I decided to go with the DR-2d. I got a new laptop and the recorder. I haven't gotten to use it much but did record one band in a bar Monday night. I used the internal mics at low sensitivity with the gain set to about 75. I ended up having to raise it a decent bit. I was being cautious because I didn't know how it would handle the loudness yet. I had the recorder set on a table about 15' back from the stage centered. I also had my D50 and CA omnis/CA9000 on a tripod up about 7.
Overall I think it sounds pretty decent and seems to handle the louder bar type music I'll be recording pretty well. The internal mics are fairly flat to my ears.
I attached a short sample from each one. Sample1 is the CA omnis and CA9000, sample2 the D50 internal mics at 180 degres, and sample 3 the DR-2d internals. I bosted each and dithered the D50 and Tascam to 16 bit but there is nothing else added. For my final mix I did add the Antress Exciter plugin to each.
As for battery life I definitely have to get some rechargeables. I was using the included batteries and the recorder died before I could finish the second band's set. Between playing with it at home and recording there I got less than 3 hours I think.
