OK. I'm really not sure if it was the new firmware that enabling 24/192 playback on optical anymore. I have switched a few toslink cables and only one works. And I have confirmed signal in is 192kHz by pressing & holding the source button on the remote to show the input signal. Really puzzling but I'm not complaining. Now I can listen to 24/192 on my optical input with Bluesound Node. [/Grin]
