Sorry to hear that Mario, I hope things work out well then... I've been lucky with my Duelund caps so far (Steven replaced it with a new one before I bought my killerDAC). How did your caps fail? How long have you been running them?
i was setting :' up my mates system with some ml1+R and a sub it all started well then we started to hear a distortion in the midrange.
the volume would only work at the lower end of the scale.i thought his volume pot packed it,so i changed it and still we had no sound at louder levels.by swapping interconnects from left to right channel i worked out that its the dac.so i took it home got my multimeter out and tested for dc voltage on the output.left channel 0.00 right channel 51v dc.took the cap out and put in a auricap no more dc voltage on the channel.
my right channel is stuffed aswell but i have a input cap on my amp so i can still listen to music.
caps have 18 months usage
not to worry the main thing is it can be fixed thank god i know that dac inside and out
