Well having got my 552 and ps, back from a full service and dr, earlier this week, on first switch on the left channel was completely dead, i left it switched on and went back to work, but i did contact the dealer and told him off my problem, he then contacted naim and told them.
Anyway i got home from work about 5 hours later and it was all working fine, and its been like that till this morning, when i decided to turn it off, as i wanted to move the 500 up a level, after doing this, the left channel has gone again.
I have tried the 500 and its fine, all working fine when running direct from the rossini.
I have also tried and checked all the connections and all are in the right way, and nothing looks wrong, when i look at pins etc.
So it looks like its got to go back, which is a right pain and one i could do without having to sort out right now, but other than a faulty burndy cable, its got to be one off the boxes.
I can’t see how the burndy cable has gone, plus if you wiggle it about, nothing happens.
Anyway errrrrr is all i can say, and not a happy bunny after spending quite a bit off money on it.
