Amazing 251 sound

Got this microphone over a month now and i'm trilled! This comes realy close with the original, who a friend of mine uses in his studio. We compared the two and it's almost indentical to the Ela M 251 from Telefunken. And for this price... awesome!! It's now my "go to" mic for solo singers.

Very nice mic!!!! only one thing I couldn't find the microphone diagram…..Please…. Good work

Superb

I never dreamed that I could own a 251 in my life. I received the kit today which was very well packed and I started building immediately. I have some diy experience so it went pretty fast. The build was very comprehensive and easy to do with the instructions. This is a beautiful mic to look at! But the most important thing. The sound… I’m blown away by the quality. I’ve worked with many condensers and never heard anything like this. It’s a very very good sounding mic. I like it better than any u47’s I’ve heard but maybe that’s just my taste. This has more of a pleasing curve to start with. This is truly ‘capturing’ what I want it to.
It fits my vocals amazingly. It’s super low noise and just deep and 3d.
I might post an update once I’ve worked with it longer. But for now consider me impressed

Awsome!

Bought a stereo pair of the M251 DIY kit. Never build a DIY kit of any sort before. Found it quite easy to put together the mic's, which is btw of superb quality. The mic's feels and sounds expensive, though their not...I'm so satisfied that I'm going to order the U67 kit in the near future🤩
