Interesting- My results are exactly the opposite of dres, and I own C3 and NTK. I find NTK more colored and darker, and very nice. I have found C3 to be the more versatile all around mic. Better, IMHO, for ambient micing, better for instruments, and with bass rolloff, pad, and multipolar capability, much more versatile. If I was only going to have one LD condenser, I'd choose C3, until I got to a higher price point. Then it would be AKG 414BULS, then a B.L.U.E. Kiwi vs. Neumann U87. I find tube mics in general to be beautiful for certain types of vocals, but I haven't found them to be so hot as instrument mics or room mics.-Richie
