Sorry for hijacking your thread Simon!
I'm curious as well; I'll definitely try removing features (achromat, vector pulleys) this weekend and record what effect it has.
Sadly the budget won't stretch to buying a K-drive and fitting that to a mini-anni sub chassis
... and I'll have to try A/B comparing the tracks through my 96/24 DAC and hifi to hear the differences as well. Interesting also that the vinyl has its own unique fingerprint; notice at approx 13.75 seconds, on the left channel is an (inaudible to me) scratch or tick.
