Hi Kev,
I have no experience with the Warm Audio WA-251, but I do have experience with the Warm Audio WA-47. I started a thread on this subject
HERE.
I talked to my Sweetwater sales guy about the WA-47 before I bought it and he said that the studio guys had very good things to say about this mic. I have tried this mic on several videos already since I bought it and I like the sound of it.
Sweetwater seems to like the Warm Audio gear and gives the products high praise across their line of equipment. The reviews on the WA-47 mic tend to be good, suggesting that the mic is well worth the cost even if it's not an exact duplicate of the revered Neumann U-47.
