Do you mean aragon 2004? Which version; mark one or mark two?
The 2002 is the 2-channel version of the more popular (I think) multichannel 2005/2007 family.
The 2000 family has had some really good reviews, and they are fine-looking amps, too. It would be a good upgrade.
My personal preference is the older 2004/4004, or the 8002/8008 families of stereo amps. Less gorgeous, more power supply for driving low-impedance loads.
