^^taper I think he was referring to this.
I also purchased a dr-07 and have been happy with it thus far. I did read in another thread that the 24bit recording is not actually doing anything because the snr of the dr-07 is 87db. is this correct?
This is not entirely correct. Let's take the 87 dB SNR at face value, and assume it's a limitation imposed by the pre-digital-conversion bits of the circuitry. There's a rule of thumb (and yes, I realize rules of thumb aren't always exactly correct - in fact they hardly ever are, but they're often in the ballpark) that to keep the next component in an audio chain from adding audibly to the noise floor, it should have a SNR 10dB better than the signal being fed into it. (Again, I am not asserting that 10dB is the right number for all situation, nor that 10.1 dB makes a system transparent and 9.9dB makes it a hissy mess.) So, in theory, there might be some benefit to having more than 96dB (16 bit) available to encode an incoming signal with an SNR of 87 dB. Although odds are the signals coming in from your mics aren't that clean, especially at a noisy rock concert venue.
