I bought an ESD strap today,but he who sold it to me said to eart myself on the case that I was working on and not what i belived on a radiator or similar.
Is this the way to do it?

Indeed, lookie lookie, same cheap enclosure L

First listen impression is also very good.
Cled is below the pcb, soldered at the led's pins.

Changed the dac chip and the regulator and now its working..
Listening from my computer Spdif out from my ASUS card and a discrete buffer after driving the HD650.

Well,I connected it to my stationary computer from the Spdif on my Asus essence one soundcard,and it sounded okay...
Then I connected the DAC to my laptop wich has the Hiface USB to Spdif interface now it started to sound better infact it sounds fine,clear highs and deep bass.

I wonder why the Spdif on my stationary don´t sound so good?
