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.

As of this writing, the unit I ordered from Amazon has not arrived yet, but I already have a couple of these so I can safely give my review of it. If you're considering one of these, this is the one you want. It's worth the extra three bucks for the improved start up circuitry. The older unit will give a loud pop through your speakers when you turn it on. With good speakers, these things are amazing. Keep in mind that we're talking about a $20 amp here. It's pretty well documented that the power supply that comes with these is inadequate at best. Out of two that I purchased elsewhere, not at Amazon, one had a bad power supply. If you get a power supply that works, the amperage is too low to get the most out of this amp anyway. I am running two of them off of a old computer PSU, which is rated at 12v 24 amps. There are many suitable power supplies on Amazon that sell for about six bucks. The Lepai amp itself is very light weight, does not feel like a quality piece of hardware in your hand. The sound is great, depending on your speakers. I use one with a pair of old Bose 501's (purchased in '78) and another one is paired to some Dayton B652 bookshelf speakers. Both sound pretty darn good with these amps. This third amp will see service in the garage, and in the driveway when I open the garage door. These amps are capable of much greater volume than you will ever need. They will sound better if you do not crank it all the way up. At half volume, these things are very loud. They run very cool, even after several hours of constant use. I started using these amps when my Yamaha receiver (15 years old) started to have a problem with arcing. I'm not in a position to shell out a couple grand for a new one at the moment. I am pretty happy with these cheap amps for the time being.

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.
