Exactly - think how expensive and critical a satellite is. There are tens of thousands, hundreds of thousands of solder joints. Every one must be carefully inspected - there are actually "solder engineers" that do this. Every cable must be tested and checked as well. You don't want this to fail in orbit! I wonder if those guys believe in the concept of burn-in? I don't think so. While they do power it up and leave various circuits running, this is only to test it and make sure there are no defective components (if it runs for 100 hours on the bench, it probably will for another 100 000 hours in orbit), not to let it burn in. They would definitely not want the operating characteristics to drift over time. The only pseudo-scientific explanation for burn-in I've seen mentioned is "electron creep". Sounds shaky at best, and google can't even locate any links on it. > On the other hand your ears/brain are going to percieve changes whether > or not they exist. So you decide which is more plausible... Yes, the brain will adjust and get used to how things sound. You even get used to speaker colouration - extremely flat FR speakers aren't usually perceived as pleasant because our minds grow used to what less-perfect speakers sound like. On subtle things like sound, our brain and how it perceives/interprets it plays a very large role. It can completely fool you, which is why ABX tests are so important. -- Mark Lanctot ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=29025 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
