However, with their tiny budget, the analog and digital audio circuits in your computer are not designed with the quality of parts and sophistication of circuitry which would enable the computer to perform as a high-fidelity audio source component, fully honoring the fragile nature of audio data.

Beyerdynamic A200p Portable DAC Headphone Amplifier. Even top headphones such as the beyerdynamic T51p cannot be used to their full potential with mobile devices. The transformation of the digital sound data for the analog headphone playback seldom meets genuine hi-fi standards. The A200p from beyerdynamic is a solution to this problem. It meets demanding audio requirements and provides you with significantly improved sound on-the-go. The A200p circumvents the internal signal processing of the connected player and receives the pure digital music data first. After converting the digital data to analogue music signals, a high-quality amplifier controls the output to the connected headphones. All of this results in a level of audio quality that was previously not possible for travelling audiophiles. Previously unheard details, better contoured and deeper bass, as well as natural instrument and vocal reproduction transform standard portable sound into a true hi-fi experience. And buy this Beyerdynamic A200p Portable DAC Headphone Amplifier Now £269.00.
