Ibasso AMP8

Discrete Balanced Amplifier for DX150 / DX200 / DX220

Ibasso AMP8 Amplificateur Symétrique Discret pour DX150 / DX200

The Ibasso AMP8 is an amplifier board that can be combined with the Ibasso DX150 or DX200 DAPs. This amplifier integrates a discrete symmetrical circuit with high voltage and output current. A high output current is very useful, for example, when using low impedance multi-membrane IEMs. For the design of this amplification circuit, low VCE transistors are used and manually sorted and paired to provide transparent and linear sound reproduction. The transistors used for the buffer have an output current of 2700mAh, allowing the AMP8 to be used with IEMs or headsets requiring a high current. On the output connector side, there is a symmetrical 4.4mm Pentaconn plug with a wide double contact zone for low resistance and therefore better current transmission.

When designing a portable amplifier, it is almost impossible to use ÄOPs while achieving a high voltage and output current. Some engineers use a TPA6120 chip on the buffer stage to reach 750mA in output current. However, this implies an output impedance of 10 Ohm which is not ideal for the use of IEM or low impedance headphones.

Based on this observation, Ibasso has chosen to use discrete components usually found in larger amplifiers. The design of the device is therefore more complex, but this method allows a higher current and output voltage to be achieved, while maintaining a low impedance and ensuring very good measurements. The AMP8 follows this design model and can therefore accompany the Ibasso DX 150 and DX200 DAPs so that you can enjoy your music to the full.

un module ampli homogène
Acheté pour équiper un DX200, il remplit à merveille la tâche : le son est plus naturel sur tout le spectre, les basses sont plus présentes, et les aigus aussi, conférant ainsi à la musique une meilleure ouverture sonore. L'ampli original amp1 avec sa sortie symétrique 2.5mm se débrouillait pas trop mal, mais il lui manquait cette homogénéité : son trop "propre", trop "contenu" typique des ampli opérationnels. La contre partie : une autonomie en baisse, mais au service de la musique.
Enfin, les défauts que je trouvais à mon casque pioneer ont disparu aussitôt l'amp 8 installé. J'ai hâte de le tester avec un Senn. HD650 et son câble adapté en symétrique 4.4mm
