If the detail is there in the scan, then the enlarger will also be able to produce it on paper. You may need to print on higher contrast, and your exposure times will be shorter. I have printed fairly thin negs with surprisingly good results using a diffuser light source (M605 with a colour head). A condenser source should, in theory, produce slightly more contrast, but I think a better approach is just to pick an enlarger based on your overall needs. Colour heads are very convenient for variable contrast printing. The lens can also reduce contrast due to flare, so using a late generation multi-coated lens will definitely help to keep the contrast up. All in all you should be quite fine with a diffuser head and good lens.
