I’m sure TY knows his stuff, and after more than 10 years as an audio engineer, I feel that I’m pretty cluey as well. I’ve never at any point said that dynamic mics don’t require more preamp gain, my point is that in an untreated room that hasn’t been soundproofed, the advantages of a condenser mic may actually prove detrimental to the end product, as reflections and background noise will be picked up more easily. For VO work, you don’t want to hear the room, and you definitely don’t want to hear anything beyond the room.
My recommendation would be to spend a chunk of the budget on acoustic treatment. Soundproofing is a whole other issue, but if your room is sorted, absolutely go for a condenser. Craig, I’m a recording studio guy, not a field audio guy, I think Sound Devices stuff is for portable recording. Is your unit battery powered? If so that might be why it has less gain available, and if you dial it all the way up for a dynamic, it probably will add noise and/or become less linear. A studio mic pre shouldn’t have this issue, as they run on mains power.
