Cjfrbw,
you make some very good points. why a particular product sounds the way it does is always complicated. how would one elimiate all differencs between any two designs other than a pivot and linear tracking. the answer is not likely to ever occur. so you could never get to a point where you have sufficently isolated the issues to use DBT to prove it. even then, i don't personally believe DBT proves better....at best proves differences were proved to a particular person under specific conditions at a particular moment.
so we are left to assign characterisitics based on experience.....imperfect as that might be.
my personal perceptions about linear tracking on my tt may be as much as result of the eddy current direct drive motor, and the air bearing on that motor and the 60 pound platter. it may be the vaccuum hold down, or the 250 pound plinth. it may simply be the quality of build, and not linear tracking.
my opinion is that when you do go to the trouble to do 100% of all the things that can be done to make a tt perform optimally; one of those things is linear tracking.
