Opinions on the best recorder to get for recording classical ensembles, using only 2 tracks, with a Royer 24 stereo mic and Millenium HV-3B pre-amp? Is there a difference in audio quality between the new digital recorders that are replacing DATS, made by Fostex, Sound Devices, Tascam, Nagra etc? The Fostex FR-2 preamps cannot be bypassed. The Tascam DV-RA1000 includes DSD recording.
