You should use your computer as the center of your audio system. Also you need to buy a quality DAC (Digital-Analog Converter) based on USB interface. Then you can play almost any formats except SACD. That's what I am doing for a decade. DAC will provide the following output interfaces;

(1) stereo-RCA

(2) Headphone jack

(3) Toslink interface

Then connect your stereo system through (1) or (3).
