the denon step ups are mostly deisgned around the classic 103 and not the lower impedance 103 R but some, like B50 above, find them to be a good match for the R version too.
I'm using a Denon AU300-LC SUT with my DL-103R cartridge with great results, and before that I was using the same SUT with a DL-103 with equal results. The AU300LC is a fine match for either of these cartridges.
According to Denon's specs -
DL-103 output impedance = 40 ohms
DL-103R output impedance = 14 ohms
AU300-LC recommended cartridge impedance = 3 ohms through 40 ohms
I see no conflicts or mismatches there, and that's backed up by my real world experience.
