|Audiophile sound anywhere you are .......|
The second generation of R-2R USB/SPDIF portable DAC is available
This portable USB DAC have really R-2R multibit multiplying current-output DAC chip. This full size chip LTC2753 from Linear Technology Corporation have exceptional precision characteristics and use for avionic, medicine and science precision electronic. The choose this chip instead of usual NOS like PCM1704 or sigma-delta chips, allow us to achieve maximum fidelity of audio signal and therefore the sound of this DAC is really to hook and to nail. A nuances of sound sometimes verge to revelation. And the sound indeed fill of energy of music performance. Though for nuances hear you need a top range of headphones, or top - 1. With top line of headphones, a listener can to check of track record and to find all faults of audio mastering mix even. The most unbelievable idea is that little enclosure have sound performance as some or even better then it big AC-socket's brothers DAC + HPA from 5K-20K $ range. And this is not joke. Externally the DAC is seem a laconic. No buttons, no lights. But be sure all the to need for quality sound are include it, following our motto "world's maximum by hardware resolution" . The last technology of semiconductor market together with absent of unwanted LED lights allow us to make this DAC so efficient that can to avoid to implement of internal battery, and remove all worrys by charging it from your mind. This DAC don't custom driver required and supports by Windows, Mac OS-X, Linux, iPad/iOS and Android from 5.0 operated systems by native.

This different voltage output to give to achieve most best signal/noise rating and take to you more comfortable volume adjustment. (Note: A output of regular portable audio is 2.1 Vrms or 3 V peak-peak)
