hollow on the RTi-4.We'll see how long any of these Chinese made units last, but the Lepy did not even get warm when listening to at normal volumes (as loud as you'd want in an office). And I'm sure it will work in a pinch at the next office party, if you needed it to go louder.

This thing drives my speakers very well and it cooperates with the signal from my pc perfectly.TLDR; It's wonderfulI manually adjust my systems equalizer as the preset ones always sound bad to me, save "flat" which essentially does nothing anyway.I found it strange that the power supply it came with was a 13.5 volt @ 3amp model while the picture showed a 12 volt model.I also find it strange that when you switch it on it makes a click noise that sounds like the over-power protection is automatically tripped. But i guess it's a "device on" click.Which build is it?Just to quickly bring up internals, there's no heatsink on his model or at least, no heat sink on mine. I've seen on forums (whilst researching) that some have heatsinks and others do not. What this says to the overall quality i'm not sure but as of today this unit is working for me fantastically. Also yes, i am aware that this is the "Non +" model.I'm using it to drive two sets of speakers which i have wired together with custom high and low band pass filters.I've put the tweeters in series, one is 4 ohms the other is 6. The same goes for the mids.Assuming i understand the math, at the end of all my wiring, each channel of my amp is doing 5ohms of work i.e. 10 to the tweeters, 10 to the mids and since they are paralleled into the amp it should be 5 ohms.I haven't had any distortion, popping, or crackling during normal volumes with my test suite of songs. "Normal" here means from lounge levels to loud enough to bother the neighbours.If you're curious, my test suite is as follows:Sweden Rhythm - Two Fingers: to test bass. shook the room.Symphony No.7 in a major OP 92 part 2 - Beethoven: to hear all those subtleties and vast swings of musical intensity.Easy Muffin - Amon Tobin a complex song with multiple sounds from the fore to the background going on at the same time, nothing was lostThe Lighthouse - Amon Tobin another complex trackThen some Mick Gordon, Brendon Small, MF DOOM, Prince, Nightwish and Rawtekk to test aggro tracks and vocals. I heard everything i expected to hear and nothing was lost.EQ settings for Pulse Audio:Music through spotify i don't turn on my EQ for."System Wide": This is an aggro setting50Hz - 5.9, 100Hz - 4.9, 156Hz - 6.3, 220Hz - 6.3, 311Hz - 2.3, 440Hz - 5.3, 622Hz - 3.0, 880Hz - -4.0, 1.25KHz - -1.3, 1.75KHz - 1.6, 2.5KHz - 3.6, 3.5KHz - -1.3, 5KHz - 3.3, 10KHz - 6.3, 20KHz - 5.9"Standing Speakers": This is a setting for media that's pushing way too much bass for it's own good or where I don't want bass.50Hz - 0.8, 100Hz - 0.2, 156Hz - -0.5, 220Hz - 0.5, 311Hz - 2.8, 440Hz - 4.1, 622Hz - 4.1, 880Hz - 6.8, 1.25KHz - 6.5, 1.75KHz - 5.1, 2.5KHz - 3.8, 3.5KHz - 5.8, 5KHz - 4.1, 10KHz - 4.8, 20KHz - 5.5

After reading many of the other reviews I decided to get it a try and was very happy with the results.I had inherited a set of Sony tower speakers and had been running them with an old sony stereo unit that had no audio inputs other than an iPod connector. This used to be fine but since I made the switch away from apple products it left me without a way to use my speakers. With this little guy bolted onto the back of the speakers and plugged into my XBMC-pi I can not only listen to all the music on my network but also use them for movies too!The Good:It has a very small foot print, at less than half volume the sound is fantastic, the blue lit volume knob helps to remind me its on, has low energy consumption, can manually adjust highs and lows, has both 3.5mm & RCA inputs.The Bad:The blue light can be a bit distracting if it shines directly at you, the power supply is huge and has a short cord, above half volume (as others have mentioned) the sound becomes somewhat flat, the manual audio adjustments are a bit limited.Conclusion:For the money this little guy was a great buy and I don't regret the purchase one bit. I am planning on purchasing its bigger brother now to take its place, and use this one to power some smaller Sony "bookshelf" speakers. I would recommend this to anyone in need of an amp for powering good quality speakers without the use of a component stereo receiver.
