Spinitch,
I can't offer solid guidance because I've never heard your table. The following is my generic $.02. Perhaps someone who knows the Radius can offer something more specific.
I've tried something like your Option B by putting high end cartridges on a mid-fi (ish) table and arm. Afer the initial flush of amazement at what the cartridge could do, the experience became unsatisfactory. The cartridge revealed more about the inadequacies of the rig than it did about the music. Listening to that particular mismatch grew more distracting than enjoyable, at least for me.
I don't know if a TriPlanar would fit on a Radius but I'd be reluctant to recommend it. There isn't a more revealing/less forgiving tonearm anywhere, at least IME. If a table has ANY noise, resonance, rumble, speed or other issues a TriPlanar will expose them. That will be doubly true if you mount a good cartridge on it. (OTOH, a Teres + TriPlanar sounds magnificent even with just an entry level MM cartridge. I could listen to that kind of setup very happily.)
Between table, arm and cartridge, IME the table must be brought up to standard first, the arm second and the cartridge third. A better phono stage certainly fits in there somewhere too, but that's harder to prioritise without getting specific about makes and models.
FWIW, I vote against option B, unless it would be a pretty short term stopgap before upgrading the table.
