I really like the Marantz PMD620 also, i have a stock unit and use the HLSC-1's(4.7k mod) straight into the mic in with very nice results and no issues with clipping at all, in fact i recorded Testament in a small venue last week which was extremely loud and it turned out rather nicely as have all the recordings that way(done the mic in thing 4 times now), the unit provides 5v of phantom power which is plenty to power plug in mics so i really see no reason for having a battery box in loud concert situations which makes that setup very small indeed, i only have need for a preamp when its a quieter or acoustic type show.
