So I have a pair of Naiant X-R omni capsule and dual RCA cables that terminate to an 1/8" stereo plug. Right now I'm running a Tascam DR-60mkII, which has 2 XLR inputs with 48V phantom and an 1/8" stereo input for channels 3/4. My main pair of mics are Neumann KM184s that I run into channels 1 and 2 with phantom. I've run SBD feeds into channels 3/4, but have the X-R omnis to have options to run a second pair of mics (looking at spaced omnis for outdoors mostly). I've been in no rush to get gear, so looking for opinions.
So the PIP from the DR-60 isn't enough to power the X-R caps. So I'm looking at either a battery box or getting a Naiant IPA. I'm looking at either a Sound Pro 9V with no bass rolloff (which is ~$70) or going the for the IPA which will run ~$110 but give me gain boost and also can be used down the line if I ever move to an active setup, etc. I looked at the Church BBs which are cheaper, but when you add in the shipping Chris charges from Canada (and the wait time) it comes out around the same as the Sound Pro.
Any thoughts? Thanks!
