Denon DL-103/103R or DL-301II

I'd really like to hear some opinions on these carts, especially comparisions from folks who have used both. I listen to mostly classic pop/rock with some classical thrown in. I considered starting out with the DL-160 but I suspect the voltage might be too high for the MC stage and too low for the MM.

I will be using a Denon DP-500M tt - PRA-S10 preamp - POA-S10 monos. I'm absolutely new to vinyl and don't really understand the "impedence" aspect (nor the "abnormally low" signal to noise ratio for the MC stage) but I'll list the specs for my preamp:

Input sensitvity Impedence -
PHONO MC: 0.2 mV/100ohms
PHONO MM: 2.5 mV/47K kohms

Max input level-
PHONO MC: 13mv/1kHz
PHONO MM: 160mv/1kHz

Max output- 10V/150mV

Signal to noise ratio:
PHONO MC: 79db (at 0.5mV input)
PHONO MM: 96db (at 5 mv input)

I'm looking at the Denon carts because all my equipment is made by them but if there are better choices ( including MM cartridges) out there I would love to hear those opinions as well.

Thanks
