What you hear ist the quality of the MICS and not the recording device

. Mics are the most important parameter for a good sounding recording.
The Edirol doesn´t "SOUND", it´s the external MICS(and the acoustics of the venue and many other parameters!) which make a recording sound good or bad.
So each R09 sample will sound different as different mics were used for different recordings at different venues.
Focus your interest on "WHICH MIC" might fit best for metal-shows and not "which recording device" might fit best.
As long as it´s lossless (at least 16bit 44.1kHz) its ok.
