Cleaning optical ouput port?
I have a vintage cd player (Pioneer PD-6700) and I wanted to upgrade it with external dac (SMSL SU-1).
First I had really bad connection. Audio was cutting out and input indicator was blinking.
I had only one old and cheap optical cable. I switched its direction and it did start working better but not perfect.
I went to buy new cable (also cheap), First it had again very much cut outs but when I blew the output connector with compressed air and got things working.
But now I noticed i still get few cut outs per album so problem still exists.
Is there a way to safely clean the optical output? CD player is decades old and I think optical out was never used before. Or can optical output just wear out and signal becomes too weak. Or are cheap cables just garbage?
