I'm posting this because a few people asked. First of all, if you are an objectivist, go away. This project employs a microphone capsule that doesn't have a flat response. It's also a transformer coupled (NOT transformerless) design with a single active component, a JFET, where I intentionally chose a resistor to bias the JFET for higher second and even order distortion. I had been looking for a large diaphragm transformer coupled microphone, particularly a vintagey sounding one, for some time now. The problem is that they don't make 'em anymore. Well, they actually do. But the problem is that we would have to cough up around $4000 for Neumann U47 FET. That's bullshit. I know Neumann is a respected name in microphones; but I f'ing hate them. Over the decades, they've cheapened their microphones while keeping their prices astronomical. It's for the mystique, the brand name. @Psalmanazar and I talk about studio gear every now and then and we joked about recording studios may have a Neumann on hand just for the cachet, but in reality probably use other microphones. For this project, I pretty much used the parts from the micparts T-47 kit (https://microphone-parts.com/collections/microphone-kits/products/t47-microphone-kit) with the exception of the capsule which came from @Soliloqueen. I can't down turn playing with creations from fellow members, encouraging them to make good shit. This capsule is intended to be similar to the K47 capsule of the U47 which has a bump in the presence region (it's intentional) and is still under development. Note Sonicap boutique part and good WIMAs that would make Dannie Ritchie proud. Anyway, I feel like I've scored a fantastic deal with a little bit of elbow grease. I know that my current gear (MOTU Ultralite mk4) is not anywhere good enough to capture the resolution, texture, and nuance that this microphone is capable. It's the nature of the design: a single transistor (JFET) followed by a transformer. The downsides are higher distortion, especially at higher SPL, which limits max SPL. This is a different approach from more modern designs with tons of transistors and super low distortion. Many modern microphones even employ opamps - yuck - which is even another step backwards in terms of capturing the immediacy and nuance of recording. The first question I often got was this: was this easy to build? My answer is that is was brain-dead easy. It's million times easier to build this than to repair most Modius DACs. I do have a decent amount of experience with soldering irons and had only gotten better because of necessity. However, I still think it's an easy first time project. I will cover some bases first.
