I have just read this very clear paper on SD website about the 32 bit float resolution, and... I am blown away. 1528 dB of dynamic range, a headroom of 770 dBFS ABOVE our standard 0dBFS !! I understand now why the MixPre series is so popular amongst sound designers.

But now comes to mind an obsessive question: if gear designers like SD and more are capable of creating machines able to record files in 32bit float resolution, why have they not implemented it in their pro range recorders (like the 8 series for SD) ???!?
Anyone capable to clear the mystery for me?
Thanks
Fred
PS: I understand that the actual dynamic range limit of the recording is that of the preamp and AD converters, yet it seems like a new world to me (remember I started on Nagra 4.2 😉
