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 4.4311 out of 5 by 283.
Rated 2 out of 5 by from Clips easily with BassI bought this for a pair of Polk's R15s I had sitting around. Thought it would make a great desktop PC speaker system. Its OK until you want to raise the volume over half way with some added bass. Then the little amp seems to quickly degrade and clip, even cutting out on heavy bass. The Polks can use as little as 20 watts and as I said, low to middle volume the little amp can do OK. But don't think it can run much in the way of speakers other then small bookshelf ones. This leaves the abilities of the Tapai 2020 a bit handicapped. My feeling is this amp is more in the 10 to 15 watt realistic output and not 20. Even though its cheap, I would opt for something more just to be able to run bigger speakers at higher volumes.

Rated 5 out of 5 by from Exactly what I was looking forInstalled this amplifier (and four SAT-BK speakers) as the music system in a small coffee shop. Just needed an amplifier, but I must say, having the tone controls is an added bonus. The coffee shop owner is extremely happy with his new inexpensive "surround" setup!

Rated 5 out of 5 by from Great Little AmpThis is my third LP-2020A+. I keep finding more applications.

Rated 5 out of 5 by from Perfect!I bought this because my reciever went out, and I thought it might not be enough to give me loud sound in the two dayton audio in-ceiling speakers I just installed, but it absolutely rocks! I am about to purchase two or three more for other rooms in the house.

Rated 5 out of 5 by from Use it as intended and you'll love it.I bought two of these recently, I had some Polk T15 bookshelves sitting around that used to serve as surrounds in my living room, the wife made me switch to smaller satellites. I set out to find a product to power them in other applications around the house and landed on the Lepai.In the near-field desktop situation, the sound is remarkably clear. There's actually more definition to the bass and more separation in the instruments than I had from these same speakers on my 125x7 sony HT amp. The volume is surprising with the T15's. I think that paired with a small powered sub with speaker-level inputs, a polk psw108 or similiar, it would make a very passable setup for small-room HT or stereo listening. Without a sub, the bass is detailed, there's just only so deep the amp can go with a 5.25" woofer. These speakers can get loud enough with this amp to make me uncomfortable sitting in front of them and disturb people in adjacent rooms before clipping sets in.In the garage environment (sheetrock box with a polished concrete floor) the speakers get a fair amount more room gain. The sound isn't as clear but it is impressively loud, certainly enough to annoy my neighbors if they're using they're yard, though not enough to carry into their house. Certainly it works for the purpose of playing my music and audiobooks while I work on the Jeep. It would need a more efficient speaker and a powered sub to really fill a large shop though I think.As some of the other reviews mention, this amp really doesn't seem to be up to 20Wx2 rms, based on some measurements I took it really seems to do more like 10-12x2 rms. I wonder if the specs are mistaken, the amp actually has "20W RMS" printed on it, not "20W Stereo" or "20Wx2". If they're claiming 20W rms total then they're dead on or even a bit conservative.Oh: Final note, mine have an on/off pop, though not a severe one. I think I have the 2020A though, not the 2020A+, I believe the "+" indicates an updated circuit to remove the pop using a relay.

Rated 4 out of 5 by from Loud and cleanPurchased this along with a pair of fullrange drivers to construct a simple bedroom sound system for my son. Unit is amazingly light and produces clean audio with surprising tonality. Simply outstanding for such a low price. Highly recommended.

Can the analog out of a dish sat. receiver be used to feed into the amp? If so could each sat. out be split to feed both TV and amp without any problems?

Asked by: Wal792
Yes the analog output can drive this, splitting the output should not effect anything negatively.
