If you like all aspects of your current system except the bass then adding a sub is probably the most logical approach. Getting bigger main speakers may give more bass, but you'll still be using the same amp, with its power limitations, whereas with a powered sub like a REL the REL's internal solid state amp takes care of the power hungry low frequencies.
I own a strata 3 and I love it ... best thing I ever added to my system. Perviously my system had great imaging and great vocal reproduction, but wasn't very involving. With the sub comes scale, dynamics and very, very deep bass .. deeper and cleaner than I've heard from any floorstander under $2000 (not that I've heard that many).
