that arm isn't the best match-up for the oracle, due to its spring arrangement, & the way the et will cause weight-shift to the oracle as the arm moves. i assume ewe have an older oracle - i can't imagine this arm wood get mounted today on a gnu oracle mkv. the arm wood perform much better w/the awailable upgrades to the oracle, specifically the counterweight upgrade, but i'd also recommend the bearing & spring upgrades as well.
re: bdifferent tonearms, i'm *wery* pleased w/the origin-live modded rega rb250. a great arm at any price, but a *steal* cuz it's so relatively cheap. origin-live sez it's even better than their modded rb900...
i'd also check out o-l's motor/power-supply mod. a worthwhile upgrade to my oracle, again a steal at the price...
