I used the DL103 on my Rega Planar 3 as well. It is a great combination on the P3. The DL103R is even better than the basic version.
Other cartridges I tried are the Elys, which is not even close to the Denon. The Kontrapunkt A I have works well with my Michell Tecnodec setup, but sometimes I am in the mood for something more lively sounding and switch back to the DL103R.
Also I noticed a significant improvement for the DL103 on the P3 when I installed the Heavyweight.
Good luck,
Rene
