Thank you very much for interesting observation. First of all, I used ONE Nbot Platinum connected with M10 and D100 by split cables…So the same preamp with different recorders.. Later I will post the picture of the gears.
It was very hard for me to put it but it might be correct to say D100 has more “in your face” or more upfront sound signature. One thing I noticed is that D100 sounds really smooth. IMHO, M10 sometimes sounds hash or wavering on either top-end or the bottom. But as far as tight bass goes, I think Nbox Platinum is the major factor to that differences.
After everything I said on thread linked below, http://taperssection.com/index.php?topic=170199.msg2208469#msg2208469
I am inclined to believe that D100 has tight bass not because of recorders choice but because of Nbox versions’ differences. Since regular Nbox or Nbox+ used “old school” preamps which consumes more battery power but gives them a “warmer” sound, you might have had that impression but take a listen to the Bob Dylan samples linked above. I taped the two nights in a row at the same venue using the same mics with the same recorder from the almost same location (only a few seats away). Once you listen to the samples, I am sure that you will get an idea.
To record a loud rock show, M10’s recording level was set at “4” and D100’s at “5 or even 6”. D100 has more gain available, which gives us more chance to remaster it in the post.
If you have M10 already, maybe you do not have to get D100 but if you have a chance to use both of them, it would be cool to use DTS(32 bit) on D100 and 24bit on M10 as a back-up… The size could not be the issue once you get used to it. But if you try to use Preamps with M10 and D100, you would be ridiculed for your gigantic alien ass.
I will tape some other shows with Nbox+ very soon and will definitely share some samples here.
As for GNR’s recording, I will probable upload the whole recordings not very soon though.
