Why Can We plug our AMPS directly into wall w/o Worrying?

hi all.

considering power conditioners for my system, and am stuck on why I can plug my krell amps directly into the wall without worrying about line surges, dirty power, rfi and similar evils... why is it so much more important to get 'clean power' to my other components and to 'protect' them, but so many people advise plugging the most expensive part (of my system) directly into the walls? are power amps somehow impervious to dirty lines and spikes? someone help... with my setup, i could just get a ps audio 300 or mit z center or chang iso 9600 for the components and go the amps directly into the wall, or i could get a more expensive device (ps audio 600, chang ht1000) that includes power conditioning for the amps... thanks again all for your reponses... -

Baz,
As Garfish intimates, "clean power" is important where the chain is most vulnerable: pre, digital front-end, etc. Power amps are less vulnerable (they usually have very large power supplies of their own), but they DO need to draw current -- hence the advice to plug directly to wall. Given the (often) high current (or voltages), power amps are also supplied with protection circuits that can save them in cases of surges (hopefully!). Finally, many power amps can reach optimum operation level from cold within ~hour; so, less need to leave them on all the time and unattended.
Cheers!

Ideally, heavy loads (i.e. amps) should be plugged into separate outlets. If you don't go down the dedicated lines way, try to use different outlets (from different lines) to plug in yr equipment -- rather than plugging everything into the same outlet (if that's what yr intimating). And yes, do plug the amp directly to the wall outlet....

Still beleive dedicated line to be the best option, though.

Good luck!
