Lepai LP-2020TI Hi-Fi Mini Class D Stereo Amplifier - 20W Max at 4 Ohms, 12W Max at 8 Ohms, Digital Audio Solution with Power Supply

Before picking up a couple of these little amps, I read up on the amp-classification issue and Lepy vs Lepai branding. This seller is right on top of the chatter, marketing the TI circuitry and such. It's been years since I paid close enough attention to audiophile issues, but I felt comfortable enough with the new product to order a couple. Right now I'm listening to one driving Polk Audio bookshelf speakers which I have running as background "infill" for a whole-house system running Chromecast Audio. And I'll be darned if I notice a substantial difference in sound quality in comparison with far more expensive receivers & speakers on other zones. At this price point, I have to call it a miracle. After I've given these neat little devices more of a workout, I'll come back and bump them up to five stars. If the miracle holds out. (Edit: Two months later, I now own three of these and have given two more as gifts. I also own Accuphase and McIntosh gear and though it's apostasy to say so, this one gives more bang for your buck. So: 5 Stars.) Update: A week later, so far so good. Have two of them hooked up and they never even get warm and I have cranked them a bit. Sound is still reasonably clean which is amazing at the price point. There can be a touch of shrillness in the upper midrange but since I'm usually listening to Pandora the source material can be the issue. One note: when you switch them off, there's an unpleasant transient pop delivered to your speakers--not loud enough to blow anything, but annoying nonetheless. Not enough to cut a star from the rating anyway. PS: Please note that I have made reference multiple times to this item's price. It's because that's the context within which I can refer to these amps as 'small miracles'. They're certainly not going to outperform a $1500 amp, but they'll definitely give your average $100-150 amp a run for their money. BTW, on both of my units, the bass and treble controls (as well as the balance control for that matter) work fine. HTH!

I am no audio expert but I am perfectly happy with this amplifier. I am using it at less than half volume which is perfectly adequate. I don't have great quality speakers but the sound I am getting is as pleasant, clear and as pure as I was looking for and I am more than satisfied with the quality I am getting. Really, for this low, low price most ordinary non audiophile folks like me couldn't go wrong. The blue glow around the volume control is a little bright but I hardly ever notice it when I am looking at my two monitors. The sudden "boing/popping" sound when the unit is turned off is a little unsettling at first but why should one fuss about that, this is a very minor point to be concerned about in such a delightfully efficient product that does everything it is expected to do. Only true audiophiles should keep looking around and checking the minutest details when looking for an amplifier, the rest of us should just sit back and enjoy this product for what it is, perfectly capable and heck.....very cheaply priced.

It is an OK amplifier, not ultra high quality, but what do you expect for $30. Actually, it is a pretty good deal for a mid-fi system. If you are on a really tight budget, then this . amplifier and a pair of monoprice, and/or Dayton audio $60. Speakers is a fair deal. It says that it will take a 4ohm load, but when I paralleled 2, 8 ohm speakers on heavy bass music, it shut down to protect itself. (They are safe for anything down to about 6 ohms I guess.). If you need two pairs I guess you will have to wire them in series, (which I hate to do.). Overall, if you want a cheep system that has reasonable quality then this amplifier will do well in a pinch. UPDATE- As I used this amplifier for a few months, I discovered that, for it’s price point it is quite good. I am using it to push a pair of Monoprice 6.5 speakers. I use them for deck top use and they are adequate for casual use. It is definitely not an audiophile quality, but it gets the job done. All in all, an excellent choice for a budget system. P. S. When I said it could not push a 4 ohm load, I found out that the two pairs of speaker were both 6 ohms nominal, ( which means that they may dip down to 4 ohms, or even less, in spots, so the amplifier is indeed,, 4 ohms stable. ) so, for the money, it is a pretty good deal, for a modest sound system.

*I bought this peticular amp to use in a boat/rv enviroment where 120 isn't always available, but 12v DC is. I havn't even hooked it up to a battery to see how it works in that aplication, but that's the reason I got this one.* The amp its' self seems to work really well, it drives a pair of name brand compact bookshelf speakers to a decent volume. They're a little light weight, and rated to the same wattage as the output. The bass control will cause clipping if it and the volume are turned up too far together. I havn't tried another pair of speakers to determine if it's the amp or the speakers, but listenability is good, and I usually have plenty of extra volume for casual listening. The BAD: There's no ballance control....nuff said about that. Worse: The power supply is a switching type (google it if you want to know more...it's way easier than me explaining it)...and it has almost no filtering on it, so it's really noisy, and almost useless if you want to play a radio through it unless you put some snap on ferrite beads on the imput lines. A decent power supply wouldn't cost that much more. I didn't have any issue playing other sources. All in all I'd recomend this for playing mp3s etc. as an alternitive to a bluetooth speaker.

