| The Topping TP 21 is a so-called Class T integrated amplifier, based on the TA 2021 chipset. the chip makes use of a kind of Digital Power Processing, this is, more or less, a Class D amplifier with high rate switching properties. That is why they put the word digital into it. Actually, there's nothing really digital inside, not in terms of D/A conversion. You can view the official TA2021 datasheet, with detailed tech specs, The Topping TP 21 is nothing else than a pure and simple application suggested by the chipset datasheet. No magic.Build in Op amp for headphone liner boost, easy to drive any headphone in 16 Ohm to 200 Ohm impedance loading,the speaker cut off automatic when the earphone jack plug in.Totally 7100uF super large capacity with ELNA Pioneer Audiophile Grade Cap, very low ESR and high speed response sounds much clearly in detail and huge in deep bass.High grade component in use, there are Dale resistor, ELNA Caps, ALPS volume control, gold coat PCB,pure copper RCA socket with gold coat.It will be amazed when drive to high sensitive (more than 86dB) speaker! You can't believe your eye but really hear the great sound from this little T amp! |
