Lepai LP-2020A is an essential upgrade to turn your vinyl music into HiFi quality. Whether you are a budding enthusiastic or audiophile, you can’t go wrong with this 25 dollar (USD) mini amplifier.
At just 11.5cm wide by 4cm high by 9cm deep and 300 grams, the output of this amplifier is amazing. It offers 20 watts per channel continuous output, two inputs (RCA & 3.5mm jack), and bass and treble controls. We use it to drive 6 1/2 inch two way bookshelf speakers and Lepai does it with ease.
The core of the amplifier that does all the magic is the Tripath TA2020 amp chip. It was cited by the engineering magazine IEEE Spectrum as one of the chips that “shook the world” when it was introduced in 1998. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
There are many mini amplifiers in the market nowadays which incorporate this amp chip. You can cross check the pricing with Topping TP20-MK2 TA2020 Class T Digital Mini Amplifier, which is around SGD140. Both amps use the same TA2020 chip anyway. That’s why I feel that the Lepai beats them hands down due to the ultra cheap price and equally astonishing performance.
Selling Price: SGD 70.
- There are many versions of this amp. Ours is the latest 2012 model with tone balance control, built-in protection circuit, and 12VDC power supply
