Azimuth slaw. Slaw could be right as long as it is not skewed too far. But, my own inclination would be to install the Grado.
Bent Slightly Out of Shape
I scored an almost-mint Thorens TD-160 turntable last week and remembering back to the one I owned in the mid-70s, an ADC cartridge sounded very good on it. I found an ADC XLM Mk II for a reasonable price on Audio Asylum Trader and picked it up. The cartridge looks to be in good shape, other than the cantilever/stylus assembly is slightly skewed, not dead-ahead straight. My thinking is that when playing records, it will be pulled back to the correct angle by the groove-walls. Does that make sense or is it just wishful thinking? I went ahead and bought a brand-new Grado Blue also just as insurance, but I really want to install the ADC.
