I am a long time Lyra Delos user (and before that Lyra Argoi). These are superb sounding cartridges if set up properly. There are a few points to consider here:
(1) the photos that you have shared are both labeled "Delos" so its not obvious what we are looking at ! .....I am surprised no-one else has noticed this.
(2) both photos show considerable cleaning needed. Lyra has a special Stylus cleaner (SPT). the easiest way to safely use is to place a drop on the red stiff stylus brush that comes with Delos and gently brush back to front. You could also use the brush that comes with SPT but be carful you don't get too much liquid on the cantilever.
(3) As you probably know all Lyra cartridges are extremely sensitive to setup. It is worthwhile to recheck all parameters (VTA,VTF in particular) once a year as these may go out by just the use of the cartridge.
(4) last but not least make sure your records are clean. Nothing damages sensitive stylus as much as dirty records.
If all fails contact Lyra (or the distributor) to evaluate the stylus. It may mean that you will be without Delos for some time but you have other excellent cartridges to keep you listening!
Good luck and let us know how you get on.
