I wonderif anyone can help with an issue I have with my NAD 325BEE. It won't boot up. The unit is plugged in and the standby light is on, but when the power button is pressed nothing happens. Usually there is a second or two delay then a soft click and the amp comes to life with a green display light. I suspect that there is a fault with the relay that kicks in when the standby on button is pressed. This is the second time I have had this problem with exactly the same make and model. Perhaps its a design fault? should I contact NAD and ask them? Its 3 or 4 years old so well out of warranty.
