Mine's mostly from enlargers, many years ago:) All I can say is that I bought a condenser head for a Durst which already had a diffuser head, because I wanted sharper, contrastier, as alleged. And I was miffed to find that, apart from being almost exactly one paper grade contrastier I could see no difference. If I used a harder grade with the diffuser head, I could see no benefit at all from the condenser head even using a magnifier. All I could see was marginally more blown extreme highlights, already a problem with the (then new) straightline films like TMax, more scratches and marks. The condenser head went back in its box and stayed there.
