I remember doing tests even with a perfectly aligned Supex SD1000 in DV505 on Linn LP12, using 3 special CBS test records they sent us.
I could even see on the oscilloscope with one of these CBS records of which one whole side is number of tracks all cut with the same amplitude 1khz sine waves, just so you could measure cartridge alignment distortion, the inner most groves had visually the worst "more" distortion than the others and the outer one was next worst, and if you can see it with your eye, believe me it's bad.
After that I was aware of it much more when playing music from then on, which really started to piss me off. Then thanks for a tangential arm Sony PSX800/XL55 Pro TT and MC I was much happier, then all changed again thanks to digital for coming along.
Cheers George
