Thank you. Was not aware Epson no longer sells the V750 although used ones do come up for sale on this site and others occassionally. Agree with your comments on the BSH. On my V700, noticable provements in "apparent visual sharpness" as observed on my monitor with a finely scratched negative, came about in two steps.
1. Getting a BSH (my optimum height 3.75 mm, higher than the Epson max of 3.5 mm), then later,
2. Moving to Wet Scanning. Seems to also improve micro-contrast.
I acknowledge that these conclusions have not been verified in print tests.
