I was reading about something about leaving devices plugged in. Fire service advice is, do not leave anything attached to mains electricity unless you have to, like a fridge. I don't know, I suppose Chord DACs might fit that category.
However, I have a question about powering on. If I have ever unplugged my TT2, when I plug it back in, it powers up. Yet it did not do that when brand new. I clearly remember starting the TT2 by the power button. It was quite the experience. I haven't used an inappropriate linear power supply, as I do not have any.
I am worried about electrical safety in the TT2. Maybe a power surge etc, if I plug it in. Plus as far as I recall, its behaviour has changed.
Finally worked out what you mean. No mine has not done that so far.
