I used to use the Ave Maria track from The Mission- choral, voices are added, too high and they thin out, too low and they lose their location.
I used to actively change arm height on, if not a record by record basis, then at least by rough gradients of 'thick,' 'normal' and 'thin.' (Easy enough to do on the fly with my arm). But, I've found that some cartridges seem to be far more sensitive to VTA. Right now, my cartridge is a little more agnostic (as was its predecessor) so I'm pretty much set and forget.
I still want a remote controlled arm height adjustment though. (Not laziness, it's hard to tune, run back to the sweet spot, tune, etc).
Back to our original program. :)
