i ran the Pocketrak CX before the Tascam DR07 and yes the onboard mics harm to overload, but they are quite good maybe on Events where the SPL is limited to around 100db this is a quite good recorder.
It can run very long on one AA Eneloop battery, and when you switch it off, its is really OFF - The Zoom had a bit issue, when switched of it took the battery out of juice, maybe they fixed it now with update.
Pro Zoom: it can do seamless recording for 2 GB file split, the yamaha canĀ“t (all manuals say it need 2 seconds), so the 24 / 96 Mode on the Yamaha W24 is rather useless for concert recordings. or maybe has to tested out with an fast SDHC memory card - before recording some important things.
