Another option is to look at your data in their original high dimensional space, eg., with the grand tour in GGobi (, MANOVA tests the hypothesis that the means are different (assuming multivariate normality and a common variance-covariance matrix). By looking at your data you can investigate more interesting hypotheses - are the groups overlapping? is there a linear or non-linear separation between the groups? are the responses highly correlated?
