My sample space isn't big enough to be definitive either. I have never had a failure with electromechanical devices (players etc..) but have had several problems with receivers. In nearly every case the manufacturing had just been moved to China, so this may be a temporary learning-curve thing, not sure.
Like they teach in first year psych (which for engineers is mostly statistics, ie almost no girls), there may be other things skewing my results, like the belief that I can tinker with something mechanical without voiding the warranty but that it's unlikely I can desolder and replace an electronic component without getting busted
