Tracked my first demo vocal session with this microphone, and I really am impressed. I don't own a real U-47 and I honestly don't care how close this gets to that sound; all I care about is whether this mic sounds A) Good and B) different from my other microphones. A) It really does sound good. I haven't had time to try it out on a big variety of sources yet, but on a male vocalist who, on many mics, has a somewhat shrill, ice-pickey thing going on with his voice, this worked wonders. I actually ended up adding a 2dB shelf around 12KHz, and that was the only EQ the vocal needed. B) I guess I kind of addressed this point already in the A-portion of my review, but I'll reiterate: while I can't tell you if it sounds exactly like a stupifyingly expensive vintage Neumann, I can tell you that it doesn't sound like anything else in my (as of now, very modest) mic locker. I don't own any other tube mics, so it's possible I could have gotten similar results with the Rode NTK or K2 and saved some money. But I did like Warm Audio's reputation for quality, and maybe if it turns out their recreation of the old Neumann U47 IS spot-on accurate, maybe... just maybe... it will make me sound like Frank Sinatra. ¯\_(ツ)_/¯ One last note on my first impressions of build quality: This microphone is heavy (which obviously doesn't on its own necessarily speak to quality, but it does evoke something of a premium-ness in the overall presentation). It feels like it's well-built. Only time will tell read more if it's as solid inside as it is outside, but I'm relatively confident that, if taken care of, this microphone will outlive my particular breed of sound-nerd (you know who you are, with your closet full of black T-Shirts and your social awkwardness and your daily diet of Taco Bell and Mountain Dew). The microphone's wooden storage box is a nice touch, though I do really wish Warm would have included a storage solution for the whole ensemble. A little wooden box looks lovely on the mic shelf, but a case that could hold the power supply and shockmount and the fancy Gotham Audio cable would be even better. I (and I believe most potential buyers) would be willing to pay an extra $100 AND forgo the wooden box for an all-inclusive case of some sort. For now, guess I'll store everything in the cardboard box it all came in, though I have a feeling this mic is going to spend most of its time on a stand.
