I've tested all the major small audio recorders and the C100 blows them all out of the water in terms of signal to noise ratio. The Zooms, Marantz, Tascams, etc, are in no way comparable to the C100. I've been shooting interviews for the past year with my C100 and have been very very pleased with the results. No hiss at all when using my Sanken Cos11, Rode NTG3, or Sennheiser wireless kit.
