Having used a modded Aragon 3002 (300Wpc), which was a very good sounding amp, I switched to tubes, a VAC PA 35.35, for a considerable uptick in sound quality. I can't comment on how such an amp would match up with your speakers, but I do know a better amp will make a difference. You might consider some mods on your Aragon, that can make a real difference, if you really like that particular amp.
Good luck, regards,
