The Solisto.HP-Amp is a high quality headphone amplifier and supports the use of very demanding headphones due to its high power output and other characteristics.

The Solisto.HP-Amp features a variety of audio inputs that offer great flexibility. In addition to the standard analogue line input, it is equipped with both optical and electrical digital inputs, supporting a range of sampling frequencies that reaches the professional level of 192 kHz.

Audio systems for hi-fi and home cinema are becoming ever more complex and interlink with a host of different digital and analogue devices. The Solisto.HP-Amp is designed as a very versatile tool, able to connect with the different parts of any such system. The device is optimised to deliver excellent audio quality while offering best value for money.

In many of these cases the Solisto. HP-Amp helps by adding a high end headphone amplifier that connects to both optical and electrical digital outputs of your hi-fi system or any kind of analogue audio source. Another advantage is the stylish, high- quality aluminium housing with a blue light at the front indicating an audio signal is present, thus it is not necessary to hide it.

Please note that the Solisto.HPAmp cannot convert signals such as Dolby Digital, AC3, DTS, 5.1 etc. In such cases, the device – e.g. a flat screen TV – needs to be switched to a normal stereo signal.
