Chaner, is this the Mic you refer to from microphone parts? Interesting that it's available in different patterns and in a kit form as well.

Pretty much, although it looks like the snare mic that you linked is the high-SPL version. On closer inspection of their site, they have 2 different small-diaphragm stereo kits:
Once is based on Schoeps CMC5

https://microphone-parts.com/products/sdc-84-microphone-kit-neumann-km84-style?variant=9618652921916Keep in mind that the above links are for their DIY kits, which means they come UNASSEMBLED and you have to solder all the components together. For a couple hundred dollars more, you can buy assembled kits. They also only include one set of caps, you can buy matched pairs at $314. That's really expensive if you want a full set of caps: You're looking at $1600+ if you want card, omni, and hyper caps and you can't or don't want to solder.
I'm definitely not trying to hawk these at all, I'm simply curious if anyone's tried these and I wanna hear what they sound like. Unfortunately there's WAY too many companies out there that make outrageous claims about cloning and years of R&D (rolls eyes) etc. to consider these guys any different.
With that being said, the one Roswell product I own has proven useful, and I think I tried 4 different LDC's for voiceover work before I settled on the K87. The at4040 was the closest to being acceptable, solid noise floor but just too bright. I even tried one of my CM4's but a hair too noisy.
I do think the concept of selling DIY kits that you put together yourself is kinda cool, although I wish they were cheaper. If you read their reviews you see a few people mention that they actually messed up the build and then you're SOL.
