Not that it necessarily addresses the "shrill, sibilant and fatiguing" sound you reported in your original post, but any OL Silver owner using a low-medium compliance cartridge (including specifically the DL 103) owes it to him/herself to try the tweak described on the Strange Tonearm Tweak thread.
I did it back in 2003-04 and the improvement was not small. This was widely discussed for a number of years by regulars here and on Vinyl Asylum. I never heard anyone report anything but good results, typically very good.
Further if you read deep enough in that thread you'll find my post describing my partner's tweak to the tweak, which allows instant and easy fine VTF adjustment *without* moving that pesky counterweight. Very handy when fine tuning your cartridge setup.
Total cost of all the above: < $5.
