Topic: a few questions about adi 2

Hello i want to ask a few question about adi 2 dac.


How fast you can change the output from headphone to speakers and vice versa with the new remote and without it, i mean from the device only.


Can you tell me briefly, the stages of the amplifier for the headphone ouput/XLR and what IC you are using ?


Is there any type of usb isolation ?
