True Steve.
You can remove the toob on the 107 and I discussed this with Jim Williams before.
Unfortunately, the gain it helps provide is around 15 dB IIRC.
So would be fine with most condensers, but may not be for applications involving dynamic microphones, especially on quiet sources.
Would have tried my B1, however, it just got sold on ebay.
The room acoustics at home are poor, so it's back to only using dynamics for at least some time. If and when any are wanted, planning to get one or two of
Ethan's MiniTraps to help get things under better control at home.
Shell is probably right, based on some research I just did, thinking these are the same pre's as in the DMP2 (not DMP3). Still they're reputed to be nice sounding.
As my preferred recording option right now is 4 track minidisc (gasp!),
and also likely to be using the Ableton program later on,
"which pre" has become much less of a concern.
Between the prosumer A/D of the MD unit, and staying in the box with a computer
program, why worry?
