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.

Excelente amplificador, me ha sorprendido la.potencia y calidad
