Of your options, go with #1 - the Gold 200s.
I have 300GXs and they’re fabulous. Took some experimenting with amps - I wound up with Exposure 3010S2 monoblocks in preference to M700s, but the preamp and CD transport are also Exposure, so that makes sense.
The 200s are terrific speakers, and I think well worth it over the 100s - if your room can handle them.
