Mr Watts emailed me few minutes after my post. I am just glad I bought it locally as it makes it much easier to have this sort of matters solved. I was using the Australian PSU provided and I have no idea about what my surge protection does with the polarity.
I did have the rca plugged in and the other end just loss, could the two rca touching each other might have cause it? I am not really sure, such stuff happens with electrical stuff, I am very happy with the sound and that what matters.
My local dealer already told me he is getting some stock soon and he is happy yo replace it for me.
My charger is not the PSU block that I've seen on the web, mine is just an adapter.
