One of my professors is an ethnomusicologist and does a lot of field recording. He recently picked up a pmd 660, and like a lot of people I've talked to, is frustrated hissing he gets running mic in/line in. What do you think the best option would be for him as far as a pre-amp goes? I let him borrow my ua-5 last weekend and even the extra mic level control on the ua-5 definitely helped with managing those levels.
What's the best way to make this thing managable? I've heard buzz about the oade Concert mod? As far as the pre-amp options looking for a something small, managable and capable of external battery power. Or should he just sell this beast and get a pmd 670?
-Thanks for your help,
