Amplifiers Reviewed
| Amp | TL;DR | Teardown & Testing |
|---|---|---|
| Lepy LP-2051 | Driven by the Tripath TK2051 as opposed to the more common TA2020-020, this is the most powerful of the bunch. If you’re looking for clean power and don’t mind the 19V power supply, it’ll be hard to find a better value for your ~$40. |  |
| Lepai LP-2020TI | This is the one Parts-Express claims is the true successor to the Lepai LP-2020A+. Powered by the TI TPA3118. The power handling is good, but magical presence the Tripath brings just isn’t there with the TI heart. | |
| Kinter K2020A+ | In my opinion, this is the true successor to the Lepai LP-2020A+. It sounds slightly better than even the original. Powered by the Tripath TA2020-020. At ~$40, it’s a bit steep, but probably still worth the cost if you’re looking for a 12V Tripath. | |
| Lepy LP-2024A+ | Considering the model number, I expected this one would have a Tripath TA2024, but it turns to have a TAA2008. Objective performance just barely beats the Lepai LP-2020A+, but it doesn’t really matter since neither one is on the market anymore. | |
| Lepai LP-2020A+ | The mini-amp that started the craze. Great sound at a great price, but you simply can’t find them anymore. Powered by the legendary Tripath TA2020-020. | |
| Lepy LP-2020A | Powered by the Yamaha YDA138, this one falls short on magic. With some component replacement it’s potentially possible for this to be an quality amp, but as-shipped, steer clear. | |
| Lvpin LP-2020A+ | So far as I can tell, this is an exact copy of the Lepai LP-2020A+. It sounds identical to my ears. Powered by the legendary Tripath TA2020-020. At ~$10, you can’t really go wrong. Buy two and wear them like shoes. | |
| Pyle PFA200 | Pretty similar to the Lepy LP-2020A above. Unknown amp chips with obscured labeling. Doesn’t feel like “Class-T” as the marketing wank claims. | |
| Lepy LP-V3S | Supposedly based around the Toshiba TA8254, I’m expecting this to be pretty similar to the Lepy LP-2020A. Ordered in May 2018 – Full review coming soon. | |
