Guy, you would have to sell your speakers on the Axiom auction, then that money can go towards your next Axiom purchase.
I've never done a side by side comparison in the same room, but I would always take my M60's, or now M80's with a sub, over my M22's and a sub. Maybe it is the type of music or levels I listen to, the floorstanding speakers give you more impact due to the larger enclosure, even if you use a sub.
For music, I've never found a sub to make up that tight bass you get from a good floor standing speakers.
