Disclosure I have not tried this mic , That said:
Warm Audio is a USA based company that has a reputation for bringing classic design based hardware and mic's to the market, at affordable prices. They design and spec the products and have them manufactured overseas (in China) I believe, to what they claim are exacting standards .
Perhaps anyone who has one of their products can offer perspective.
For those that may not be aware the Classic Telefunken ELAM 251 is one of handful of classic mic designs U67 ,, U47,, C-12 ,, that have survived the test of time and are still considered to part of recording legend.
There are numerous modern mics based on and trying to reproduce these classic mic sounds in all price categories .
Interestingly enough early this fall I decided to finally get a good tube mic.
I had pretty much decided to get a good U47 or U67 inspired mic and had budgeted about $3k . And ADK came to my attention.. In a studio audition side by side comparison (my to surprise ) I chose the 251 based mic as the best sounding on my voice .
So back to OP:
IF this Warm Audio offering is even 70 - 80 percent there, at 1/3 to 1/4 the price of my ADK, and over 1/10 th the price of the current Telefunken 251 price, it could well be an excellent value in mic choice .
