They are $1,250 because they are made in Finland, I know it doesn't necessarily add to the sound quality but it is a legitimate reason for the premium. The KH80 are currently selling for $1,000 new and made in Ireland, though not exactly cheap labor either, I'm sure if they were made in Germany the price would be similar to the 8320a.Consider two things here.
1, the cost. They're $1250 a pair new.
2, the competition. Neumann KH80s are right around the same price point (maybe a bit cheaper, even) and their distortion performance is far better.
