The Denon 103 is AFAIK a low-output moving coil (MC) cartridge, while the Dynavector 10x5 is a high-output MC. There is a big difference in the strength (amplitude) of their signals.
The Denon's signal is very small and the phono stage you use with it must amplify a lot. If the Musical Fidelity model your husband has cannot provide this amplification, and he does not want to replace it, then you can only consider the Dynavector or Grado cartridges, which both put out a stronger signal than the Denon.
I don't know the Denon but the Dynavector 10x5 is a very musical cartridge.
Two recent audiophile-quality female vocal LPs I've enjoyed are Jennifer Warnes' The Well and Alison Krauss' Forget About It.
Happy hunting!
