Soldering does not require lead to work. If they can't solder without lead, then they were probably sloppy with it.
There are simply a lot of low quality electronic components coming out of asia these days. Some however, are not low quality.
Personally I had sony everything since 1988. Put a sony receiver and CD player in my truch in 1996. The CD player started to skip at times I thought it shouldnt, and the tape deck on the receiver went sour. I have a surround sound stereo in my house that has always worked. But after so long I begin to question the quality of the way it divides the sounds between the speakers. I have a sony DVD player that has trouble with minor scratches.
One way or another, I am done with Sony. My new Receiver is an Integra. Im looking for alternate brands everywhere else. I guess Sony got on the cost cutting bandwagon...
