I've heard a lot of good things about the Denecke PS-2 for providing inline phantom power to mics.... I've seen it around the new new for $150, which is really high in my opinion. I've seen the Art Phantom II power supply, which as far as I can tell, does the exact same thing, for $42 US on ebay buy it now. Can somebody tell me what the difference between them is.. and whether the ART would be suitable for taping? Thanks..
