Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply
Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply is rated 4.4301 out of 5 by 272.
Rated 5 out of 5 by from Great Lil ampThis is an excellent product for the price, I bought to use with the MTX 5i bookshelf speakers and am EXTREMELY PLEASED. It is plenty loud for a small room and the bass and treble controls work fine.

Rated 5 out of 5 by from Great soundI installed this behind an outdoor TV, under a covered deck, customer had installed speakers in ceiling but had no idea how drive them. Took TV out into amp, what a sound. 1/8 inch jack taken by teens for tunes by the pool. Great sound at a great price.

Rated 5 out of 5 by from great ampBought for the garage system. This little amp rocks. Pair this with some nice bookshelf speakers and you will not be disappointed. Will buy another for the upstairs MAC.

Rated 5 out of 5 by from WOWI have this plugged into my two 12" fisher towers and I use my phone to play music.Unbelievable the sound that comes out of that little 20 watt amp.

Rated 2 out of 5 by from Sounds great at low volume then huge distortionAfter reading reviews for this amp I was excited to get one, bought 8 actually.They really do sound great until the distortion hits. Anything over 1/2way on the volume knob and it sounds like absolute garbage. Not even close to listenable.I'd say you're getting 6-10w/channel before the distortion makes it unusable.Why even bother allowing the knob to go that high? Rate it at 10 amps with no distortion and everyone would be happy.Certainly will not buy another.Yes all 8 sound identical and distort at the same spot, tested with many power supplies, speakers, even a 12vdc battery.

Rated 5 out of 5 by from This little amp exceeded my expectations.I bought this amp to power a pair of the Dayton CS620C 6-1/2" 2-way ceiling speakers. These speakers can handle 35w rms and I was expecting to maybe be able to listen to them at a low volume, but they can go fairly loud before distortion really begins to set in. More than sufficient for the bathroom in which the speakers are mounted. I'm quite impressed considering the small size and price of this amp. I'm using a 12v 5a power supply, maybe that helps.

I am having issues with my phone freezing when plugged in and listening to music. My boyfriends phone does the same thing. We've double checked wiring and everything looks good but we can't solve this problem.

Can you hook up a turntable to play vinyl lps, to this amp?

Asked by: Radican
Yes, however if the turntable has only a phono output, you will need a phono preamp in order to get the full output from the turntable.

I'm using this in a portable hi-fi system and have a 12v-17mAh jump starter battery that will power it. Can I mount a size M DC power jack to the back to have the option of running it off 110v with the supplied adapter without disconnecting the battery?

Asked by: DangerDad828
If I understand correctly, you are wanting to have both the adapter and battery plugged in at the same time even if only one is being used, correct? Unfortunately this is not recommended since the power adapter is not a charging device and could damage the battery.

Would like to mount under a cabinet. Can I unscrew the end panels, slide the board out and re-install it so that the mounting feet are facing up instead of down? I have seen pics of PC Board only tests on this so obviously it can be removed.

Asked by: Stevedrivr
There is a good chance this will be possible, although I cannot verify it without disassembling a stock item. If the amp board is seated into grooves inside the case, it may not be possible to flip the innards 180 degrees.

How many ohms it can handle? Can this bad boy run 2 ohms drivers? Will this work with 2 tang band subs (6-1/2; 4ohms) wired in parallel and two faitalpro 3" full range drivers (parallel 2 omhs total)? Thanks

Asked by: inTime
Lepai recommends no less than a 4 ohm load on this amplifier.

This is a very specific question. I have a cheap stand alone dvd/cd player with no preamp built in. Under normal circumstances I would need to play it thru a tv or my integrated amplifier to hear anything. Do I need a preamp with this unit?

Asked by: BillyBoy
No you do not need a preamp with this amplifier. Any device with line level output can plug directly into it.
