Dear Almandog: I own that cartridge an works beautiful at 100 ohms. Btw,, according with the phono stage ( you own ) manufacturer specs that phono stage works well with LOMC cartridges with an output level as low 0.2mv, the DL-S1 has a lower output than that figure so chances are that you can't achieve the best performance for that cartridge.
Regards and enjoy the music,
