Also, be aware that the effective tip mass for the SP1 is 2.6mg! Anything greater than 1mg will almost certainly damage the inner grooves, so I wouldn't use the cartridge to play your most treasured records.
decided to up the vtf by 0.25gm to 2.25gm will give that a few plays to see if there is any difference.
