AC Filter necessary?

I was told by a respectable power company that Amp and Sub are able to protect themselves. They recommended to plug the Amp directly into the wall. This will allow the Amp to draw more current. My Amp is plugged into the wall for the last 6 months and without any problems.

Rodney,

The NAd amps have a built in power cord, non replacable. I'm using a 50w per channel amp. Have you had power surges while your amp was playing Rodney01? It just worries me that I could dmg hundreds of dollar worth of equipment due to a power company error, etc.

Buy a Tice unit.. BIG improvement in sound.. I would not plug anything into the wall after hearing the Tice improvements.
