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 4.4343 out of 5 by 274.
Rated 5 out of 5 by from amp reviewgreat looking amp. Works great with t.v.in spare bedroom making volume loud enough to hear over exercise equipment.

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.

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.

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

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.

I have a New Samsung digital smart TV  , can I use this to connect to 4 ceiling speakers. Has any one tried it?  I don't want anything chunky or expensive, will this amp do the trick?

Asked by: Basile
This amp will work as long as your TV has red and white analog outputs. If it only has digital outputs you will need a digital to analog converter between the TV and amplifier.
