Until now, when high-quality sound was required for terminals such as smartphones and tablets, it was necessary to connect a large external portable DAC amplifier to the terminal, and there were few cost-effective options. The ITM05 was developed as a compact, high-quality portable DAC amplifier to solve these size and cost issues. By attaching ITM05 to your mobile device, you can easily evolve it into a portable player of middle class or higher.
