It would be beneficial to know what the various CD player manufacturers advise about this. They're the folks who should know this intimately. Is the machine's life shortened by leaving it powered up all of the time? Yes or no?? Does the power supply stay warm and if so, would this cause it to wear out sooner? If the circuit board components (capacitors, diodes, etc) stay energized all of the time, would that shorten their opeational life???
Good stuff !!
