It certainly applies to cars, but not as far as I know to refrigerators and so on. Perhaps the devices that have 'static' performance are left alone simply because they work and there is no perceived or noticeable benefit to upgrading.
Cars and hi-fi have a more 'dynamic' performance envelope, where components can be changed at relatively low cost (springs, capacitors, turbos, cables) to alter the original price/performance tradeoffs, and also to alter aspects in specific areas of performance (handling and the expense of comfort and road noise, better immunity to power supply noise, acceleration at the expense of noise and fuel consumption and so on). For the latter type the original designers met the requirements with a compromise, at the intended cost, to be of most use to the general customer base. Substituting another better component can frequently make an improvement, in many cases this would have been used by the designers if the cost specification had allowed it or if the requirements had been specified differently. -- karma mechanic ------------------------------------------------------------------------ karma mechanic's Profile: http://forums.slimdevices.com/member.php?userid=8868 View this thread: http://forums.slimdevices.com/showthread.php?t=31061 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
