hey everyone, i am currently running the AT4041 mics with the denecke ps-2 for phanton power. i am looking for a preamp or ad converter to boost the signal. I have been looking at the denecke ad-20 (zefiro inbox), but what other things are out there for around that price (250 - 300)? one of the things i like about the ad-20 is that it runs on a 9-volt so i would preferably want to use something that will run on some type of battery. thanks for any help!
