I purchased a "very low hour" used Art 9 from an individual, it showed the same symptoms as the OP cartridge, only it was heavy on the right channel.
I quadruple checked Azimuth and all settings, still the same results. It was a defect or misaligned stylus.
I contacted the seller immediately and retuned it that day.
