        Good to see a post about dynamics ( low z mics ) Ive recently found=
 this to be a problem with the relatively new Korg MR2 vs the Sony D50. Rol=
ling dynamic mics with 280 R impedance. I see around 7 dB difference once g=
ain is applied - the actual loss figures before amplification are quite low=
 with a loss of 0.11dB (Sony) vs 0.23dB (Korg) for 280R to 10K and 280R to =
22K respectively. Lower mic input impedance would cause more loss and its n=
ot good to see this trend which seems to only consider the mic input will b=
e used for PIP powered electrets. In this regard your assumption of more no=
ise is correct.

On the other hand the D50's line is lower impedance than the Korgs which me=
ans rolling the Korg MR2 in all its DSD niceness, with an external preamp s=
uch as the RME quadmic actually results in a lower noise floor than the Son=
y D50 for equivalent gain. Swings and roundabouts... but a few dB really co=
unts with dynamics.

Kind Regards,
