The bra intrigues me too!
Seriously though - we have so m much headroom nowadays that clipping is almost a feature of the past - equally, with the noise floor so low, a recording that doesn't get close to the top is not an issue either. I have to own up to looking at my chair, looking at the interface in the rack on the wall and thinking do I really need to get up and turn that knob from 6 to 7, or down to 5 - so I don't bother. I can't remember the last time I had a clipping problem, and equally, if I listen carefully sometimes I might have recorded a bit of computer fan noise if the door to the cupboard where the computers live was slightly open. I just cannot ever imagine using a plug in when it's just easier to know your gear well enough to know how clean recordings will happen. I know that I will have to get up and tweak the gain when I put a 414 or 87 on a sax, close in for the tone. Equally, I know if I pick up an acoustic guitar, I won't if the thing I recorded last is the same ballpark volume.
No hums, no buzzes or interference. If I got a hum or buzz, I'd not use a plugin, I'd fix the damn thing.
