NAD Reliability

There seems to be a global pressure to push out new electronics at ever increasing rate with most of the production being done in low cost Asian countries specially China. NAD always has been a high value company making musical components at a fraction of most of the competition. I was on the band wagon in 1979 to purchase their musical integrated classic. It seemed to last forever till giving up the ghost in this century as part of 3rd system. However, I have heard rumors that their most modern offerings are suffering less quality control and/or lower reliability. Specifically has anyone had reliability problems with their flagship M3 Integrated and if so were you satisfied with service quality and cost?
