G'day, thanks for replying. Yamaha RX A6A Amp, Rotel 1552 power amp, 4 x B&W 702 floor speakers (front/back), 2 x Tannoy Mercury (front presence), 2 x B&W PV1 subwoofers, Synology NAS server, Apple TV 4K. I have a huge library of 24/96 & 24/192 FLAC music I've collected and want to play the files at their best rate to get the most out of the speakers but I just can't seem to figure it out. Thank you
