Magic returns in seldom used bookshelves?

Has anyone else pulled out a pair of less expensive ( in this case a pair of Ascend Sierra 2 non ex) speakers and really consider returning them to the "main" system.  I currently have a pair of really really nice Salk Song 3 BeAts ( mine are the ones on Jim's site in Fireburst Carpathian Elm Burl...gorgeous they are) and while I really really like them they have rarely if ever given me that "chills big huge smile" on several songs like the little Sierra's do? Everything else in system has remained consistent, but man on man, am I crazy to be considering selling my Salks and upgrading my little Sierra's to the new ex version for a nominal cost?
