ive got a 620 here
seems nice and starts quick
compared to a zoom h2 i tested in a store find it difficult to aim toward a certain noise source as mics seem to want to record 360 degrees
also, i wonder if it or any device can charge batteries while they are inside so that they dont need to be taken out. though marantz sems more robust compared to edirol, batteries come out easier out of the edirol
and has anyone made tests how long it can record in 16 bit 44.1 wav or 192khz mp3?
a firmware update would be good to make it record 320k mp3
