Or do you want to increase the transient power       handling capacity of the amp? Seems like you'd possibly be stressing       some other part of the unit by beefing up the capacitators.                     --       The fashion in killing has an insouciant, flirty style this spring,       with the flaunting of well-defined muscle, wrapped in flags.              - Comment from an article on Antiwar.com (http://antiwar.com)              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
