The reason we don't recommend a PC powersupply, is because it is a switching powersupply. And they all are (or at least 99.99% of them). It is the only way to get 300-500 Watts of power from such a "small" enclosure. If you ever have opened a PC powersupply, you will notice that the transformer is tiny, it contains lot of electronics, and the remainder is heat sinks. Look at the powersupply of a typical 2x200W power amplifier, and the transformer is huge, weighing a few kilo's! -- tomsi42 SqueezeBox2, Rotel RC-1070/RB-1070, dynaBel Exact. ------------------------------------------------------------------------ tomsi42's Profile: http://forums.slimdevices.com/member.php?userid=2477 View this thread: http://forums.slimdevices.com/showthread.php?t=20844 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
