**********solved************ Hello All, Ive been using the Asus Xonar STX 2 for my PC music library, RCA into my Yamaha AS-500 for a few years and all good. But as things have moved on I decided to move with it, and I'm excited to receive a Cambridge CXA80 and CXN tomorrow. However, I really have no idea how I'm going to connect the PC to the Amp or the CXN. Are the CXA80 dacs an improvement over the STX soundcard? I really have no idea. The easiest would be BT dongle but I understnd "its not there yet", so what would give me the best connection? RCA from the card into the amp? would this make the onboard dacs surplus ? USB from the motherboard to the CXN ? Whould this make full use of the Cambridge processing? Optical from Soundcard to CXN? would this cause processing issues? Thanks guys.
