i agree, don't switch unless your current amp is broke. for the record the rl-p would handle the wattage if you are careful. also there is this nifty little knob on the tantrum called a gain or input sensitivity, and when turned down can be easy on a subwoofer //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
those are two pretty good amps. does your rlp not sound good with the raa1000? b/c i powered two of my friends L7's and it slammed and didn't go near shutting down. listen to the pg if u want to, i know they're great amps and i used to rock the old school pg's. but if they sound the same, keep what u have, the raa1000 seems to be clean and powerful.