I have purchased two of these amplifiers. The first I actually used in a vehicle, running off of the cigarette port and it worked great. However, it died due to dropping and excessive sunlight. I ended up moving my speakers indoors, and purchased a new unit, and it works exceptionally well. The only functionality missing is a "Pan" knob, but that is more of a want than need. It has inputs for either a computer (Red and White cable) or a telephone (AUX Cord). Very simple to set up, can amp louder than my speakers can handle, but can be quiet enough to use for normal listening. Overall amazing product, will buy again if I ever need to (which is not likely as the construction of the product is great).

I just need a simple audio amp to relay phone ring & text msg notification sounds through an additional BT adapter. This works for my application because my house is pretty large, there were times when I had no idea I've been getting calls and messages. The audio is excellent, about the same as most modern flat screen built in amplifier. It's on par with most LG, Samsung, & Sony LED TV internal amp which are the best , Vizio is second tier, Westingouse is the lowest. True it can get louder but the audio becomes distorted past 12 o'clock. You'll also get no humming noises at max but audio is distorted. I can't really give this product 5 stars overall, here are my issues. The power adapter received is god awful. It made this unit putting annoying loud mid-range pulses that is simply wayyyyyy too loud. Adapter ain't cheap and it'll tax more to the overall cost of ownership. Second, the RCA connector is garbage. It works now but I don't doubt this last long. The audio chip has no heatsink attached which might explain the distortion. Once the vol is past 12 O'clock, I noticed the power consumption jumped to 10W. Adding a heatsink will also tax more the cost of ownership. And last issue is the audio connection isn't high quality, I preferred banana plug receptacles. For my application it's no biggie, with nothing playing this unit uses only 2W!!!!! It goes up in variation whenever it receives a tone to output. Which means I can have it running 24x7, never having to turn it off since all I'm doing is using it to make ding dong sound to let me know hey I'm getting calls, need to respond. That's my main requirement so I don't break the bank on utility bills. My other requirement is bass/treble control. This has has it. Just keep in mind you'll need to glue on a heatsink to the TI chip ($10) if you're going to play music through it. That's optional, and required to spend another $15 on good 19V or 24V / 3A+ power adapter. Even if I had received a working adapter, I won't recommend using it either, you'll need to a full 24V swing adapter, not 12V, it won't put out enough power. In the end you're looking at about spending $50 total, crap you might as a well looking for the $50 unit that does more, I've even seen unit that comes with low ESR Nichicon caps for $50. Definitely looking for the same chip though, this is an excellent audio chip. Just don't expect it to out perform $150+ home theater receiver lol be realistic. This unit still make hella lot of noises for an avg human consumption but not enough to get your neighbor to call the noise bolizes

First of all, I'm sorry that nearly 25% of purchasers could only give this product one star. My experience is based on a whole year of listening with a variety of modestly priced bookshelf speakers from a variety of makers. This amp has way exceeded my expectations, being driven by a cheap Philips universal player and my Kindle Fire tablet. I am very pleased with the sound quality and that it can produce lots of volume without distortion. For those considering a purchase I would suggest the buyer protection plan at a really low cost, and this would ease any fears of failure. I have had no problems in a whole year of use. I also note that a year ago I only paid $25 for the Lepai. Some times I just sit in amazement at the sound that comes out of such a small device. I have assembled a budget system over the years that would retail for about $4000. If it disappeared and all I had was the Lepai I would not feel terribly deprived. I hope this review is helpful.

I moved into a house with existing speakers mounted to the wall of a porch. I was curious if they were any good, and if they needed replacing I’d need an amp anyway. This little guy fit the bill and the price point was great for the fit and finish. The bass and treble knobs seemed to have an odd range for adjustment, like maxed out sounded like where the mid should be, but perhaps that was some character of the found speakers. Anyway, I got it balanced out and it reproduces sound accurately. I paired this with an Echo Input, which I now use as a patio music server, and I use the Echo device to control volume. Just tell Echo to play at “10” then turn the amp knobs to the loudest you plan to listen to. Then tell Echo to back off to maybe a “volume 6” and enjoy. Later I added a headphone splitter from the Echo Input and fed that to an old Klipsch sub I had laying around. The resulting diminished output isn’t enough to wale the sub when in idle mode, but the amp handles is fine. To have the sub present without having to hit a switch on the back or leaving it on all the time, I tied the sub and this amp to an exterior smart switch. Then I hid all wires, amp, and sub in an exterior Suncast box with holes for the sub to breathe. Now I say “turn on porch” and I hear the light speaker pop indicating the amp is running and ready to jam. For reference, I’m a bit if an audiophile. I built Zaph audio BAMTM as my mains and C-notes as my surrounds for 7.1 theater. Currently running a Klipsch 12” down firing, but working on building two “full Marty” subs with 18” Ultimax. I also used to be a musician, and even played at the North Sea Jazz Fest. I just see a lot of reviews loving and hating and was curious of their background, so here’s a bit of mine. PS: I hate Bose!
