Increasingly disappointed with the sound of my aging stereo plugged into the headphone jack of my iMac ... its flat, little emotion, really poor despite basic elements of good quality (Yamaha amp, Cabasse speakers) .. . In search of a solution (amp change ...) across an article on the DacMagic Intrige ... ... bought ... It is dazzling, the difference is HUGE ... Connected between USB and amp ... simple configuration input output for those who can read, guaranteed results. Frankly not a very big luxury for the one who really loves to listen, regardless of the style of music include listening not only instruments "forgotten" (erased during the digital / analog decompression) but also, and perhaps above while a freshness and space.
