Vintage Neumann U47. Prices are all over the map on these, but most I've seen are about $5,000 if you can find one. A friend had borrowed it for some tracking, coincidentally at the time that I received my first Joly modded Oktava MK319. So I took the Oktava over to his place so that we could compare the two.
We recorded acoustic guitar and vocals. The results stunned everyone. 5 people with recording experience listened to the clips. 4 out of 5 preferred the Oktava on the acoustic guitar used. Interestingly enough I was the one who picked the U47 in this case. And 5 out of 5 preferred the Oktava on this particular vocal. The Oktava also handled sibilance better than the Neumann.
