^ Only comments about PR2ii in that clip is that it incorporates the new quieter preamps from the PR4, and that stereo mode remains 24bit only.

And as we speculated early on here at TS, he confirmed that when recording in stereo the twin paths through the 32bit AD converter are split to provide two separate 24bit channel paths.
If it has also been configured to accept a hotter mic-input before overloading, or alternately provide switchable 5V mic powering when set to line-input sensitivity, that change would address my biggest qualm with the original PR2.. along with switching the metering to peak-hold.
Of course I wish it were also upgraded to provide 32-bit stereo recording as originally promised..
mostly because that would incorporate all the hardware bits needed to allow for recording 4 channels in 24bit mode, like the Tascam DR2d was able to do since 2010, except also providing 5V mic-power to all 4 channels. This would use both locking TRS jacks as stereo inputs, the headphone/line-out jack serving as the 2nd stereo input. Please please please.
