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 4.4332 out of 5 by 277.
Rated 4 out of 5 by from Not an amplifier to be taken seriously.I just bought this amp. It is a Low - Power amp. That being realized, I'm not sure about the 20 watts per channel, both driven at the same time, maybe one channel at 20 watts per side may seem correct. Seems to break up quite easily. Nice package. May be great for small Ipods to sound a little better then what you have. DO NOT expect miracles from this thing.

Rated 5 out of 5 by from nearly indestructableI have been using these amps for over a year and none of the more than a dozen has failed me. I've abused these little gems in ways you cannot imagine. I've short circuited the outputs accidentally, countless times, I've over-driven them and the protection circuit never fails to function, I have listened for a half hour at 100 db plus driving a 2.6 ohm load with barely perceptible distortion at 105 db peaks. They remain cool to the touch even after this abuse. Yes there are better amps but they all cost considerably more; 10 to 100 times more, and even people with little Hi-Fi experience can't damage them without drop-kicking them. They do sound very good under most reasonable loads. I will never be without them. They are perfect for serious testing and most of all critical listening to many different loudspeakers. And best of all they are nearly indestructible

Rated 4 out of 5 by from Good Value for the MoneyWorks Well, Sounds Good. Louder than I predicted it would be. Removed aluminum case and installed directly into speaker box, soldering connections directly to Amp Board for Power, Ground, Audio inputs and outputs.Used with a pair of HiVi BN3 3 ich speakers.http://www.parts-express.com/hivi-b3n-3-aluminum-driver-round-frame--297-428Sound quality Exceeded my expectations.

Rated 5 out of 5 by from How do they do it?I purchased this amplifier along with the Dayton B652 speakers for use as computer monitors when recording/editing audio. I really did not expect much as this amplifier is silly inexpensive. However, I was shocked to hear how clean and clear the audio was. The dynamics felt unrestricted and easy. The frequency response seemed smooth and full. This is my first foray into the world of T-amps and I have to say I am sold!To be clear, I do not run this amplifier at anything past about 10:00 on the dial (since I use them in a near field capacity), so there is zero discernible audio distortion at that level. And I love the fact that they included treble/bass boost/cut controls. With the speakers on my desk and near a back wall, there is some boominess to the bass, however the Lepai amp allows me to cut the bass slightly to remove the boominess and still allow a full sounding bass; very nice!

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.

Lepai LP-2020A+ Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply

I just received my Lepai 2020A+ amp.  (Order #1999688)  I hooked it up to determine that it was working properly before I installed it in a complex physical position (didn't want to take it out again) and discovered that it cut out as I turned it up.

I am considering using this for a small start on a build for golfcart. Should I use a Sealed Lead Acid battery or just use the golf cart's battery? Thanks.

Asked by: Hofe
These are very efficient amps and will not offer much of a load on the golf cart batteries. As long as they are 12 volt this should be perfectly fine.

What is barrel size for power supply? 2.5x5.5

Asked by: adipic9
The DC plug input on this amplifier is 2.1mm x 5.5mm, but a 2.5mm will work most of the time.

How can I power this from my car's 12v outlet?

Asked by: Not Bill
You will need a 2.1mm x 5.5mm DC power cord with a cigarette lighter on the end. We do not have one pre made but you can solder a cigarette lighter to the end of the DC plug wire we have available below.http://www.parts-express.com/21mm-x-55mm-x-112mm-dc-plug-with-6-ft-cord--090-489http://www.parts-express.com/marine-grade-locking-cigarette-lighter-plug-12-vdc--265-272

How do you select the input? I  have both a turntable and my phone connected. Will it decect audio source automatically? Or would I just unplug my phone when I want to use the turntable, and plug back in when I want to use it (leaving the phono alone)

Asked by: ahajnos
Don't use both inputs at once.  Either use the mini jack or the RCA inputs.  I read that these jacks are simply wired in parallel so you will be backfeeding the signal from your phone to your turntable and from your turntable to your phone. Not good. You would need an external selector box to switch between the two sources if you want to leave them plugged in all the time.
