Hi Guitarfx I'm a noob here. Thank you for the great & indepth review and the samples you've posted. Really useful. I'm deciding between the Tascam and the zoom H4. I'm looking to record in the field: nature sounds, ambiences etc, so the quieter the preamps the better. Have you tried recording ambience's? Do you think the Zoom H4 has quieter hum/noise than the Tascam? Thanks very much! Rounik
