  We analyse spectra of 26 early-type stars, with suspected binarity, using a
binary spectral model adapted for high-resolution FEROS spectra. We confirm
seven SB2 candidates (AE Pic, $\epsilon$ Vol, HD 20784, HD 208433, HD 43519, HD
56024, CD-73~375A) and derive mass ratios and spectroscopic parameters for
them. We find good agreement with theoretical models. For slightly evolved
system HD 20784 we made the first estimation of the fundamental parameters and
age $\log{t}=8.5$ yr.
