Tests by Avisoft Bioacoustics indicate that the DR07 and DR100
share the same preamp performance. It's disappointing that
you pay such a large premium for the DR100's XLR inputs, metal
case and Li-Ion battery. (DR07 = $165 delivered from
buy.comDR100 = $370 delivered from eBay. In both cases, the vendor is
"the deal spot.")
The Avisoft tests of preamp self-noise place the DR07 and DR100
in the middle of the pack, similar to the Marantz PMD620, and not
nearly as good as the Marantz PMD661 and Sony PCM-D50.
The Avisoft tests of portable audio recorders are the most complete
and most consistent ones available. To date, results are posted for
20 recorder models tested in 27 configurations.
The Avisoft Bioacoustics tests are controversial because they test
preamp performance at full gain and 16/44.1. The Avisoft tests are
conducted in this way because nature recording often needs lots of
gain (little bird singing from the top of a distant tall tree, for example)
