I skimmed the Sound Devices 2016 patent for 32 bit (most of which is way above me) and note that it does describe 3 and 2 converter layouts, but noting it could be any number. I did not recognize any comment about the converter handoffs and noise control, but that could be me. I note that other manufacturers have to avoid infringing on their patent, so maybe SD understands the issue better and has the secret sauce in their patent. It would be nice to know if SD uses multiple converters in 24 bit mode, I haven't heard any issues and have not done much 32 bit.
On the clutch, I just prefer manuals as more fun. Today's automatics get better gas numbers and track lap times, but on the street that's not everything for me. I like road and machine feel, although most Americans apparently prefer automatics. I also don't use the phone while driving, even hands-free (legal requirement here).
As to the anti-theft aspect, I had an Integra manual for many years with a Club steering lock that was stolen 3 times, the last time driven 100 miles away and totaled. Integras were theft targets, so the thieves certainly were not stopped by a clutch or Club.
