I have a pair of old AKG D202 dynamic mic's, a pair of AT condensers (electret), and two Royer R101 ribbon mic's. The ribbons are very good for piano and strings although one of the mic's has a wobbly shock-mount even though only a couple of years old, which I need to fix.
So I thought an additional pair of condenser mic's (non electret) of reasonable quality would be good.
Did I mention the Avenson ST02 mic's which got a good review in SOS?
The ADK mic's are new to me as I hadn't looked at large diaphragm mic's, because i understood that small diaphragm mic's were better for instruments like piano and strings. Perhaps I've mis-understood the reason, but I thought they were better for faster detailed responses.
Ah! My fault... I hadn't realised that the Avantone was an SD.
Yes; I'd agree that I'd normally use an SD for many orchestral instruments. I'd also not wish to introduce too much character, but get as faithful a capture as possible. So... forget the Thor.

Afraid I don't know the Avensons at all.
I think the Line Audio mics have been suggested to you previously. They have a very good reputation and several here whose judgment I trust absolutely are pleased with them. If I was in the market I would be looking at those...
For your budget a pair of Rode NT55s with cardioid and omni caps come in right on budget. A firm favourite here. (I have the NT5 - cardioid and no pads - as a matched pair and am very pleased with them.)
Many here also like the Oktava MK02 - which you can get as a matched pair with cardioid and omni caps.
I'd also be looking for reviews on the JZ BT-201/3 which comes with three capsules. They produce some interesting mics....
But as I've already said, the list of mics in this category and price-point is very long indeed!
