Another candidate for the Audio Technica AT150MLX. It beats the pants off my DL-160 on ... well, everything, so it would be even that much better than the DL-110. You can also alter the tonal balance by playing with the VTF and VTA. I recently lowered my tonearm (SL1210 with height adjustment) a skooch and warmed up the presentation a bit. Best of all, the AT150MLX has a
replaceable stylus for $180.
You also might be a candidate for the Zu103. It's a low-compliance cartridge which should have a more rugged cantilever. Although your tonearm is probably optimized for a medium-to-high compliance cartridge, the Zu version of the DL-103 weighs a lot more than the stock DL-103, thus raising the tonearm's overall effective mass into the 103's comfort zone.
Those wood-bodied Grados are also probably a good suggestion as a lower cost replacement for the original wood-bodied Clearaudio cartridge.
Still, the AT150MLX has the sound of a high resolution cartridge. The cantilever is pretty fine but has held up well for me. I've owned mine for 8 years and clean the stylus regularly with a piece of Magic Eraser. No bends, crimps, or breaks.
