Cheap amps with no switch-off thump to replace Behringer A500 for driving active tweeters?

Thank you all. Lots of good ideas.

I wonder how I can find out whether the Behringer A800 has switch-on/-off thump. Obviously I tend to leave my amps on, but SMPS amps might be better for the lecky bill as well as solving the thump.
