Dig it. Chrissy Cunningham has a blog. I got my apartment from her! So read her blog. Do what she says.
TC Electronic makes some interesting hardware/software. I liked my M5000 a whole lot. It was really nice. It finally died. It had two engines. I feel like an old guy talking about his car as a teenager. I mean, I was in my 30's when I got it. But you know what I mean.
Handbuilt tube consoles. With DIY options available.
I feel like one could make either a box or a plugin that would make an audio source have that 3D "depth" that we tend do like from old, mono, large diaphragm microphones. You know how a single microphone sounds like it's coming from beyond a speaker? That special depth from a modern source is what I'm after. I suspect it has to do with phase weirditude. Perhaps strange adjacent EQ's boosting and cutting.
