I just came from an audio show and noticed many of the systems are using macs hardwired to the stereos as their sources. Most recent Macs that I know of like mine have fiberop (toslink) in the headphone jack if you use the adapter for fiberop. This is what I have been using, however, it seems most vendors are all using USB instead of the toslink capability fed into their DAC's. I do have some hi-rez music files (176-192 kHz). I have not noticed if these are actively playing through my system or not as I believe toslink is limited to 96 kHz. I know my DAC (Bryston BDA-1) USB is limited to 48 kHz so am I to assume they might be using DACs that are accepting higher sampling rates using the USB connections? What about using my MBP's firewire or thunderbolt connections converted to HDMI?
