Listening before buying is not always possible indeed.... And anyway no electronic components can be evaluated in the same manner in the different mechanical embeddings, in different acoustical fields, and in different electrical grids...And no audio system can sound the same in a showroom and in your house...If I can say that without offending him, erik_squires is right on that, but like I just said not just because our taste are different....
