Then it explains it all



(sorry, could not resist).
But seriously:
Well, yeah, but again... you still don't know if MS would work in your situation and would be the best solution. I would not throw that much money into something you still don't know. Who knows, in your situation maybe Blumlein would be just fine or:
I wish you gave this info about your "padded room" earlier, as in that kind of situation even spaced "true" omnies might be nice, esp. if you have curtains and carpet.
As I have already said in another thread, I am afraid the LD selectable pattern omnies do not work nearly as nice on classical piano as SD "true" omnies--been there, done that. From my experience, the fig8 LD selectables do not work nearly as nice on classical piano as "native" ribbons, so I have very little clue as for what would you accomplish with the NT2A's.
First, you should be extremely careful with ANY microphone, whether it is ribbon or condenser! Second, you don't hold the mics in your hands, the mics are permanently on your mic stand--you just put something protective on them when not in use. Third, common... is the dropping the mic can be a good reason not to use it?
This GA stuff looks exactly like rebranded Apex205, or Nady, or hundreds of other mics, which came off the same factory. I don't see anything particularly interesting in that. If your decision based on the reviews, could you tell me how many of them checked those mics on classical piano. On the other hand, have you ever seen one single bad review of a ribbon microphone?
What I'd do in your situation before anything else, from ebay I'd buy a second hand pair of SP C4's, which have both cardioid and "true" omni capsules. Along with that I'd buy a pair of "Royer copies", i.e. Stellar R3, or whatever else name they come under.
That combination will keep you busy experimenting for quite awhile. Once you find the sound you are happy with, then you can sell that stuff without loosing much money. You can upgrade--there are quite a few good choices, and modifying is not the last.
This, and only this will give you a clear plan; this, and only this way you will know exactly what you need and will be able to invest your money smartly and thoughtfully. Otherwise... well... I won't give an example about "candy store" again...


Hopefully, it is helpful.
