I had a chance to tour the Audix plant in Wilsonville OR last year. They have an impressive facility.
They lent me a D6 to compare to my AKG D112 and I thought the D6 sounded very good. Not the same as the D112, the D6 doesn't have as much click to it as the AKG.
I used the D6 for a while but have recenty reverted back to the D112 .. I just like the AKG better..
