You will notice a HUGE IMPROVEMENT IMMEDIATELY, trust me/us
I would try the CA11>9100 asap and let us know what you think of that combo. If you end up liking recording with mics/BB/Preamp/etc. then go and buy the CA14 Omnis AND Cards
That way you would be covered wherever youre recording from and at around $100.00/Pair for Cards and omnis, and around $100.00 for the Battery Box/Preamp and I would use the Tascam DR-05 over the Zoom. Zoom are just known for cheap/shitty quality, and their handheld recorders are no exception IMO. I would much rather trust a Tascam unit and some Church Audio gear
